Beschreibung des Produkts
For contact points inside housings and recesses, F73311B1048G150SP1 (item number 1009023) uses a flat plate head at a defined penetration depth. On F73311B1048G150SP1, 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 1.8 mm, plate diameter 4 mm, pin length 3 mm. On F73311B1048G150SP1, a pitch of 4 mm / 157 mil is combined with 150 cN spring force and 4 mm nominal travel. The continuous-current rating of F73311B1048G150SP1 is 10 A. The plunger in F73311B1048G150SP1 is made of beryllium copper and is gold-plated.
