Products with Flanges

High-vibration applications call for additional measures to prevent terminal blocks from coming loose from pin strips. Many PTR multi connector systems integrate flanges (product example: AK4551/..FKD-3.5-BASALT GREY), whereby screws are mounted on both sides of the terminal block and screw sockets are mounted on both sides of the pin strip. Screwing these two elements together after the terminal block is inserted in the pin strip guarantees that the terminal block will remain in place. The flange screws may be tightened up to a maximum torque of 0.3 Nm.
