Test plugs are assemblies made from different high-performance materials. They are used as standard for reliable 100% testing of vehicle electronics by leading manufacturers in the automotive industry. They are supplied directly ex works as a plug-and-play module. Also ideal for combined function/swash circumference tests thanks to the optional infeed ramp.

The material combination of high-performance ceramics, engineering plastics and metal provide a perfect balance of all required properties:

Our ceramic test plugs perform multiple tasks simultaneously. First of all, of course, they perform functional tests and the programming if necessary. The swash circumference test then checks the pluggability of the assembly. The swash circumference describes how far the contact pins are permitted to deviate from the target position in the X and Y direction. Its size is specified as a diameter. If the pins deviate from it, they are pressed against the very hard but fracture-resistant ceramic test plug during the test process and the drive system stops. This approach ensures that rejects are easily detected.

Beneficial characteristics of the ceramic test plugs:

  • Extremely wear-resistant ceramic for substantially longer service lives
  • Non-magnetic
  • Can also be used to realise the smallest geometries: 0.3 mm wall thickness
  • High technical purity: no abrasion in the component, no incorrect measurements, no premature failure of the pogo pins
