The Twist Proof Probe F75514B300G300E13 (item number 1009449) keeps its contact tip in a defined rotational orientation. The twist-proof design of F75514B300G300E13 keeps the contact geometry in a defined orientation and is therefore suited to direction-sensitive connector contacting. The twist-proof design of F75514B300G300E13 is useful in connector testing when elongated contours, contact tongues or direction-dependent tip geometries must remain precisely aligned. Tip style 14 (4-point crown stepped (self-cleaning)) has a diameter of 3 mm. For F75514B300G300E13, spring force is 300 cN at a nominal travel of 5.6 mm. Pointing accuracy for F75514B300G300E13 is specified as ±0.1 mm.
