High Current Pogo Pin Connector

Dongguan Xinteng Electronics Co., Ltd. is one of the most reliable manufacturers and suppliers of high current pogo pin connector in China, featured by quality products and good service. Welcome to wholesale bulk durable high current pogo pin connector in stock here from our factory. Also, customized service and OEM&ODM service are available.

This Pogo Pin connector features a circular structure and a 7.0mm pitch. The relatively wide pitch is designed to meet the insulation safety distance requirements for high-current transmission. It can carry a maximum current of 10A and has a service life of 50,000 cycles. The contact force is 300g ± 20% at a working pressure of 2.1mm.

The Pogo Pin is made of highly conductive brass with a thick gold plated surface to reduce contact resistance and prevent oxidation. Due to the high current transmission requirements, the pin diameter is designed to be 3.0mm. A smaller pin diameter can easily overheat and even affect spring performance. A proper design ensures stable contact under high loads.

1. First, Pogo Pin connectors rely on a spring mechanism to achieve contact. They consist of a male end (a spring-loaded Pogo pin) and a female end (a flat or recessed contact). During use, the male and female ends must maintain precise alignment, with a generally recommended tolerance of ±0.1mm. Excessive misalignment can lead to "pin jamming" or "pin misalignment" during mating, deforming or even damaging the pin tip.
2. Pogo Pin connectors can be mounted using various methods, including DIP soldering, SMT mounting, or screws. Both DIP and SMT Pogo Pin connectors are suitable for applications in small devices, such as handheld testers and wearables. The DIP method is more stable and ensures pin verticality, while the SMT method saves space and is therefore suitable for wearable devices. For test fixtures or tooling, a press-in design can facilitate replacement, allowing for quick replacement and maintenance of pin modules.
3. The compression stroke must be controlled in the docking design. Engineers will mark the compression stroke of each Pogo Pin on the drawing. It's crucial to use it within the indicated compression range. Overcompression can damage the spring, while shallow compression can cause poor contact. The best practice is to compress the pin to the middle of its stroke after assembly. This ensures stable contact and prolongs life.
4. In terms of electrical performance, high-current Pogo Pin connectors require attention to contact resistance and heat generation. This can be achieved by increasing the copper foil width on the PCB or implementing heat dissipation. It's recommended that Pogo Pins be plated with thicker gold to reduce contact resistance and resist oxidation.
5. When plugging and unplugging, try to maintain a vertical insertion direction and avoid angled insertion. Pogo Pins have a guide taper, but inserting at a steep angle can easily damage the plating. Over time, the gold plating wears away, the tip oxidizes, and the contact resistance increases.
