What are the key features of Spring Contact Test Probes?

Spring contact test probe are also referred to as Pogo Pins, Contact Pins, Bed of nails, Fixture pins, Spring Pins and Test Pins. These are made up of a tubular barrel, a spring and a plunger with gold plated as gold is an excellent electrical conductor and is resistant to corrosion. Contact is making through various test points on printed circuit boards (PCB’s), components and wiring fields through this spring contact test probe. The probes can be used to test connector-cable systems, when it employed in special test modules. Variety of tip style and different spring pressure are provided in the plunger tip style. Probes can be mounted into housing unit when an electric connection is made.

The spring loaded tip of the test probe will provide a reliable electrical contact to the target whose distance away may well be indeterminate. The main uses of these test probe are in vacuum test fixtures associated with automatic test equipment (ATE).They are also used inside a functional test station as part of a larger production line. The design of spring test probes is done in such a way that the use of the use of a receptacle allows the test probe to be removed for cleaning or replacement without having to disconnect the electrical cable. The electrical cable is connected to a receptacle which is the frame through this the test probe is inserted into.
