Beschreibung des Produkts
The Step Probe F73112B0021G110SP (item number 1024780) is designed for position and presence checks on contacts located in connector housings, recesses or other difficult-to-access areas. On F73112B0021G110SP, electrical contact is established only at the intended penetration depth, making the Step Probe suitable for position and presence checks on connectors. Contact geometry is characterized by pin diameter 0.65 mm, plate diameter 1.4 mm, pin length 4.5 mm. On F73112B0021G110SP, a pitch of 2.4 mm / 94 mil is combined with 150 cN spring force and 3.5 mm nominal travel. For F73112B0021G110SP, the specified continuous current is 5 A. The plunger in F73112B0021G110SP is made of beryllium copper and is gold-plated.
