The ACEINNA MTLT335 is an easy-to-use high-performance 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, which are fully calibrated over the full operating temperature range. The processing power is provided by a 168MHz ARM M4 CPU with a Floating Point Unit. An internal Kalman Filter provides gyro-compensated and corrected pitch and roll outputs.

The MTLT335D triple redundant sensor array and proprietary fault detection logic seamlessly excludes a failing sensor and continues normal operation increasing machine reliability and up time. The MTLT335 has been developed in accordance with the ISO13849 Machine Safety standard, and fulfills the requirements of category 2. It can be used in safety functions up to Performance Level d as specified in DIN EN ISO 13849-1:2016.
