Beschreibung des Produkts
As a Basic Contact Probe, F77312B300G300 (item number 1001524) establishes a spring-loaded electrical connection to the test point. With tip style 12 (Spherical stepped), F77312B300G300 combines ICT/FCT use with a geometry intended for clean contact surfaces where marking or scratching should be minimized. F77312B300G300 combines a pitch of 3.5 mm / 138 mil with tip style 12 (Spherical stepped) and a tip diameter of 3 mm. For F77312B300G300, spring force is 300 cN at a nominal travel of 4 mm. The electrical rating of F77312B300G300 combines 10 A continuous current with 25 mΩ typical contact resistance. The plunger in F77312B300G300 is made of beryllium copper and is gold-plated.
