The Step Probe F73012B0004G110SP (item number 1000578) is a Spring Contact Probe with a disc-shaped contact area for position and presence testing. On F73012B0004G110SP, electrical contact is established only at the intended penetration depth, making the Step Probe suitable for position and presence checks on connectors. F73012B0004G110SP 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 1.27 mm / 50 mil, step diameter 0.9 mm, pin diameter 0.5 mm, pin length 1.1 mm, spring force 110 cN, pointing accuracy ±0.08 mm. The electrical rating of F73012B0004G110SP combines 3 A continuous current with 50 mΩ typical contact resistance. The stepped contact geometry of F73012B0004G110SP makes electrical contact only in the intended installation position and can therefore help detect missing or incorrectly positioned terminals.
