100-Pack P75-E2 / P75-E3 Gold Plated Spring Test Probe Pogo Pins
Upgrade your electronics testing and DIY projects with this professional-grade set of 100 gold plated spring-loaded pogo pin test probes. Designed for reliable, repeatable electrical contact in PCB testing, fixture building, and prototype development, these P75-series pogo pins deliver consistent performance in a compact, precision-engineered form factor. Made in Mainland China.
Why Choose These Pogo Pin Test Probes?
- Gold Plated Finish: Beryllium copper plunger and music wire spring with gold plating ensure low contact resistance and long-lasting corrosion resistance.
- Dual Model Options: Includes both P75-E2 (1.3mm conical needle tip) and P75-E3 (1.5mm needle tip) variants for versatile application coverage.
- Low Contact Resistance: Only 50mΩ current resistance ensures accurate signal and power transfer in test fixtures and bed-of-nails jigs.
- 3A Current Rating: Suitable for a wide range of low-to-mid current electrical test applications.
- Compact & Precise: At just ~16.5mm total length with a full stroke of 2.50mm, these pins are ideal for tight PCB layouts and miniaturized test setups.
- Value Pack: 100 pieces per package — perfect for stocking your workbench or outfitting a full test fixture.

Frequently Asked Questions
Q: What is the difference between the P75-E2 and P75-E3 pogo pin test probes?
A: The P75-E2 has a conical needle tip diameter of 1.3mm, while the P75-E3 has a slightly wider 1.5mm needle tip. Both share the same 1.0mm needle tube diameter, 16.5mm total length, 2.50mm full stroke, and 3A current rating. Choose E2 for finer contact points or E3 for slightly broader tip coverage.
Q: Are the pin sheaths/sockets included in this 100-piece pack?
A: No — only the pogo pins (probes) are included in this 100-piece set. Compatible pin sheaths (needle sheath diameter 1.32mm) are sold separately. A drill size of approximately 1.4mm is recommended for mounting.
Q: What materials are used in these pogo pin probes?
A: The plunger is made from heat-treated beryllium copper for durability and conductivity, while the internal spring uses music wire. Both are gold plated to minimize contact resistance (50mΩ) and resist oxidation over time.
Q: What is the maximum current these test probes can handle?
A: These P75-series spring test probes are rated for up to 3A of current, making them suitable for a wide range of low-to-mid power PCB testing, programming fixtures, and prototype validation setups.
