MAR-HX60MFA ⌀79 Oldham coupling

Multi-Turn Battery-Free Absolute Encoder

Super mid-range series multi-turn Oldham coupling model to suit a wide range of applications

Nikon absolute encoders (rotary encoders) incorporate proprietary optical and M-sequence absolute pattern technologies to combine high reliability with compact dimensions. Used in a broad range of industrial machinery, including industrial robots for automotive production lines and machine tools, they have won widespread acclaim as standard sensors capable of detecting the rotational displacement of robot arms and other equipment as absolute values.
