As a Basic Contact Probe, F78821S060L165 (item number 1001550) establishes a spring-loaded electrical connection to the test point. With tip style 21 (4-point crown (self-cleaning)), F78821S060L165 combines ICT/FCT use with a geometry intended for pad surfaces and soldered pins where the crown geometry can penetrate residues or oxide layers. F78821S060L165 combines a pitch of 1.27 mm / 50 mil with tip style 21 (4-point crown (self-cleaning)) and a tip diameter of 0.6 mm. F78821S060L165 operates with 165 cN spring force and 6.4 mm nominal travel. F78821S060L165 is rated for 2 A continuous current with a typical contact resistance of 20 mΩ. The plunger in F78821S060L165 is made of steel and uses Longtime Gold plating.
