IMI Norgren 18D is an electromechanical pressure switch for industrial hydraulic systems. It works with neutral self-lubricating fluids – hydraulic and lubricating oil, light fuel. The actuator is a piston with a soft seal.
Features
- Working pressure range 5…70 bar (72…1015 psi)
- Fixed hysteresis: 10.5 bar at the bottom and 15 bar at the top of the range
- Port 1/4″ NPT, electrical connection DIN EN 175301-803 form A (IP65)
- SPDT microswitch with gold-plated contacts, UL and CSA certified
- Mechanical life – 107 cycles, up to 100 cycles/min
- Vibration resistance 15 g, repeatability ±4 %
- Medium viscosity up to 1000 mm²/s, temperature -25…+80 °C
- Any mounting position; weight 0.2 kg
Applications
Pressure monitoring in the hydraulic circuits of presses, machine tools, mobile equipment and power units: signalling that a set pressure has been reached, pump protection, cycle interlock on pressure loss.
Switching capacity
Maximum continuous current 0.1 A at 30/48/125/250 V (AC) and 30 V (DC), minimum voltage 6 V. Electrical life – over 2×105 cycles.
