Product Description
The TE Connectivity 820M1 is a low-cost, single-axis, board-mountable piezoelectric accelerometer designed for embedded condition monitoring and preventive maintenance applications. It features a stable piezo-ceramic crystal in shear mode with low-power electronics, sealed in a hermetic LCC package. The 820M1 offers superior resolution, dynamic range, and bandwidth compared to MEMS devices, making it ideal for machine health monitoring, predictive maintenance, embedded vibration monitoring, impact and shock monitoring, data loggers, bearing installations, and security monitoring. Its amplified 1.25V signal output and wide bandwidth up to 10,000Hz provide reliable and long-term stable output for critical monitoring tasks.
