64C Series Accelerometer

Description: The TE Connectivity model 64C crash test accelerometer is a remarkable MEMS piezoresistive sensor specifically designed for auto safety testing in both crush zone and anthropomorphic dummy applications. The accelerometer features a full bridge output configuration with ideal gas damping tailored for outstanding shock survivability and a flat frequency response to >8kHz. The model 64C accelerometer has a standard cross-talk accuracy of <3% (with option for <1%), a standard ZMO of <±25mV and a linearity accuracy specification of <±1.0%.

The model 64C ATD dummy test accelerometer is offered in ranges from ±50 to ±6000g and has a standard operating temperature range of -40°C to +121°C. The nominal 4000Ω bridge impedance limits current draw resulting in quick warm-up time and minimal drift, unlike lower impedance designs on the market which are subject to much longer warm-up time due to gage heating effects. TE Connectivity also supplies the calibration data in a user friendly excel format which enables high volume users to quickly upload the calibration information for each sensor installed.

Users of the model 64C accelerometer are strongly recommended to also review the model 64X accelerometer which is the latest evolution of the TE Connectivity 64 series crash test sensors.
