The Model 834M1 is a low cost, board mountable triaxial accelerometer designed for high amplitude embedded shock applications.
Description: The Model 834M1 is a low cost, board mountable triaxial accelerometer designed for high amplitude embedded shock applications. The accelerometer features a maximum current consumption of 22 micro-amps and incorporates full power and signal conditioning. The model 834M1 is available in ±2000g to ±6000g ranges and provides a flat frequency response up to greater than 6kHz. The standard model 834 offers the same envelope with a lower maximum current consumption of 4 micro-amps.
