Electronic Pressure Switch Element X771.32.0.1.AC.M2 For Hydraulic Filter Systems

The Bosch Rexroth WE-1SP-M12X1 (R928028409) is an advanced electronic switching element designed to enhance mechanical/visual maintenance indicators in hydraulic filter systems. This component easily attaches to existing indicators using a locking ring, ensuring secure installation unaffected by system pressure.

The device monitors back pressure or pressure differential, moving a piston against a spring which shifts a mounted solenoid. The visual pin displays two positions: retracted below nominal pressure and extended when exceeding pressure thresholds. Once extended, the pin maintains position as a system status indicator, even during power loss or pressure drops, thanks to its cold start memory function - requiring manual reset.

Key features include:

• Reed contacts responding to magnetic field changes for precise operation
• Temperature suppression function for reliable performance
• Modular flexibility with cold start signal suppression
• Compatible with various indicator systems (excluding WOS.PA polyamide types)
• Optional mating connectors available (not included)
