Koyo encoders. TRD-NA Series.

d50 Absolute Type

 Ultracompact design with an outside diameter of φ50 mm / depth of 35 mm
  1. Thoroughly strengthened dustproof and waterjet-proof type with robust aluminum die-cast cover
  2. High axial load due to the strengthened spindle of φ8 mm stainless steel shaft.
  3. Gray code output that eliminates reading errors
  4. Use of a metal slit board delivers an impact resistance of 980 m/s2.
(2,048 pulses for glass slit board)
