E6B2 Encoder


  • A wide operating voltage range of 5 to 24 VDC (open collector model).
  • Resolution of 2,000 pulses/revolution in 40-mm housing.
  • Phase Z can be adjusted with ease using the origin indicating function.
  • A large load of 29.4 N (3 kgf) in the radial direction and 19.6 N (2 kgf) in the thrust direction is permitted.
  • The load short-circuit and reversed connection protecting circuit assures highly reliable operation.
  • A line driver output model is available. (Cable extends up to 100 m.)
