M12x1 connector, 4-pole available on request (only 24 V DC) (M12x1 cable socket available on request) (see ordering information for cable sockets) Special solutions possible on request RESET DIFFERENTIAL PRESSURE 1. Standard seal (normal version): The hysteresis achieved during continuous operation is approx. 7-12 % of the final value at a set pressure of approx. 60-70 % of the max. adjustable switching pressure. Example: In the case of a DS-307-100 pressure switch with a pressure range of 10-100 bar, a hysteresis of approx. 7-12 bar is achieved at a set pressure of 70 bar. 2. Special...
