The Normally Open Switch Probe F87517B180G300 (item number 1003090) combines spring-loaded contacting with a defined switching or sensing function. F87517B180G300 combines electrical contacting with a switching signal so that DUT presence or position can be evaluated directly in the test sequence. In F87517B180G300, the normally open function closes the electrical contact at the defined actuation travel, combining contacting with presence or position information. For F87517B180G300, spring force is 300 cN at a nominal travel of 4 mm. F87517B180G300 is rated for 5 A continuous current with a typical contact resistance of 65 mΩ. F87517B180G300 combines a pitch of 2.54 mm / 100 mil with tip style 17 (Flat stepped) and a tip diameter of 1.8 mm.
