HR12 Optical Rotary Encoder
HR12 Spec SheetAbout HR12 Optical Rotary Encoder
Encoder Model HR12 optical rotary encoder provides an improved feedback solution in applications typically using modular encoders. The HR12 provides feedback capabilities where the others leave off – high line count resolution, high temperature operation, rugged bearing construction, large tolerance to radial and axial shaft play, commutation for brushless motor control, with a strain relieved cable. Quadrature output with index pulse and three-phase commutation provided with industrial 26C31 differential drivers. A flexible member allows for much greater tail shaft run out and TIR than can be tolerated by modular encoder designs, plus it provides 30 degrees of rotation for commutation timing.
