The Step Probe F73211B0018G150SP (item number 1005267) is a Spring Contact Probe with a disc-shaped contact area for position and presence testing. On F73211B0018G150SP, electrical contact is established only at the intended penetration depth, making the Step Probe suitable for position and presence checks on connectors. F73211B0018G150SP is suited to contacts located in housings, recesses or difficult-to-access areas because its disc head makes contact only at a defined penetration depth. Key mechanical specifications include pitch 2.54 mm / 100 mil, step diameter 1.5 mm, pin diameter 0.65 mm, pin length 5 mm, spring force 150 cN, pointing accuracy ±0.08 mm. F73211B0018G150SP is rated for 5 A continuous current with a typical contact resistance of 20 mΩ. The stepped contact geometry of F73211B0018G150SP makes electrical contact only in the intended installation position and can therefore help detect missing or incorrectly positioned terminals.
