Digital tilt switch SWR14X

dual-axis1-axisprogrammable

Product Introduction
The SWR14X/SWR14D is a digital tilt switch designed for safety-critical leveling and platform-stabilization applications. It integrates a passive relay output and RS232 serial output, allowing configurable alarm thresholds and straightforward interfacing with control systems. When the tilt angle exceeds the programmed limit the relay contact (selectable NO/NC, 1 A drive current) activates and can directly actuate solenoid valves for hydraulic leveling jacks. Typical applications include construction machinery, aerial work platforms and other mobile equipment requiring automatic leveling.
