QA Technology 125-PRG2509S Probe, 0.125 Center, 0.250 Full Stroke, Serrated, Standard SF, 100-40 Series

• 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 "G" nickel silver or phos bronze/od gold plated improves wear properties and offers < 20 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-PRG2509S, part of QA Technology's 125-25 Series is a conventional probe designed for loaded board and high current testing. This probe offers 0.125" center spacing and 0.250" full stroke capability, you get standard spring force backed by a 1,000,000-cycle lifespan. A Serrated tip (#09) provides the contact geometry you need for stability on a lead or post. Low < 20 mOhms resistance ensures signal integrity throughout the tube. Factory lubrication and QA Technology's signature angled plunger design maximize cycle life. 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.
