Hydro-electric pressure switch Type HED 8

This UL-recognised, CCC-certified piston-type pressure switch from Bosch Rexroth comes in pressure ratings of 50, 100, 200, 350 and 630 bar. It is easy to operate and delivers precise control across a variety of applications.

If the pressure monitored is below the set value, simply use the micro switch as required. The pressure is applied via the nozzle at the piston, which is supported by the spring plate and acts against the continuously adjustable force of the compression spring. The spring plate transmits the movement of the piston onto the micro switch and releases the latter wen the set pressure is reached, switching the circuit on or off, depending on setup.

The mechanical positive stop of the spring plate protects the micro switch in case of a sudden pressure drop from mechanical destruction and, in the case of overpressure, prevents solid compression of the compression spring.
