Beschreibung des Produkts
For contact points inside housings and recesses, F70311B0001R080BSP (item number 1035714) uses a flat plate head at a defined penetration depth. On F70311B0001R080BSP, electrical contact is established only at the intended penetration depth, making the Step Probe suitable for position and presence checks on connectors. On F70311B0001R080BSP, contact geometry is characterized by pin diameter 0.5 mm, plate diameter 1.5 mm, pin length 3 mm. For a pitch of 1.9 mm / 75 mil, spring force is 80 cN at a nominal travel of 3 mm. The continuous-current rating of F70311B0001R080BSP is 4 A. The plunger is made of beryllium copper and is Rhodium-plated.
