• Conventional probe designed for high current testing.
• 0.187 center and 0.250 full stroke probe, part of QA Technology's 187-25 Series.
• High Spring Force (SF) made of stainless steel material with a 300,000 cycle life.
• Cup tip style (#22) can be used for extremely long leads.
• Tube material "H" high conductivity proprietary alloy/gold plated improves wear properties and offers < 15 mOhms resistance.

The 187-PRH2522H, part of QA Technology's 187-25 Series, is a conventional probe designed for high current testing. Configured ata 0.187" center with a 0.250" stroke, you get high spring force backed by a 300,000-cycle lifespan. A Cup tip (#22) provides the contact geometry you need for long leads or for collecting dust and contamination from the unit under test (UUT). Low < 15 mOhms resistance ensures signal integrity throughout the tube. Factory lubrication maximizes cycle life and QA Technology's signature angled plunger improves biasing ensuring consistent electrical contact. Safe for use between -55°C and 120°C.

Questions and Answers

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.

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.
