Bosch Rexroth R901108236 Pressure Relay

R901108236 is a Bosch Rexroth pressure switch in the HED 8 family, designated HED 8 OH-2X/350K14AS. This dual-switch device contains two switching elements in a single compact housing, enabling two independent pressure-triggered signals for interlocks or control circuits in hydraulic systems. It monitors system pressure and provides electrical actuation when preset thresholds are reached, supporting safety and automation functions in equipment such as hydraulic presses, injection molding machines, and other Rexroth-driven machinery. The part number and variant naming (OH-2X/350K14AS) identify its dual-switch configuration within Rexroth’s valve-sensor ecosystem and its intended electrical interface for integration with Bosch Rexroth control architectures. Intended use cases include pressure-based sequencing, safety interlocks, and two-channel monitoring where reliable, repeatable actuation at a specified pressure is required, all built to align with Bosch Rexroth engineering standards for industrial automation systems.
