Centalic PE75-B-5.5GG Test Probe, Needle Tip, 75mil

The Centalic PE75-B-5.5GG is a spring-loaded in-circuit test probe for fixtures laid out on 1.91 mm (75 mil) centres. It runs in an RE75 receptacle pressed into the probe plate, so worn probes are pulled and replaced without touching the wiring.

The PE75 shares the 75 mil (1.91 mm) body dimensions of the PQ75 but is offered in a higher force band — 5.5, 7.2 and 8 oz against the PQ75's 4 to 7 oz — so it is the family to specify when a 75 mil (1.91 mm) field needs more contact force than the standard range gives. This variant carries the B needle (spear) head on the lightest of those three springs, 5.5 oz (150 gf), concentrating the load on one point to cut through no-clean residue on small pads and vias.
