• Conventional probe designed for loaded board and high current testing.
• 0.125 center and 0.250 full stroke probe, part of QA Technology's 125-25 Series.
• Standard Spring Force (SF) made of musical wire material with a 1,000,000 cycle life.
• Serrated tip style (#09) for stability on a lead or post and to minimize side-loading but has limited contamination penetration.
• Tube material "S" high conductivity proprietary alloy/silver plated improves wear properties and offers < 15 mOhms resistance.
• Working temperature range of -55°C to 120°C with lubrication. SS springs can be used up to 204°C without lubrication.

The 125-PRS2509S is a in-circuit (ICT) and functional (FCT) probe in QA Technology's 125-25 Series lineup. Featuring a 0.125" center paired with 0.250" stroke, it delivers standard spring force through musical wire construction, rated for 1,000,000 cycles. The Serrated tip (#09) handles your lead or post targets with stability. The tube construction keeps resistance < 15 mOhms while maximizing wear life. QA Technology's angled plunger tail design maintains consistent electrical contact between the internal sliding surfaces of the plunger and probe. 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.
