P125B Spring Test Probes — 100 pcs Key benefits Precision fit: Manufactured with advanced computer-controlled machining for dimensional accuracy up to 0.02 mm, ensuring consistent contact and repeatable test results. Reliable conductive testing: The P125B design provides stable, spring-loaded contact for reliable electrical connection during inspections and automated tests. Versatile application: Works with pins, pin headers, and solder joints on PCBs — including boards with light contamination — to improve contact reliability without changing test procedures. Ready-to-use package: 100 probes per pack to support fixture building, maintenance, or high-volume testing needs. What this probe solves Reduces intermittent or false readings caused by poor contact on contaminated pads or pins by providing consistent, controlled contact force. Simplifies test fixture assembly and maintenance by supplying uniform probes sized to tight tolerances. Improves throughput and repeatability for bench and automated testing by delivering predictable mechanical and electrical performance. Key attributes Model: P125B Function: Spring-loaded test probe (pogo-style) for conductive testing Tolerance: Dimensional accuracy up to 0.02 mm Performance: Stable contact and durable construction designed for repeated insertion cycles Quantity: 100 pieces per package Compatibility: PCB testing, pin headers, connectors, solder joints and similar contact points Typical applications In-circuit testing and functional tests of assembled PCBs where reliable contact to pins or pads is required. Bed-of-nails or custom test fixtures for production and QA environments needing consistent probe spacing and repeatability. Manual or automated troubleshooting and inspection of connectors, pin headers, and solder joints on slightly contaminated boards. Package contents 100 x P125B spring test probes Use these probes when you need precise, repeatable conductive contact in test fixtures or inspection setups. The P125B units are supplied in a bulk pack to support fixture construction and ongoing testing operations.
