Koyo encoders. TRD-NA Series.
d50 Absolute Type
Ultracompact design with an outside diameter of φ50 mm / depth of 35 mm- Thoroughly strengthened dustproof and waterjet-proof type with robust aluminum die-cast cover
- High axial load due to the strengthened spindle of φ8 mm stainless steel shaft.
- Gray code output that eliminates reading errors
- Use of a metal slit board delivers an impact resistance of 980 m/s2.
