Production testing of passive entry sensors now available
Published on 15th December 2017
Latest developments to the Genix Test Unit allow for presence and correct engineering revision testing of passive entry sensors.
Automotive sub-assemblies such as bumpers and spoilers typically contain an array of electronic components, such as parking assist sensors, pedestrian sensors, gesture equipment, fog lamps, telecommunications amplifiers and receivers.
As technology advances, each of these components will evolve, such that sometimes separate engineering revisions come to exist that are incompatible with each other.
In line with these technological advances comes new and innovative functionality – for example, passive (or keyless) entry systems.
Given that components of the same generic type often share a form factor, in-line electrical testing may be required to distinguish components that are identical to the naked eye. Furthermore, just-in-time manufacturing requires that sub-assemblies arrive in a guaranteed functional state.
The Genix Test Unit provides a means of performing a number of electrical and communications tests on products at assembly stations during manufacture. The system has been designed for testing a range of electronic components within sub-assemblies, such as bumpers and spoilers, at the end of the production line.

As well as substantially decreasing the risk of commercial recalls, the GTU performs its tests in a matter of seconds, decreasing takt time on the production line, resulting in much quicker and efficient testing cycles.
The test unit has a high I/O count supporting a wide range of simultaneous tests and includes PLC interfaces for test control, result capture and handshaking. It’s capable of providing both advanced continuity and functionality testing via LIN, CAN and PSI5 and optional other protocols, such as SENT.
Typically, test results are fed back to the PLC. Custom handheld devices can be provided for monitoring of test results or alternatively, these test results can be monitored via our real-time systems interface creation software, VISUALCONNX, with a custom GUI. The unit can be mounted in a wide variety of locations within the manufacturing environment. Plugable screw terminal blocks for I/O and power are provided with each test unit.
