As a Basic Contact Probe, F77221S130L300 (item number 1001569) establishes a spring-loaded electrical connection to the test point. With tip style 21 (4-point crown (self-cleaning)), F77221S130L300 combines ICT/FCT use with a geometry intended for pad surfaces and soldered pins where the crown geometry can penetrate residues or oxide layers. F77221S130L300 combines a pitch of 2.54 mm / 100 mil with tip style 21 (4-point crown (self-cleaning)) and a tip diameter of 1.3 mm. F77221S130L300 operates with 300 cN spring force and 4 mm nominal travel. The electrical rating of F77221S130L300 combines 5 A continuous current with 25 mΩ typical contact resistance. The plunger in F77221S130L300 is made of steel and uses Longtime Gold plating.
