QA Technology 156-PRN2509S Probe, 0.156 Center, 0.250 Full Stroke, Serrated, Standard SF, 156-25 Series

• Conventional probe designed for high current testing.
• 0.156 center and 0.250 full stroke probe, part of QA Technology's 156-25 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 "N" nickel silver/no finish improves wear properties and offers < 375 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 156-PRN2509S is a conventional probe designed for high-current testing in QA Technology's 156-25 Series. At a 0.156" center and a 0.250" stroke, the standard force musical wire spring ensures 1,000,000 cycles of dependable operation. Equipped with a Serrated tip (#09), it's ready for the job of minimizing side-loading. Internally, the tube maintains < 375 mOhms resistance for accurate measurements. Thanks to QA Technology's patented angled plunger tail for improved biasing, you get reliable electrical contact every time. Works from -55°C to 120°C, or up to 204°C for unlubricated stainless steel 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.
