The Normally Open Switch Probe F87505B180G135 (item number 1001712) combines spring-loaded contacting with a defined switching or sensing function. F87505B180G135 combines electrical contacting with a switching signal so that DUT presence or position can be evaluated directly in the test sequence. In F87505B180G135, the normally open function closes the electrical contact at the defined actuation travel, combining contacting with presence or position information. For F87505B180G135, spring force is 135 cN at a nominal travel of 4 mm. F87505B180G135 is rated for 5 A continuous current with a typical contact resistance of 65 mΩ. F87505B180G135 combines a pitch of 2.54 mm / 100 mil with tip style 05 (Concave stepped) and a tip diameter of 1.8 mm.
