Meet the 100-PRH2553U, a conventional probe from QA Technology's 100-25 Series. Configured at 0.100" center with a 0.250" stroke, it delivers ultra spring force through musical wire construction, rated for 10,000 cycles. The Chisel tip (#53) provides the highest penetrating pressure. The tube construction keeps resistance < 15 mOhms while maximizing wear life. QA Technology's angled plunger tail design maintains consistent contact between cycles. Operating range: -55°C to 120°C (up to 204°C without lubrication for SS springs).

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.
