MODEL 805M1 ACCELEROMETER SPECIFICATIONS 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 TO- 5 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 low power electronics in a 100% shielded housing suitable for many embedded OEM applications. The model 805M1 accelerometer is offered in two configurations one for adhesive mounting and one for stud mounting. An isolating cover option is also included for the standard model.
