Rexroth HED8OH-2X/50
Hydraulic pressure switch
Rexroth HED8OH-2X/50 Hydraulic Pressure Switch Versatile Fluid Control Viscosity Range 10 To 800 Mm2 /S
The hydro-electric pressure switch type HED 8 is a piston type pressure switch. It consists of a housing, an installation kit with a piston, a compression spring, an adjustment element and a micro switch.
When the pressure to be monitored falls below the set pressure, the micro switch is activated. The pressure is applied through a nozzle onto the piston, which is supported by the spring plate.
The movement caused by the piston activates the micro switch and either switches the electric circuit on or off, depending on how the circuit is set up.
The mechanical positive stop of the spring plate protects the micro switch in case of a sudden pressure drop from mechanical destruction, and in case of overpressure, prevents the compression spring from being squashed.
Notice: To increase the service life, the pressure switch should be mounted with low vibrations and protected from hydraulic pressure surges.
For subplate mounting/pipeline installation, there are 5 pressure ratings with 4 adjustment types.
The product is also in accordance with ISO 16873 for flange
connection and ISO 4401 for vertical stacking element.
The electrical connection comes with large cubic connector and M12
x 1 connector, and the micro switch offers NC/NO contact function
with potential-free switching of currents from 1 mA to 2 A. UL
approval is available for pressure ranges up to 350 bar.

In the field of petroleum and chemical production, pressure relays can monitor pressure changes in containers and pipelines, timely triggering alarm devices or automatic control valves, and ensure the safety and stability of the production process.
In the pharmaceutical field, pressure relays are responsible for real-time monitoring of the pressure of pharmaceutical equipment. If abnormal pressure fluctuations occur, it can quickly take corresponding measures, such as closing valves, starting emergency pumps, etc., to prevent equipment damage and ensure drug quality.
In the field of food processing and packaging, pressure relays can monitor the pressure status of production equipment, ensuring that products are produced and packaged under suitable pressure conditions, thereby improving production efficiency and product quality.
