The Model 808M1 is a miniature adhesive
mount voltage output accelerometer built on a 3-
pin TO-8 header. It is available in ±4g and ±20g
dynamic ranges and offers a flat frequency
response to 5kHz. The accelerometer features a
hermetic construction in a TO-8 header
configuration. The model 808M1 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.
