QA Technology 100-PRP2529X Probe, 250 Stroke, Serrated Tip, Extra Spring Force, 100-25 Series

• 0.100" (2.54 mm) center spacing, part of QA Technology’s 100-25 Series designed for PCBs.
  
• 0.250" (6.35 mm) full stroke, for in‑circuit and functional (ICT/FCT) testing.
  
• Extra spring Force (SF) made of of high-strength music wire (MW) and with a 1,000,000 cycle life.
  
• Serrated (Tip #29) with 0.077 diameter in heat treated BeCu/gold plated over nickel.
  
• Nickel silver/ID precious metal clad tube providing < 15 mOhms average resistance.
  
• Working Temperature Range: -55°C to 120°C with lubrication. Stainless steel (SS) springs can be used up to 204°C without lubrication.

The QA Technology 100-PRP2529X is a test probe with an elevated spring‑force from the 100-25 Series, built for reliable in‑circuit testing (ICT) and functional testing (FCT) on loaded circuit boards. The series’ proprietary high‑conductivity alloys and platings allow it to handle greater electrical currents than standard probes. For applications requiring stability on a lead or post and reduced side‑loading, a serrated tip such as the #29 is a good choice, but has a limited ability to penetrate contamination.

About QA Probes
QA Technology's patented probe design features an angled plunger tail for improved biasing ensuring consistent electrical contact between the internal sliding surfaces of the plunger and probe. They are also lubricated to maximize cycle life and performance. Unlubricated probes (option N) are available if required. Removing lubrication greatly reduces cycle life and should only be used in applications outside of the working temperature range.
