2-axis tilt sensor DTS6-A1

XY4-20 mAcurrent output

Product overview
The DTS6-A1 is an industrial dynamic tilt sensor providing 4–20 mA current-loop output for reliable dynamic angle monitoring in harsh environments. It integrates a 3-axis accelerometer and 3-axis gyroscope and uses a 6-axis Kalman filter to compute dual-axis dynamic attitude in real time. The 4–20 mA output offers strong interference immunity and supports long-distance transmission up to 2000 m, making the DTS6-A1 suitable for engineering machinery and other industrial applications.
