The 125-PRS2509H from QA Technology's 125-25 Series delivers for loaded board and high current testing. At a 0.125" center and a 0.250" stroke, its stainless steel spring provides high force and lasts up to 300,000 cycles. Its Serrated tip design (#09) ensures stability and side-loading minimization. Expect < 15 mOhms resistance from its precision-engineered tube. The angled plunger tail, a QA Technology innovation, keeps internal contact consistent . Temperature rated from -55°C to 120°C with lubrication.

Questions and Answers

What is the maximum voltage that QA Technology test probes and sockets can carry?
There is no specific upper voltage limit defined for test probes or socket/termination pins. However, the spacing between probes and the dielectric strength of the probe plate must be evaluated. Probe plate materials that absorb moisture should be avoided. Apply test voltage to the fixture or DUT only after the fixture is engaged and the probes are fully compressed against the DUT. Energizing the probes before they make contact can cause arcing, which may damage or melt the probe tips.

Can QA Probes be used for Hipot testing?
Yes. Hipot testing, short for High Potential testing and also known as a Dielectric Withstanding Voltage (DWV) test, subjects a device to a voltage higher than its normal operating level. The purpose is to confirm that the device’s insulation can withstand this elevated voltage without breaking down, ensuring it provides adequate protection against electrical shock. This method is commonly applied to PCBs, transformers, electric motors, finished appliances, cables, and other wired or wireless assemblies.
