Your Reliable Pogo Pin Manufacturer

Spring loaded pin is an electrical connector structure used in modern electronics applications. They are more durable than other electrical connectors. The name spring loaded pogo pin comes from the pin’s resemblance to a pogo stick – the integrated helical spring in the pin applies a constant normal force against the back of the mating receptacle or contact plate, counteracting any unwanted movement which might otherwise cause an intermittent connection.

A basic spring loaded pin consists of 3 main parts: a spring loaded plunger pin, spring loaded locking pin, and a spring. Because of customers’ different applications, different design concepts are required, including Bias Tail, Back Drilling, Ball, T-pin type, or Coaxial. Of 4 designs, designs of T-pin/Ball/Coaxial can meet the requirement of high current, up to 15A or upper, its resistance is ＜30mΩ. Bias Tail can greatly improve the stability of Spring Loaded Pin, the current is ＜3A, and resistance is ＜30mΩ.  Back Drilling can greatly save design space, suitable for minimal space design, the current is ＜1A,  resistance is ＜200mΩ.

• Free Height:   is no load height, full extension height of spring
• Working Height:  is the ideal load height for spring
• Maximum Load Height: is the maximum load height of the spring, usually, contacting the end of the barrel

• Spring loaded pin, because barb on the barrel, very stable after mounting onto the housing
• Stopper on the bottom of Spring Loaded Pin, very strong fix into housing too
• IIn the range of ±10°, no dropping for the Spring Loaded Pin life cycle, but, when the angle is 15°, the life cycle will drop accordingly

• At Dongguan Proma, the Spring loaded pin life cycle is in the range of 10,000 to 100,000 times
• Mechanical life cycle:  maximum working times to ensure spring force in spec
• Electrical life cycle: maximum working times to ensure contact resistance in spec
