About This Product
The PH-18 High Current Test Probe is designed for demanding electronic and electrical testing applications requiring strong contact pressure, stable conductivity, and reliable repeated operation.
With a 3.5 mm mounting hole, 13 mm full travel, and approximately 300g spring force, the PH-18 provides consistent contact with terminals, connectors, PCB test points, battery contacts, and wiring harness components. The probe is rated for 5A current with approximately 50 mΩ contact resistance.
Its robust construction and long spring-loaded travel make it suitable for ICT/FCT fixtures, automated test equipment, automotive electronics, and production-line testing.
