The Normally Open Switch Probe F88506B230G550SM (item number 1009239) combines spring-loaded contacting with a defined switching or sensing function. F88506B230G550SM combines electrical contacting with a switching signal so that DUT presence or position can be evaluated directly in the test sequence. In F88506B230G550SM, the normally open function closes the electrical contact at the defined actuation travel, combining contacting with presence or position information. For F88506B230G550SM, spring force is 550 cN at a nominal travel of 4 mm. F88506B230G550SM is rated for 10 A continuous current with a typical contact resistance of 50 mΩ. F88506B230G550SM combines a pitch of 3.5 mm / 138 mil with tip style 06 (Serrated stepped) and a tip diameter of 2.3 mm.
