Incremental Feedback Encoders for CNC/PLC: MCG-TT Linear Encoder

MCG-TT Linear Encoder

The MCG-TT linear encoder provides an ultra-low encoder profile for restricted spaces without the need to sacrifice performance or environmental robustness. Having a cylindrical shape the MCG reader-head can be fitted into a bore of only 16mm in diameter offering a wide array of application possibilities. The encoder outputs a TTL RS422 Differential Quadrature signal with a periodic reference mark.
