Capacitive encoders, as a new feedback technology that has emerged in motion control, robotics, semiconductor equipment, and high-end industrial automation in recent years, offer core value by addressing the limitations of traditional optical encoders in dusty/oily/condensate environments (poor reliability, stringent installation tolerances, limited shock and vibration resistance), and magnetic encoders in terms of high precision, high resolution, and long-term stability. In various applications such as machine tool linear axes, collaborative robot joints, semiconductor handling platforms, AGV/AMR wheels, and medical imaging equipment rotating platforms, optical encoders are easily contaminated by dust or oil mist, leading to signal loss or frequent maintenance. While magnetic encoders are resistant to contamination and vibration, they suffer from significant disadvantages in high resolution (>20 bits), extremely low nonlinear error, and temperature drift control. Capacitive encoders calculate angles or displacements by arranging periodic electrode patterns on the rotor/belt and stator, utilizing the amplitude/phase information generated by the change in capacitance matrix with position. They do not rely on transparent optical paths or require permanent magnets. They maintain a high signal-to-noise ratio even in environments surrounded by metal shavings, oil mist, moderate condensation, and moderate electromagnetic interference. They also offer wider installation tolerances and a thinner, lighter design, making them particularly suitable for space-constrained applications requiring low inertia, long lifespan, and maintenance-free operation. In 2025, global sales of capacitive encoders across various applications reached approximately 23 million units. Based on system design and purchase orders, the unit price was approximately USD 52, with a gross profit margin of approximately 28%-38%. Typical product structures include: a rotor disk or linear scale with periodic electrode patterns (multilayer PCB, glass, or metal substrate), stator-side excitation and receiving electrode arrays, a dedicated capacitance measurement ASIC, signal conditioning and interpolation circuits, interface conversion modules (ABZ, SSI, BiSS-C, SPI, RS-485, TTL/RS-422 differential output), housing, and bearings/mounting flanges. General parameters typically include: resolution 12-22 bit (up to 23-24 bit absolute value for high-end models), system accuracy ±10-±60 arcseconds (up to several arcseconds for high-end aerospace/robotics models), operating speed 3,000-10,000 rpm (up to several m/s for linear models), supply voltage 4.5-5.5 V or 9-30 V, operating temperature -40 to +105 °C, and vibration resistance meeting industrial or military standards. Typical usage: A six-axis industrial robot typically uses 6-7 capacitive encoders (including joints and additional axes); a semiconductor conveyor/exposure platform uses 3-6 linear/rotary capacitive encoders; a mid-to-high-end servo motor test bench or turntable uses 1-2; and a medical imaging device (such as a CT/Gantry) uses 1-3. Upstream in the industry chain, capacitive encoders mainly rely on high-stability PCBs/glass substrates, copper/aluminum electrode materials, high-stability dielectric materials, dedicated capacitance measurement ASICs and mixed-signal chips, connectors, and cable assemblies. Downstream, they are concentrated in robot and collaborative robot manufacturers, machine tool and motion control system manufacturers, semiconductor and electronic manufacturing equipment manufacturers, AGV/AMR manufacturers, and medical imaging and aerospace equipment companies.
Supply Situation
Upstream raw materials and key components mainly include multilayer high-stability PCBs/glass or ceramic substrates, high-purity copper/aluminum electrode materials, high-resolution photoresists and developing chemicals for capacitor structure patterning, dedicated capacitance measurement and interpolation ASICs, industrial-grade connectors and cables, and aluminum alloy/stainless steel materials for housings and mounting components. The combined cost of raw materials and semiconductor devices accounts for approximately 50%-62% of the total cost. Key suppliers include Rogers Corporation, Schott/Corning, JX Nippon Mining & Metals, TSMC/GlobalFoundries, and TE Connectivity, etc.
Manufacturer Features
Kappasense focuses on absolute linear capacitive encoders, specializing in linear platforms and high-precision motion control applications; Same Sky has achieved large-scale installations of its AMT series capacitive rotary encoders in servo motors, stepper motors, and robot joints, possessing strong standardization and cost advantages; Netzer, in the aerospace, defense, and high-end robotics fields, leverages its ultra-thin, large-aperture capacitive absolute encoder technology to maintain a significant technological advantage in high-end application scenarios.
Example
In 2024, Kappasense participated in a project for a high-end collaborative robot and direct-drive rotary table production line in Europe: the project planned to uniformly adopt capacitive position feedback on 22 newly built collaborative robot and linear transport platform production lines to replace the original optical and some magnetic encoder solutions. In the final solution, Kappasense provided approximately 2,800 linear capacitive encoder modules for 14 high-precision linear transport platforms. This project, in its technical bid, outperformed some optical and magnetic encoder solutions with its comprehensive advantages of "wide installation tolerances + contamination resistance + high resolution + maintenance-free operation," and reduced overall line integration and spare parts management costs through a unified interface and software tools.
Applications
Capacitive encoders are widely used in various application scenarios, including joint feedback in industrial and collaborative robots, linear/rotary axis measurement in CNC machine tools and machining centers, semiconductor and panel equipment (exposure stages, alignment platforms, handling modules), AGV/AMR and motor drive systems, elevators and automated warehousing systems, medical imaging equipment (CT/rotary gantry), aerospace attitude/control surface control, military and high-end testing platforms, etc. They are an important supplement and replacement for optical and magnetic encoders in scenarios requiring "high precision + high reliability + complex environments + installation constraints." Typical downstream customers include high-end equipment manufacturers such as FANUC, KUKA, ABB Robotics, and ASML/Canon, as well as motion control platform manufacturers such as Siemens Motion Control.
Product Advantages
Compared to optical encoders, capacitive solutions do not rely on transparent optical paths, making them significantly less sensitive to dust, oil mist, and condensation. They also offer wider installation tolerances and allow for thinner, lighter disks. In space-constrained and high-vibration environments such as robot joints, direct-drive turntables, and semiconductor handling modules, this significantly reduces assembly difficulty and after-sales calibration costs, minimizing downtime caused by optical path contamination. From an operational perspective, reduced equipment failure rates and maintenance frequency, fewer spare parts SKUs, and improved overall MTBF and availability allow OEMs to highlight "high reliability + low total lifecycle cost" in bidding processes, while also creating a differentiated selling point and bargaining power against competitors still dominated by optical/magnetic encoders.
Technology Trends
Technological upgrades are concentrated in four directions: First, improved resolution and accuracy. Through more refined electrode pattern design, lower-noise capacitance measurement ASICs, and high-order interpolation algorithms, capacitive encoders can maintain wide installation tolerances and high contamination resistance while pushing absolute resolution to 23-24 bits, and system accuracy further approaching or even surpassing high-end optical encoders in some scenarios. Second, lightweight structure and large aperture. Ultra-thin, large-aperture capacitive encoders, represented by manufacturers such as Netzer, are gradually replacing some optical/magnetic solutions in robot joints, aerospace turntables, and large motors, reducing rotational inertia and freeing up space in the central aperture. Third, integration and modularization. The Same Sky AMT series and others are directly compatible with NEMA motor frames through modular kits, providing the encoder, installation adapters, and software tools all at once, reducing the development and assembly complexity for OEMs. Fourth, environmental adaptability and functional safety. Capacitive encoders are incorporating redundant channels, self-diagnostic, and fault detection functions to address scenarios with higher safety requirements, such as robots, human-robot collaboration, and autonomous driving chassis. Compared to optical and magnetic encoders, capacitive encoders are establishing a clear and independent technological position due to their comprehensive characteristics: resolution approaching that of high-end optical encoders, anti-fouling/wide tolerances approaching or exceeding those of magnetic encoders, and cost and power consumption falling between the two.
Market Influencing Factors
The growth of the capacitive encoder market stems from two main factors. Firstly, the expansion of new application scenarios: the increasing demand for high-end motion control in fields such as robotics, collaborative robots, AGVs/AMRs, battery and semiconductor production lines, medical equipment, and aerospace is amplifying the need for feedback devices with high precision, high reliability, and wide installation tolerances. Secondly, the technology substitution effect: In dusty, condensation-laden, oil-mist-vibration environments, optical encoders face high maintenance costs and downtime risks, while magnetic encoders have shortcomings in high precision and temperature drift. This is prompting OEMs to experiment with or mass-produce capacitive encoders in their next-generation equipment, leading to a re-division of labor among the three technological routes: high-end optical, capacitive, and magnetic. The growth rate of the capacitive encoder market is significantly higher than the overall encoder market growth rate and the magnetic linear/partial rotary encoder market growth rate, while its growth rate is comparable to or even slightly higher than that of high-end optical encoders in certain market segments. Optical encoders still hold the largest share of the overall encoder market, while capacitive encoders currently account for only 5-10%. However, the latter's penetration rate is rapidly increasing in new applications such as robotics, semiconductor equipment, ultra-thin turntables, and collaborative robots, making it a "smaller but fastest-growing" segment. With the increasing trends of machine replacement, flexible manufacturing, smart factories, and high integration of motors/robots, capacitive encoders, relying on their higher environmental adaptability, wider installation tolerances, thinner and lighter structure, and continuously improving resolution/accuracy, will continue to replace optical and magnetic encoders in certain scenarios, both in specific areas and in incremental expansion. In high-precision and clean environments, high-end optical encoders still have an advantage; in extremely rough environments and cost-sensitive scenarios, magnetic encoders remain the mainstay; and applications that require both high precision and strong adaptability are becoming the core battleground for capacitive encoders. The overall market structure presents a trend of "optical dominance, magnetic stability, and high-growth capacitive encoders catching up," and the market share of capacitive encoders in the overall encoder market is expected to continue to increase in the coming years.
