Hydraulic Control Valve Pressure Switch HED8-OA-20 R901106453 OEM
Rexroth Pressure Switch HED8-OA-20
R901106453 Pilot Operated With NBR Seals
Product Description:
Hydro-electric pressure switches of model HED 8 are piston-type pressure switches used to monitor a pressure value in a circuit. As a pressure value is achieved (rising or falling), the HED micro-switch changes state, which can be used as an indicator for the next sequential operation or shutdown. The HED microswitch is not a current carrying device; it is an actuator/sensor.
Potential-free switching of currents from 1 mA to 2.0 A. Small hysteresis, depending on the set switching point. High repetition accuracy < 1% of the set pressure
- Piston type pressure switch
- Micro switch with NC contact/NO contact function
- Subplate mounting
- Adjustment type: Spindle with internal hexagon, without scale, without protective cap
- Without mating connector, connector DIN EN 175301-803
- With NBR seals
