The SPO-TT glass linear encoder (glass scale) is intended to be a direct replacement for the Heidenhain LS177 Encoder. The SPO Series of photoelectric linear encoders features reproducible thermal behavior and has a reversible reading head with detachable cable. The encoder provides a TTL A Quad B output in either 3 or 5 micron accuracy grade and 0.1 or 0.2 micron resolution. Distance coded reference marks are optional. Travel lengths up to 3240mm (127.5") available.
Note: When requesting a quote please specify the travel length, accuracy grade, cable length, and connector type. When ordering please specify the required output resolution, the measuring length, reference mark type, accuracy, cable length, connector type, and mounting spar. See downloadable data sheet for more information.
The Newall Advantage
- Replace your Heidenhain LS177 Encoder for a fraction of the cost
- Improved availability compared to Heidenhain
Quick and Easy Installation
