Model 805M1 Accelerometer
TO-5 Series Accelerometer
3-Wire Voltage Output
Low-Cost, Embedded Applications
<0.10mA Power Consumption
The Model 805M1
is a miniature adhesive
mount voltage output accelerometer built on a 3-
pin TO-5 header. It is available in ±20g and
±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 low power
electronics in a 100% shielded housing suitable
for many embedded OEM applications.
The accelerometer is offered in two
configurations; one for adhesive mounting and
one for stud mounting.
