Silicon Designs Introduces MEMS Capacitive Sensing Modules

By DE Editors

Silicon Designs,  Inc. (SDI) has introduced the model A2260, an accelerometer designed to meet a variety of automotive R&D, crash test and vehicle dynamics testing requirements such as noise, vibration and harshness (NVH), drivetrain and powertrain testing, vehicle suspension and handling, crash event detection and airbag performance assessments.

The Silicon Designs model A2260 is tailored for zero-to-medium frequency applications, and offers integral amplification and high-drive, low impedance buffering for precision measurements. The accelerometer produces two analog voltage outputs and features a four-wire connection, supporting both single ended and differential modes. Signal outputs are fully differential about a 2.5V common mode voltage. 

Sensitivity is independent from the supply voltage of +8 to +32V. At zero acceleration, the output differential voltage is 0 VDC; at full scale acceleration, the output differential voltage is ±4 VDC. 

The sensors feature on-board voltage regulation and an internal voltage reference, which eliminates precision power supply requirements, according to the company. The sensor is relatively insensitive to temperature changes and thermal gradients. Within standard range (2 to 400 g),  most accelerometers continue to operate after sustained exposures of up to 10K g shock and with limited exposure to temperatures above +200°C.
