The Bosch Rexroth HED 5 OH-3X/350K14 (R901186323) is a high-performance hydraulic pressure switch designed for precise monitoring and control of system pressure in hydraulic circuits. This piston type pressure switch is renowned for its reliability and accuracy, featuring an adjustable compression spring that allows for specific setting of the desired switching point. The micro switch within this device can handle potential-free switching of currents ranging from milliamps to 2 amps, ensuring versatility in its application. The HED 5 OH-3X/350K14 is equipped with NBR seals and has a maximum pressure rating of 350 bar, making it suitable for high-pressure applications. It boasts a large cubic connector in accordance with DIN EN standards for the electrical connection, which does not include the mating connector. The pressure switch operates on a supply voltage ranging from 24 to 240 V AC/DC, adding to its flexibility across different power systems. This model is particularly noted for its small hysteresis and high repetition accuracy, which is less than 1% of the set pressure, ensuring consistent performance. The sturdy flange connection enhances stability and durability while also simplifying installation. With CE conformity according to the Low Voltage Directive of the EU, as well as CCC and UL certifications (with the exception of the MT version), this product meets rigorous international standards. Designed with careful consideration to longevity, Bosch Rexroth recommends installing the HED 5 OH-3X/350K14 in areas with minimal vibration exposure and protection from hydraulic pressure surges to maximize its lifecycle. Its robust construction and dependable operation make it an ideal choice for various hydraulic applications that require precise pressure monitoring and control.

PRESSURE SWITCH HED 5 OH-3X/350K14

400 bar micro switch with NC contact/NO contact function, device connector DIN EN 175301-803 (large cubic connector)

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.

Unpacked Weight: 0.228 kg

4 pressure ratings Electrical connection with large cubic connector Micro switch with NC/NO contact function Potential-free switching of currents from 1 mA to 2 A

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.
