As a Basic Contact Probe, F77321S180L150 (item number 1001533) establishes a spring-loaded electrical connection to the test point. With tip style 21 (4-point crown (self-cleaning)), F77321S180L150 combines ICT/FCT use with a geometry intended for pad surfaces and soldered pins where the crown geometry can penetrate residues or oxide layers. F77321S180L150 combines a pitch of 3.5 mm / 138 mil with tip style 21 (4-point crown (self-cleaning)) and a tip diameter of 1.8 mm. F77321S180L150 operates with 150 cN spring force and 4 mm nominal travel. The electrical rating of F77321S180L150 combines 10 A continuous current with 25 mΩ typical contact resistance. The plunger in F77321S180L150 is made of steel and uses Longtime Gold plating.
