Beschreibung des Produkts
F77321S180L300 (item number 1001534) is a Basic Contact Probe for repeatable temporary connections between the test system and a test point. With tip style 21 (4-point crown (self-cleaning)), F77321S180L300 combines ICT/FCT use with a geometry intended for pad surfaces and soldered pins where the crown geometry can penetrate residues or oxide layers. F77321S180L300 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. F77321S180L300 operates with 300 cN spring force and 4 mm nominal travel. F77321S180L300 is rated for 10 A continuous current with a typical contact resistance of 25 mΩ. The plunger in F77321S180L300 is made of steel and uses Longtime Gold plating.
