Beschreibung des Produkts
F73112B9025G110SP (item number 1028227) is a Step Probe for defined contacting of recessed or housing-guided electrical contacts. On F73112B9025G110SP, 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 0.4 mm, plate diameter 1.5 mm, pin length 3 mm. For a pitch of 2.4 mm / 94 mil, spring force is 110 cN at a nominal travel of 2 mm. The continuous-current rating of F73112B9025G110SP is 5 A. The plunger in F73112B9025G110SP is made of beryllium copper and is gold-plated.
