The Basic Contact Probe F77328B230G300 (item number 1001535) is a spring-loaded probe for temporary electrical contact with test points. With tip style 28 (4-point crown stepped), F77328B230G300 combines ICT/FCT use with a geometry intended for pad surfaces and soldered pins where the crown geometry can penetrate residues or oxide layers. F77328B230G300 combines a pitch of 3.5 mm / 138 mil with tip style 28 (4-point crown stepped) and a tip diameter of 2.3 mm. F77328B230G300 operates with 300 cN spring force and 4 mm nominal travel. The electrical rating of F77328B230G300 combines 10 A continuous current with 25 mΩ typical contact resistance. The plunger in F77328B230G300 is made of beryllium copper and is gold-plated.
