MODEL 805M1 ACCELEROMETERSPECIFICATIONSTO-5 Series Accelerometer
3-Wire Voltage Output
Low-Cost, Embedded Applications<0.80mA Power Consumption

The Model 805M1 is a miniature adhesive
mount voltage output accelerometer built on a 3-pin TO5 header. It is available in ±20g to ±500g dynamic
ranges and offers a flat frequency response to 12kHz.
The accelerometer features a hermetic construction in a
TO-5 header configuration. The model 805M1
incorporates a stable piezo-ceramic crystal with lowpower electronics in a 100% shielded housing suitablefor many embedded OEM applications.
The model 805M1 accelerometer is offered intwo configurations; one for adhesive mounting and onefor stud mounting. An isolating cover option is also
included for the standard model.
