The Bosch Rexroth HED 5 OH-3X/50K14 (R901182344) is a high-performance hydraulic piston type pressure switch designed to offer reliable monitoring and control for a range of hydraulic applications. This pressure switch features a robust design with an NBR seal, ensuring compatibility with various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, and HFC. The micro switch within the unit can operate with both NC (normally closed) and NO (normally open) contact functions, allowing for potential-free switching of currents ranging from milliamperes to 2 amperes.
With its small hysteresis and high repetition accuracy of less than 1% of the set pressure point, the HED 5 OH-3X/50K14 ensures precise operation. The device's maximum operating pressure is rated at 315 bar and it comes with pressure ratings options of 6, 10, 16, 25, and 50 bar. The electrical connection is facilitated by a large cubic connector according to DIN EN standards without mating connector included.
For added safety and compliance with international standards, this model carries CE marking in accordance with the Low Voltage Directive EU Electrical connector specifications. It also has UL approval and CCC approval (except for MT version), indicating its suitability for various global markets.
The unit's flange connection design allows for easy installation while its weight of approximately 0.8 kg ensures it remains lightweight yet durable. To enhance its lifespan and performance reliability, it is recommended that the HED 5 OH-3X/50K14 be installed in areas with minimal vibrations and protected from hydraulic pressure surges. This Bosch Rexroth pressure switch stands out as a dependable solution for those requiring accurate pressure monitoring in their hydraulic systems.

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.
