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