Slkor Launches Revolutionary Low-Power Hall Switch SL1603SL, Redefining Sensing Performance for Portable Devices

Slkor's SL1603 Hall switch sensor redefines ultra-low-power sensing with industry-record 1.6A@1.8V (5Hz) consumption in a SOT-23 package. Featuring omnipolar magnetic response, dual-selectable thresholds (33G/46G), and 8KV ESD robustness, it enables 40% longer battery life in TWS earbuds, smart locks, and industrial IoT devices. Standard tape-and-reel packaging ensures rapid deployment.
Ultra-Compact SOT-23 Package Achieves 1.6A Power Consumption, Enabling Battery Life Breakthroughs in TWS Earbuds and IoT Devices

Advanced sensor technology leader Sikor today announced the SL1603 [https://www.slkoric.com/hall-effect-sensor/sl1603sl.html]Series, a new ultra-low-power Hall switch sensor. Featuring an industry-leading 1.6A@1.8V standby current (5Hz version), omnipolar magnetic response, and dual-selectable thresholds (33G/46G), this solution delivers precision non-contact detection for space-constrained battery-powered devices. It boosts energy efficiency by 40% in TWS earbuds, smart locks, and other compact applications.
