MODEL 40A ACCELEROMETERSPECIFICATIONSDIMENSIONS±25g to ±2000g Dynamic Range
Fluid Damped, DC Response
Compliant to SAE J2570
Temperature Compensated

The Model 40A Accelerometer is a small
piezoresistive accelerometer designed to be compliant
with the latest SAE J211/J2570 (AUG2009)
specifications. This unit features built-in mechanicalstops, anodized aluminum alloy housing and flexible
cable output. The sensing element is fluid damped toextend useful frequency range and reduce the adverse
effect of high frequencies ringing caused by sensorresonance

FEATURES
