Screw-in Test Probes

Many press-in test probes offered by INGUN are also available as a screw-in version.
They remain securely positioned in the receptacle even under challenging test conditions with vibrations or axial force (probes will not move out of the receptacle).
Screw-in test probes with thread have the designation ‘M’ at the end of the part number.

Cable harness and connector testing
Screw-in test probes are often used to contact cable harnesses and plug connectors.

Cable harnesses are the central connection elements between various components in the automobile industry and mechanical engineering and supply these with either power or signals.
To guarantee uninterrupted operation, high demands are placed on the cable harness as well as the plug connector used.
The cable harness has to pass various tests before it is fitted, these include: connection test, position test, push-back test, and function test.

A further area of application for screw-in probes is the contacting of plug connectors on various electronic devices, such car radios, control units, PCs, smart devices, and many more.

Step probes
Are inserted in the plug housings to test the correct position of the contact terminal (contact sheets). A contact will only be produced by the pin of the step probe when it is correctly positioned.
INGUN offers a wide variety of step probes with tip dimensions, stop collar (disk) dimensions, and pin length.

Push-back probes
When finally plugging the plug connectors together, it is important that the contact terminals (contact sheets) remain in the correct position, and cannot be pushed back.
For this test, push-back probes with a spring force of up to 34 N are used.

Non-rotating probes
For testing flat connector blades or jacks which can only be contacted in one position, non-rotating probes are used. These probes are already aligned in the correct position during assembly.
