ACEINNA MTLT335D Dynamic Tilt Sensor with CAN Output

ACEINNA MTLT335D Triple-Redundant 1.3°/h Dynamic Tilt Sensor with CAN Output is an easy-to-use 6-DOF IMU packaged in a rugged sealed over-molded plastic or aluminum housing. The MTLT335 includes triple-redundant 3-axis MEMS accelerometers and rate gyros fully calibrated over the -40°C to +85°C operating temperature range. A 168MHz ARM M4 CPU provides processing power with a Floating Point Unit. An internal Kalman Filter provides gyro-compensated and corrected pitch and roll outputs. The ACEINNA MTLT335 is designed for use in 12V and 24V vehicle platforms.

The sealed packaging meets the challenging performance, reliability, and cost requirements of the automotive, construction, and agriculture vehicle markets. This dynamic tilt sensor has been developed per the ISO13849 Machine Safety standard and fulfills category 2 as specified in DIN EN ISO 13849-1:2016. The MTLT335D can also be used in safety functions up to Performance Level d as specified in DIN EN ISO 13849-1:2016.
