Secure Connection - Spring-Loaded Connectors

Spring-Loaded Connectors create an electrical contact between two components. As Pogo Pins, they are used, for example, wherever it is necessary to charge the rechargeable batteries in mobile devices such as scanners, card readers, communication devices, etc.

The special design of the test probes which are used here adapts perfectly to an extremely wide range of contact situations. The spring-loaded connectors guarantee a clean connection on almost all surfaces, including with ambient conditions in which oscillations and vibrations could affect the contacting. Irrespective of the specified installation height of the pogo pins, the spring-loaded connectors compensate for unevenness and differing heights on the contact surfaces. These features ensure a perfect and safe electrical contact.

When positioned in the right place and used correctly, the pogo pins can achieve up to 1 million contact cycles. One typical application for pogo pins is their use in spring-loaded connectors. They can be used for the secure connection of two PCBs which, by means of flexible contacting technology, can be connected and disconnected as often as required. This especially flexible connection of the spring-loaded connectors requires only a contact surface which is larger than the diameter of the probe head, so it offers considerable advantages when compared with connectors, which always require a precise connection. Additional arguments in favour of the use of spring-loaded connectors include the absence of insertion and withdrawal forces, and minimal wear and tear.
