Model M15 measures 0.68 in. long with 1.6 in. dia and 1.28 or 1.81 in. mounting patterns. Encoder performs in dirty environments where debris interference is high. It is available in resolutions ranging from 100–2,048 lines with 4/6/8/12 pole commutation and reference pulse options. Unit is based on MPS 160 encoder ASIC, which combines direction-sensing Hall Effect encoder and integrated index pulse with high-resolution multiplying circuit to produce quadrature output signals.
