The Bosch Rexroth HED 5 OH-3X/100K14 (R901185727) is a high-precision hydraulic pressure switch designed for reliable monitoring and control of pressure in hydraulic systems. This piston type pressure switch is characterized by its robust construction and features a bar micro switch with both normally closed (NC) and normally open (NO) contact functions, allowing for the potential-free switching of currents ranging from milliamps to 2 amps. The device ensures small hysteresis and high repetition accuracy, which is less than 1% of the set pressure, contributing to the consistent performance of the system it's integrated into. The HED 5 OH-3X/100K14 comes with an NBR seal and offers flange connection capabilities, making installation straightforward. It has a maximum pressure rating of 315 bar and does not include a mating connector; however, it does have a large cubic connector conforming to DIN EN standards. The electrical connection is described as a connector with pole + PE according to DIN EN, ensuring secure and reliable electrical integration. This model has been designed for use with various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, and HFC. It conforms to CE standards according to the Low Voltage Directive EU Electrical connector specifications. Moreover, it boasts certifications such as CE, CCC (except for MT version), and UL approval. The product group ID includes numbers 4 through 8 indicating its categorization within Bosch Rexroth's product offerings. With an operating voltage range from 24 to 240 V AC/DC and a weight of approximately 0.5 kg, this pressure switch provides versatility in application while maintaining durability. In summary, the Bosch Rexroth HED 5 OH-3X/100K14 offers precise control for hydraulic systems demanding high accuracy in pressure monitoring with its durable design and comprehensive certification compliance ensuring reliability in various operational conditions.

PRESSURE SWITCH HED 5 OH-3X/100K14

350 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: 0.2355 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.
