Spring Contact Test Probes are also referred to as:
Spring Contact Test Probe
- Pogo Pins
- Contact Pins
- Bed of nails
- Fixture pins
- Spring Pins
- Test Pins
Spring Contact Test Probes are used to make contact to various test points on printed circuit boards (PCB’s), components and wiring fields. When employed in special test modules, the probes can be used to test connector-cable systems. The test probes can also be used in control engineering units or as a charging contact.
Spring Contact Test Probes are made up of a tubular barrel, a spring and a plunger. Plunger tip styles can be provided in a variety of tip styles and different spring pressures. This ensures the best contact with the test surface.
Probes can also be mounted into receptacles (housing units) where an electrical connection is made. This also allows the test probes to be easily removed for repair or replacement.
Contact Probes are available for various applications. Below is a brief overview.
-
ICT/FCT series - Probes for fixtures. Standard ATE probes for centers 50mil, 75mil and 100mil
-
Short Travel Probes/Battery contact series - Compact probes with limited travel. Frequently used as a battery contact
-
Interface Probes - Interface between fixture and test system are usually realized by this option
-
Pneumatic Probes - For selective contacting of single test points with limited access
-
Threaded Probes (screw in) - Threaded for a secure fit. Used in modules for the test of wire harnessing
-
High Current Probes - Used for high current applications
-
Switch Probes - Special probes with integrated switch element mainly used for presence tests
-
Push Back Probes - During the push back of connectors, the tight seat of the connector elements is verified
