Test Probe Pogo Pin PL50 Series for PCBA Inspection In-circuit test probes are mainly used for testing electrical performance of in-circuit components on PCB and the connection between circuit networks. It could quantitatively measure components such as resistors, capacitors, inductors, crystal oscillators, and perform functional tests of diodes, triodes, optocouplers, transformers, relays, operational amplifiers, power supply modules and integrated circuits. We will introduce in-circuit test probe PL50 series here. Its test center is 50 mil, namely 1.27 mm. The diameter is 0.68 mm and the total length is 27.53 mm. Various tip styles, for example, H, S, T, E, C, U, G, etc., are available for test probes. There are roughly four types of receptacles, namely CR, VCR, SC, VSC, CRW and VCRW, to fit each test probe. For details, please check below parameters.
