High precision pin inspection of connector assemblies

Application and SolutionConnector Inspection

Connectors must be manufactured precisely so that the pins fit onto the circuit board during assembly. Until now, mechanical test gauges have been used to check the position of the individual pins. However, these are inflexible and the inspection is very time-consuming. If a pin is missing or broken off, this cannot be detected with the mechanical plug-in gauge. In addition, the part may be abraded or bent.

With senswork's virtual connector gauge, the smallest deviations in connectors can be detected before damage occurs. With the help of a high-resolution camera system, a precise, virtual image of the PCB or socket is created. The system then checks whether all pins fit on the PCB or socket.


  • Pin position verification
  • Detection of shape defects


  • Extremely short evaluation time: 20 ms
  • Flexible process: Suitable for all connector types
  • Contact-free and wear-free
