MAR-MCX63A
Hollow-Shaft Multi-Turn Absolute Encoder
Large inner diameter hollow-shaft absolute encoder: Successor to the MC43A
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. High resolution
Provides up to 24-bit resolution.
2. High operating temperatures
The MAR-MCX63A features a guaranteed operating temperature of 105°C.
Improved resistance to various environment parameters increases flexibility in motor and equipment design.
Applications
- Ideal for hollow-shaft actuators used in multi-joint robots
- The lineup now includes a large inner diameter hollow-shaft encoder (inner diameter: ⌀63 mm, outer diameter: ⌀113 mm, thickness: approx. 12 mm).
