Bulletin 845PY Digital Tachometer (5PY Mounting) Incremental Optical Encoder
Allen-Bradley's 845PY Digital Tachometer Encoder is an optical encoder that determines the angular velocity of a rotating shaft. A direct digital replacement for the standard 5PY analog tachometer, the Bulletin 845PY will mount on the same bolt-hole pattern and use the same flexible coupling. The Bulletin 845PY digital tachometer is a heavy duty, NEMA Type 4, and IP66 (IEC 529) rated optical incremental shaft encoder that is housed in a two-inch diameter enclosure. Typical applications for the 845PY include velocity feedback to a variety of DC drives and machine tools.
