MAR-MX60A
Multi-Turn Absolute Encoder
Super mid-range series multi-turn 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.
Features
High resolution
Enables up to 27-bit resolution.
High operating temperatures
The MAR-MX60A features a guaranteed operating temperature of 105°C. Improved resistance to various operating environment parameters increases flexibility in motor and equipment design.
Applications
- Ideal for the small AC servo motors used in compact industrial robots, service robots, mounters, and other equipment
