QA Tech 100-PRN2506S, Star Tip, 100mil

The QA Technology 100-PRN2506S is a conventional spring probe from the 100-25 series: 100 mil (2.54 mm) centres, 0.250 in (6.35 mm) full stroke, 0.167 in (4.24 mm) working stroke. The 100 mil (2.54 mm) pitch is the default for in-circuit and functional test fixtures, and this series carries QA Technology's widest choice of tip styles and spring forces, so it is usually where a fixture design starts.

In the ordering code, N is the tube material — nickel silver with no finish. It is the economy option, and the trade-off is electrical: under 165 mΩ average resistance and 10.2 A at 120 °C, against under 10 mΩ and 19.8 A for the gold-plated H tube. Specify N for straightforward continuity and digital signal probing; move up to P, V, G or H tubes where contact resistance is in the measurement path or the probe carries current. 06 is the 90° star tip at ø0.062 in (1.57 mm), a multi-point head that bites through flux residue and stays tolerant of landing error — the general-purpose ICT tip. S is the standard spring, 5.5 oz (156 g / 1.53 N) at working stroke, rated for a million cycles.
