805 Series Accelerometer

805 Series Accelerometer

Description: The Model 805 is a miniature adhesive mount IEPE accelerometer built on a 3-pin TO-5 header. It is available in ±50g and ±500g dynamic ranges and offers a flat frequency response to 15kHz. The accelerometer features a hermetic construction in a TO-5 header configuration. The model 805 incorporates a stable piezo-ceramic crystal and an integrated charge converter amplifier 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.

Features:
