The Normally Open Switch Probe F86311B050G150 (item number 1039841) combines spring-loaded contacting with a defined switching or sensing function. F86311B050G150 combines electrical contacting with a switching signal so that DUT presence or position can be evaluated directly in the test sequence. In F86311B050G150, the normally open function closes the electrical contact at the defined actuation travel, combining contacting with presence or position information. For F86311B050G150, spring force is 150 cN at a nominal travel of 4 mm. F86311B050G150 is rated for 2 A continuous current with a typical contact resistance of 65 mΩ. F86311B050G150 combines a pitch of 1.9 mm / 75 mil with tip style 11 (Spherical) and a tip diameter of 0.5 mm.
