The “K4” series adjustable pressure switches allow to open or close an electric circuit upon reaching predetermined pressure value. The preset pressure is found by rotating the external screw located at the centre of the instrument, clockwise to increase and vice-versa to decrease the pressure set point value. The screw is protected with a plug. Mechanical stops protect both the spring and the micro-switch from over pressurization. Technical features: Body: 24 mm hexagonal in zinc-plated carbon steel Assembly: in every position Working temperature: from - 20°C to + 80°C Switching frequency: 90 cycles/min Switching accuracy: ± 5% of the end of scale at 20°C Operating point: adjustable through a central screw Fixed hysteresis value: - membrane execution ~ 10% of end of scale - piston execution ~ 20% of end of scale - Y execution ~ 25% of end of scale Weight: 0,06 Kg Mechanical life: 106 cycles at 70bar (1000 psi) at20°C Electric Features: - Maximum load: 0.5 Ampère at 250 Volt AC (see also dedicated page) - Electric protection according to DIN 40050: IP54 with P1 rubber protection cap (see picture) - Simple contact
