The Normally Open Switch Probe F87511B100G135L (item number 1009302) combines spring-loaded contacting with a defined switching or sensing function. F87511B100G135L combines electrical contacting with a switching signal so that DUT presence or position can be evaluated directly in the test sequence. In F87511B100G135L, the normally open function closes the electrical contact at the defined actuation travel, combining contacting with presence or position information. For F87511B100G135L, spring force is 135 cN at a nominal travel of 4 mm. F87511B100G135L is rated for 5 A continuous current with a typical contact resistance of 65 mΩ. F87511B100G135L combines a pitch of 2.54 mm / 100 mil with tip style 11 (Spherical) and a tip diameter of 1 mm.
