Dual-axis tilt switch LCA series

1-axiswith alarmwith relay output

Product Description
LCA341 / LCA342 series is a low-cost tilt switch developed by RION for applications such as level safety alarming and platform inclination monitoring. It integrates a relay output with a preset alarm threshold; when inclination exceeds the set value, it outputs a relay signal (drive current 1 A) to operate solenoid valves, buzzers or alarm lights for platform safety. It supports single- or dual-axis measurement, features temperature and linearity compensation, and includes protections against short-circuit, overvoltage and surges. All components comply with industrial application requirements.
