Product Introduction


The SWR14X/SWR14D is a digital tilt switch specifically developed for safety-critical leveling and platform-stabilization applications. It features an integrated relay output, offering flexible and convenient operation. Users can define custom alarm thresholds; when the tilt angle exceeds the preset safety limit, the device triggers a passive relay contact (with a 1A drive current). This can directly actuate solenoid valves to control hydraulic leveling jacks, making it an ideal solution for equipment such as construction vehicles and aerial work platforms.


The device undergoes dual-stage compensation for temperature characteristics and linearity, ensuring superior measurement accuracy. It is equipped with comprehensive protection circuitry—safeguarding against short circuits, high-voltage transients, reverse polarity, and surge impacts—to effectively resist various electrical disturbances encountered in the field. Built with industrial-grade components, including a high-performance MCU, a ruggedized (conformal-coated) PCB, premium imported cabling, and a durable metal housing designed for a wide temperature range, the unit is engineered for long-term, reliable operation in harsh industrial environments characterized by high humidity, vibration, and significant temperature fluctuations.

Resolution: Refers to the smallest change in the measured quantity that a sensor can detect and distinguish within its measurement range.

Measurement Accuracy: Refers to the combined error of a sensor—under room temperature conditions—encompassing linearity, repeatability, hysteresis, zero-point deviation, and cross-axis error.

Long-term Stability: Refers to the deviation between the maximum and minimum output values of a sensor after one year of continuous operation under room temperature conditions.

Response Time: Refers to the time required for a sensor’s output to reach a specified value following a change in the measured angle.
