MAR-MX60MFA
Multi-Turn Battery-Free Absolute Encoder
Super mid-range series multi-turn battery-free 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
1. Battery free configuration achieves the same thin profile as conventional products.
The MAR-MX60MFA is the innovative absolute encoder that incorporates a proprietary Nikon battery-free design to achieve the same thin profile as conventional products. Eliminates the need for major design changes when developing new equipment or replacing existing devices or encoders.
2. High resolution
Enables up to 27-bit resolution.
Applications
- Ideal for the small AC servo motors used in compact industrial robots, service robots, mounters, and other equipment
