Electronic Test Probe Pogo Pin PC50 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 PC50 series here. Its test center is 50 mil, namely 1.27 mm. The diameter is 0.78 mm and the total length is 43.2 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, SC, SW and CRW, to fit each test probe. For details, please check below parameters. Technical Specifications Recommended Minimum Center: 1.27 mm (50 mil) Current Rating: 3 Amps, continuous Contact Resistance: 60 milliohms Mounting Hole Size: 1 mm Full Stroke: 6.4 mm Rated Stroke: 4.3 mm Spring Force: 100/110/150/200 gf (3.6/4/5.4/7.2 oz) Materials Receptacle: Phosphor Bronze, Gold Plated Contact Barrel: Phosphor Bronze, Gold Plated Spring:�  Music Wire, Gold Plated Plunger: SK4, Nickel Plated or Gold Plated Company Information Centalic Technology Development Ltd. was founded in 1980.
