Gold Plated Pogo Pin PCBA Probe PE75(PO) Series for In-circuit Test 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 PE75(PO) series here. Its test center is 75 mil. The diameter is 1 mm and the total length is 33 mm. Various tip styles, for example, A, B, U, H, K, L, BK, etc., are available for test probes. For details, please check below parameters.
