The Normally Open Switch Probe F88617B300G900LM (item number 1004233) combines spring-loaded contacting with a defined switching or sensing function. F88617B300G900LM combines electrical contacting with a switching signal so that DUT presence or position can be evaluated directly in the test sequence. In F88617B300G900LM, the normally open function closes the electrical contact at the defined actuation travel, combining contacting with presence or position information. For F88617B300G900LM, spring force is 900 cN at a nominal travel of 4 mm. F88617B300G900LM is rated for 10 A continuous current with a typical contact resistance of 50 mΩ. F88617B300G900LM combines a pitch of 3.5 mm / 138 mil with tip style 17 (Flat stepped) and a tip diameter of 3 mm.
