Beschreibung des Produkts
F81912B0002G2020 (item number 1137519) is a Kelvin Probe for measuring very low resistance values with reduced influence from lead and contact resistance. The separate current and voltage paths in F81912B0002G2020 support four-wire measurements in which lead and contact resistance have minimal influence on the result. For F81912B0002G2020, continuous current ratings for the outer and inner contacts are 10 A / 4 A. F81912B0002G2020 combines a pitch of 12 mm / 472 mil with tip style 50 (Concave with drill hole stepped) and a tip diameter of 0.9 mm. F81912B0002G2020 operates with 1500 cN spring force and 5 mm nominal travel. The plunger in F81912B0002G2020 is made of beryllium copper and is gold-plated.
