Through Hole Pogo Pin Connector

How to Choose the Right Through Hole Pogo Pin Connector

A through-hole pogo pin connector solders into plated holes for a strong mechanical anchor. The right connector depends on your pin count, board thickness, current, and plating. Use the steps below to spec it before requesting samples.

1. Set the pin count for your interface. Our through-hole connectors run from 2 to 8 pins. Pick the count that covers your signal and power lines. Send your pinout and we’ll match the layout.
2. Match the connector length to your board. These connectors run 4.7 mm to 47.55 mm long and 2.5 mm to 14.76 mm wide. Pick a body that seats in the holes and reaches the mating surface. Share your board detail for a fit check.
3. Set the working height for firm compression. Working height ranges from 3.9 mm to 13 mm. Spec the height where the pins hold firm contact without bottoming out. We’ll model the travel against your mating gap.
4. Choose the current rating for your load. Through-hole connectors carry 1A to 3.5A per pin. Match the rating to your peak load with headroom. We widen the barrel and plating when your design needs more.
5. Pick the spring force against vibration. Spring force runs 30 gf to 120 gf across the range. Higher force holds contact under shock and vibration. Lighter force suits low-insertion-force docks.
6. Choose the plating for your signal path. Plating spans Au 1u to Au 50u, plus an AP2 composite option. Thicker Gold or AP2 holds low resistance on demanding signal paths. Tell us your cycle count and environment for the right finish.
7. Not sure which connector fits? Talk to our engineers. Send us your pinout, board thickness, and mating gap. We’ll match a catalog connector or design a custom through-hole pogo pin connector. Free samples ship within two weeks.
