The Step Probe F73012B0009G110SP (item number 1020382) is a Spring Contact Probe with a disc-shaped contact area for position and presence testing. On F73012B0009G110SP, electrical contact is established only at the intended penetration depth, making the Step Probe suitable for position and presence checks on connectors. F73012B0009G110SP 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 1.3 mm, pin diameter 0.8 mm, pin length 2.6 mm, spring force 110 cN, pointing accuracy ±0.08 mm. F73012B0009G110SP is rated for 3 A continuous current with a typical contact resistance of 50 mΩ. The stepped contact geometry of F73012B0009G110SP makes electrical contact only in the intended installation position and can therefore help detect missing or incorrectly positioned terminals.
