While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth HED 8 OP-2X/100K14S (R901106509) is a high-performance hydraulic pressure switch designed for precise monitoring and control of hydraulic systems. It features a piston type pressure switch mechanism that includes a housing, piston, compression spring, and an adjustable element, ensuring accurate operation and reliable performance. This model is equipped with a micro switch that provides normally closed (NC) or normally open (NO) contact functions, enabling potential-free switching of currents ranging from mA to 0.5A. The HED 8 OP-2X/100K14S boasts high repetition accuracy of less than 1% of the set pressure and a small hysteresis for consistent switching points. It is designed for subplate mounting with NBR seals suitable for hydraulic fluids such as HL, HLP, HLPD, HVLP, and HVLPD. The device connector complies with DIN EN standards for easy integration into existing systems. This model has a wide range of applications due to its various adjustment types including spindle with or without protective cap, and rotary knob options. With its robust construction and maximum operating pressure of up to 630 bar, it can handle pressure ratings of 6, 10, 25, 100, and 200 bar. Additionally, the HED 8 OP-2X/100K14S features multiple certifications including CE according to Low Voltage Directive EU Electrical connector Connector pole PE Type of connection Subplate mounting Connection diagram Subplate mounting Supply voltage from 24 bis to 240 V AC/DC. To ensure longevity and optimal performance, it is recommended to install the pressure switch in areas with minimal vibrations and protect it from hydraulic surges. The Bosch Rexroth HED series also includes variants like the HED 8 OHXK/S and OAXKKW/S models catering to different installation needs such as pipeline installation or flange connections according to ISO standards.

The hydro-electric pressure switch type HED 8 is a piston type pressure switch. It basically comprises of housing (1), installation kit with piston (2), compression spring (3), adjustment element (4) and micro switch (5).

If the pressure to be monitored is below the set value, the micro switch (5) is operated. The pressure to be monitored is applied via the nozzle (7) at the piston (2). The piston (2) 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) and releases the latter when the set pressure is reached. This switches the electric circuit on or off, depending on the circuit set-up. The mechanical positive stop of the spring plate (6) protects the micro switch (5) in case of a sudden pressure drop from mechanical destruction and, in case of overpressure, prevents solid compression of the compression spring (3).

Notices:

In order to increase the life cycle, the pressure switch should be mounted with low vibrations and protected from hydraulic pressure surges.
