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, low-power electronics, and a hermetically sealed LCC package. The 820M1 offers superior resolution, dynamic range, and bandwidth compared to MEMS devices, making it ideal for machine health monitoring, predictive maintenance, and impact/shock monitoring. It provides an amplified 1.25V signal output with a flat frequency response up to 10kHz.
