Bosch Rexroth HEDE10-3X/250/1/-GI-K35-0 Electronic Pressure Switch – 250 Bar

General

The Bosch Rexroth HEDE10-3X/250/1/-GI-K35-0 (R901425474) is an electronic hydraulic pressure switch designed for accurate pressure monitoring and control in industrial hydraulic systems. It uses an integrated thin-film measuring cell to measure hydraulic pressure and convert the measured values into electrical signals for monitoring, automation and process control applications.

This electronic pressure switch features a pressure measuring range of 0 to 250 bar, one configurable switching output and one analog output. The analog output supports selectable 0–10 V or 4–20 mA signals, while the integrated digital display provides convenient monitoring of pressure values and device parameters. IO-Link communication enables the transmission of pressure measurements and diagnostic information to connected automation systems.

The device features an internal G1/4 hydraulic connection, a four-pole M12 x 1 A-coded electrical connector and an 18–30 V DC operating voltage. Its stainless steel wetted components, integrated throttle element and compact construction make it suitable for demanding industrial hydraulic applications.
