Bosch Rexroth HEDE10-3X/400/1/-GA-K35-V Electronic Pressure Switch – 400 Bar

General

The Bosch Rexroth HEDE10-3X/400/1/-GA-K35-V (R901433084) 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 400 bar, one configurable switching output and one analog output. The analog output supports selectable 0–10 V DC or 4–20 mA signals, while the integrated digital display provides convenient monitoring of pressure values and device parameters. IO-Link communication enables additional transmission of pressure measurements and diagnostic information to connected automation systems.

The device features a male G1/4 hydraulic connection, a four-pole M12 x 1 A-coded electrical connector and a 24 V DC nominal power supply. Its stainless steel wetted components, FKM sealing elements and integrated throttle element provide reliable operation in demanding industrial hydraulic environments.
