The Normally Open Switch Probe F88617H450U900SM (item number 1006205) combines spring-loaded contacting with a defined switching or sensing function. F88617H450U900SM combines electrical contacting with a switching signal so that DUT presence or position can be evaluated directly in the test sequence. In F88617H450U900SM, the normally open function closes the electrical contact at the defined actuation travel, combining contacting with presence or position information. For F88617H450U900SM, spring force is 900 cN at a nominal travel of 4 mm. The electrical rating of F88617H450U900SM combines 10 A continuous current with 50 mΩ typical contact resistance. F88617H450U900SM combines a pitch of 3.5 mm / 138 mil with tip style 17H (Synthetic head with slot and metal ring) and a tip diameter of 4.5 mm.
