This is a male insert for a Harting size 24B connector, featuring axial screw termination for conductors with a cross-section of 16 to 35mm². It is used to terminate power or signal conductors within heavy-duty industrial connector housings, forming the mating contact element for connections requiring larger cable cross-sections. Such inserts are typically fitted into rectangular connector housings on machinery or panels where reliable, high-current or heavy-gauge wiring connections are required.
