This is a smaller version (2.5" diameter) of the HS35 standard industrial Hollow Shaft style encoder. It is a rugged encoder designed to mount directly to a shaft. Installed length is about 2" and it uses a tether to prevent the encoder body from rotating.

* Cast metal housing * Dual preloaded bearings * O-Ring sealed for IP65 rating * Corrosion resistant shaft *

Standard Features Include

  • Rotating shaft seal (SS in the model number)
  • Two channels in quadrature plus an index and complements (ABZC)
  • Multi-voltage line driver ( 5 -28 VDC in, V out = V in)
  • Cable termination, 18” long, with gland seal at encoder body

Your Choice of:

  • Tethers: R1= Block and pin, for large axial play; R2= Tether arm universal mount
  • Resolutions from 250 to 2048 cycles per turn
  • Mounting shaft diameters: 75 = 0.750", 62 = 0.625", 50 = 0.50", 37 = 0.375"
