What Are Pogo Pins Used For?
Pogo pins (spring-loaded contact probes) are the go-to solution for electronics engineers and hobbyists who need temporary, reliable electrical connections without soldering. Common uses include:
- PCB functional testing and in-circuit testing (ICT)
- Firmware flashing and programming jigs
- Battery and charging connector assemblies
- Robotics and automation contact points
- DIY electronics and maker projects
Why Choose Qme P50-B1 Pogo Pins?
Qme manufactures these probes to tight tolerances, ensuring each pin delivers consistent spring pressure and low contact resistance over thousands of cycles. The gold-plated tip resists oxidation, keeping your connections clean and stable even after extended use in test fixtures.

Frequently Asked Questions
Q: What is a P50-B1 pogo pin and what are its dimensions?
A: The P50-B1 is a standard spring-loaded test probe pin with a diameter of 0.68 mm and a total length of 16 mm. The "B1" designation refers to the pointed tip style, which is ideal for making precise contact on small PCB test pads and solder points. This pack includes 100 individual pogo pins, each rated at 75g spring pressure.
Q: What applications are these pogo pins suitable for?
A: These P50-B1 pogo pins are widely used in PCB functional testing, in-circuit testing (ICT) fixtures, firmware programming jigs, battery connector assemblies, Arduino and Raspberry Pi projects, and any application requiring a reliable temporary electrical connection without soldering. Their 0.68 mm diameter makes them suitable for tight-pitch layouts.
Q: How do I install pogo pins in a test fixture?
A: Pogo pins are typically press-fitted or soldered into holes drilled in a PCB or custom fixture plate. The P50-B1 pin's 0.68 mm diameter requires a corresponding hole size in your fixture. Once installed, the spring mechanism provides automatic compensation for slight height variations, ensuring consistent contact across all test points.
Q: Are these pogo pins compatible with standard test jigs?
A: Yes. The P50-B1 is one of the most widely used standard pogo pin formats and is compatible with the majority of commercially available bed-of-nails test fixtures and DIY jig setups designed for this pin series.
