The Bosch Rexroth HED 8 OH-2X/100K14S (R901108239) is a high-precision hydroelectric pressure switch designed for monitoring and controlling hydraulic pressure in various applications. This piston-type pressure switch features a robust housing and includes an installation kit containing a piston, compression spring, adjustment element, and micro switch. The device operates by applying the monitored pressure to the piston through a nozzle. The piston, supported by a spring plate, counters the adjustable force of the compression spring. When the monitored pressure falls below the set value, the movement of the piston actuates the micro switch, which either opens or closes an electrical circuit based on its configuration. A mechanical positive stop ensures protection for the micro switch against damage from sudden pressure drops and prevents solid compression of the spring in overpressure situations. The HED 8 series offers various models including HED OHXK(S), HED OPXKA(S), and HED OAXKKW(S) for diverse mounting options such as subplate mounting, pipeline installation, flange connection compliant with ISO standards, or as vertical stacking elements alongside sandwich plates also adhering to ISO specifications. Adjustment types provided with this model include spindle with or without protective cap, spindle with scale (with or without protective cap), rotary knob with scale, and lockable rotary knob with scale. Electrical connections can be made via valve plug-in connectors or large cubic connectors with M12x1 threading. The micro switch supports both normally closed (NC) and normally open (NO) contact functions and can handle potential-free switching of currents ranging from mA to A. Additionally, it holds UL approval for pressure ranges up to bar. For optimal performance and longevity of the Bosch Rexroth HED 8 OH-2X/100K14S pressure switch, it should be installed in areas with minimal vibrations and shielded from hydraulic shocks.
