2-axis tilt sensor WTS3D

TTLMEMSminiature

Product overview
The WTS3D dual-axis tilt module is an in-house developed MEMS-based tilt sensor module designed for onboard attitude monitoring and industrial instrumentation. It uses an interference-resistant hardware platform with factory-calibrated MEMS sensors to minimize zero-bias, cross-axis and linearity errors. The module delivers stable operation across a wide temperature range and is supplied in tape-and-reel format for automated SMT assembly.
