Testing of RJ connections – Testplugs for RJ45, RJ11, RJ12
End-of-line testing of electronic equipment is becoming increasingly significant as an important component of modern testing strategies, both in the telecommunications industry as well as in the automotive and industrial electronics. Today's standardization of plug connections is essential for an economically meaningful development of efficient and highly wear resistant test plugs.
RJ connections are modular plugs and sockets, which are used for telephone and network wiring worldwide. As early as the 1980s these interfaces were introduced to the American market and standardized a few years later. The plugs and sockets are available in different designs and pin assignments, which are described in international standards. The terms applied comprise the letters RJ (Registered Jack) and two digits, which define the concrete type of connection.
The most common RJ plug connections used in the PC and telephony segment are 6pin and 4pin modular plugs (for phone, fax, and modems) and 8pin “RJ-45”-plugs (for ISDN- and Ethernet-interfaces).
Industrial-strength test plugs for testing these interfaces are provided by ENGMATEC GmbH in Germany. The plugs have been designed specially for application with incircuit and function tests.
As test systems often run in 3-shift operation, plug contacting units have to resist an amount of several thousand connecting cycles per day. This requires testplugs specially developed for this application.
ENGMATEC plugs are manufactured from high performance plastics, which guarantees an optimal abrasion resistance. Contact wires made of copper beryllium (CuBe), particularly suitable for a high number of connecting cycles, are bonded into the plug base.
A specially developed plug enables a wear resistant contacting of the sockets and prevents a damage of the contact springs.
The following accessories are additionally available:
- Floating mounting shoes, self-centring devices
- Cable and plug assembly to customers' requirements
- Complete connecting unit with pneumatic actuation and sensors for position monitoring
ENGMATEC’s delivery program for connectors covers all usual sockets such as Western mini, USB and TAE. Special forms, special lengths and coded plug forms are realizable on customer's request.
ENGMATEC’s central business area is the development and production of systems in the field of assembly automation and testing technology. We solve specific customer requirements for the electronic and electrical engineering branch.
The automation division comprises completely and partially automated production lines, rotary index tables, robotics, stand-alone stations and handheld devices.In addition to the assembly mounting the systems are often equipped with integrated measurement and test systems.
In addition, an extensive board handling program for printed circuit boards, soldering frames and workpiece carriers complements the product range:
- Loader / Unloader
- Handling systems
- Marking- and Recognizing-Units
The field of measuring and test equipment includes standard modules for in-circuit testing and functional testing (desk adapters, drawer adapters, in-line test systems), temperature testing systems and connections for electronic plugs.
Focal points are the areas of telecommunications, automotive industry, computer engineering, household appliances and equipment, activities in RF and RV engineering and entertainment electronics.
ENGMATEC GmbH covers the full spectrum of services from design to service and maintenance.
