Beschreibung des Produkts
F80521B0004G250 (item number 1056956) belongs to the Kelvin Probe range for four-wire measurements and demanding electrical test tasks. The separate current and voltage paths in F80521B0004G250 support four-wire measurements in which lead and contact resistance have minimal influence on the result. Continuous current ratings for the outer and inner contacts are 2.5 A / 0.5 A. The design combines a pitch of 2.2 mm / 87 mil with tip style 55 (Concave stepped (self-cleaning)) and a tip diameter of 1.18 mm. Spring force is 200 cN at a nominal travel of 2 mm. The plunger in F80521B0004G250 is made of beryllium copper and is gold-plated.
