Presence detection using an insulating shroud

Insulated head probes are used for circuit board component lead detection and testing. The insulating shroud is raised slightly higher than the metal serrated tip. During test, if the component lead or connector pin is set correctly, the electrical contact will be made. Pins absent or misaligned will cause the shroud to make contact first and fail the test.
