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