The Bosch Rexroth HED 5 OH-3X/350K14V (R901227564) is a high-precision hydraulic pressure switch designed for reliable monitoring and control of pressure systems. This piston-type pressure switch features a micro switch with both normally closed (NC) and normally open (NO) contact functions, ensuring versatile application across various circuit setups. The robust design includes FKM seals for compatibility with a range of hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR.
This model boasts exceptional hysteresis characteristics and high repetition accuracy of less than 1% of the set pressure value. It has a maximum operating pressure rating of 350 bar and offers selectable pressure ratings including 50, 100, 200, 250, and 315 bar to suit different requirements. The device is equipped with a large cubic DIN EN electrical connector that supports potential-free switching of currents ranging from mA to .5 A without any mating connector included.
The HED 5 OH-3X/350K14V comes with a supply voltage range between 24 to 240 V AC/DC and has been built to conform with international standards including CE according to the Low Voltage Directive EU Electrical connector Connector pole PE and is also recognized by CCC and UL certifications (except for the MT version). Its flange connection design ensures secure installation while its light weight of .52 kg facilitates easy handling.
For optimal performance and longevity, it is recommended that the pressure switch be installed in an environment with minimal vibrations and protected from hydraulic pressure surges. The product group ID associated with this model are 45060, 45061, 45062, 45063, and 45064. Users can expect consistent operation due to the careful construction comprising housing components that house the piston mechanism supported by a spring plate which actuates the micro switch upon reaching designated pressure levels.

Hydro-electric pressure switches of type HED 5 are piston type pressure switches.
They basically consist of housing (1), installation kit with piston (2), compression spring (3), adjustment element (4) and micro switch (5)
The pressure to be monitored acts on the piston (2)
The latter is supported by the spring plate (6) and acts against the continuously adjustable force of the compression spring (3).
The spring plate (6) transmits the movement of the piston (2) onto the micro switch (5). This switches the electric circuit on or off, depending on the circuit set-up.
Notice:
In order to increase the life cycle, the pressure switch should be mounted with low vibrations and protected from hydraulic pressure surges.
Switching pressure differential (measured with HLP46, ϑOil = 40 ±5 °C)
Pressure rating 50 bar
Pressure rating 100 bar
Pressure rating 200 bar
Pressure rating 350 bar
Notice:
The switching pressure differential may increase within the course of the life cycle due to the deterioration of the oil quality and the number of load cycles.
