Gold Plated Pogo Pin Spring-loaded Test Probe P078 for PCBA Inspection

Gold Plated Pogo Pin Spring-loaded Test Probe P078 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 P078-BK-388 series here. Its barrel diameter is 0.78 mm and the total length is 38.8 mm.

The barrel of this pogo pin is made from phosphor bronze plated with nickel. The plunger is made from SK4 plated with nickel and gold. The inner spring is made from music wire plated with gold and nickel. This test probe could withstand the current up to 3 Amps. The typical maximal contact resistance is about 50 milliohms.

The plunger can be pressed at a distance of up to 9 mm. But it is better to be pressed at a distance of 6.25 mm at most in working environments. Otherwise, the spring will probably be damaged severely under constant pressure. When the plunger is pressed at a distance of 6.25 mm, the loaded force is about 200 gf, which fluctuates to a tolerance.

For details, please check below parameters.
