The Twist Proof Probe F75583B0001G300E18 (item number 1011656) keeps its contact tip in a defined rotational orientation. On F75583B0001G300E18, tip style 83 (SpadeØ > plungerØ) supports twist-proof contacting of connector elements whose orientation must be maintained in the test fixture. The twist-proof design of F75583B0001G300E18 is useful in connector testing when elongated contours, contact tongues or direction-dependent tip geometries must remain precisely aligned. On F75583B0001G300E18, tip style 83 (SpadeØ > plungerØ) has a diameter of 2.5 mm. For F75583B0001G300E18, spring force is 300 cN at a nominal travel of 5.6 mm. Pointing accuracy for F75583B0001G300E18 is specified as ±0.1 mm.
