Beschreibung des Produkts
The Basic Contact Probe F70321S078L150 (item number 1017942) is a spring-loaded probe for temporary electrical contact with test points. With tip style 21 (4-point crown (self-cleaning)), F70321S078L150 combines ICT/FCT use with a geometry intended for pad surfaces and soldered pins where the crown geometry can penetrate residues or oxide layers. The design combines a pitch of 1.9 mm / 75 mil with tip style 21 (4-point crown (self-cleaning)) and a tip diameter of 0.78 mm. F70321S078L150 operates with 150 cN spring force and 4.3 mm nominal travel. F70321S078L150 is rated for 4 A continuous current with a typical contact resistance of 20 mΩ. The plunger in F70321S078L150 is made of steel and uses Longtime Gold plating.
