Bosch Rexroth HED8OH-20 200K14 R901099808 Pressure Relay

The Bosch Rexroth R901099808 HED 8 OH-2X/200K14 is a two-channel, piston-type pressure switch that converts hydraulic pressure changes into electrical switching actions, rated for up to 200 bar. Designed for use in hydraulic systems, it provides two independent switching elements (2X) with potential-free outputs, enabling dual-point monitoring or redundancy. Each channel uses a micro switch with both normally closed and normally open outputs, allowing isolated signaling of pressure events without a shared supply. The part is identified as HED 8 OH-2X/200K14 with the Rexroth catalog number R901099808, making it suitable for integration where precise hydraulic pressure thresholds must trigger electrical signals for control or safety interlocks.
