MAR-HX50A Straight Shaft
Multi-Turn Absolute Encoder
Nikon`s standard model M50A Series Shaft type Model
Nikon absolute encoders (rotary encoders) incorporate proprietary optical and M-sequence absolute pattern technologies to integrate high reliability and 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
High operating temperatures
Applications
- Ideal for small AC servo motors used in compact industrial robots, service robots, pick-and-place machine, and other equipment.
