The model HS20 is an industrial strength hollow shaft encoder in a 2" housing that mounts directly on an existing shaft assembly.  When attached to a flexible mounting bracket or tether the encoder floats on the shaft without rotating.  IP66 sealing is available to meet the demands of most industrial environments.

STANDARD FEATURES AND OPTIONS:

  • Size 20 housing
  • Unbreakable code disk
  • Resolutions up to 720 CPR
  • Heavy duty bearings
  • IP66 sealing available
  • USAMade in the USA

Electrical:

Supply Voltages: (specify when ordering)
  — 5 ± 5% VDC
  — 5-26 VDC
  — 8-30 VDC

Current: 50 mA max (no load)
  100 mA max (line driver)

Pulse Rate: 0 - 30 kHz

Counts per Revolution: 1 to 1200 (specify when ordering)

Operating Temperature: 0° to 70° C

Output Circuit: (specify when ordering)
Single Ended:
  — 7273 open collector (30 VDC max, 50 mA max)
  — 7272 Push-Pull (50 mA max source or sink)
Differential Line Driver:
  — 7272 differential line driver (output level same as supply voltage)
  — RS422 differential line driver (with regulated 5vdc output level)

Output Waveshape:
Square wave outputs A and B are 50/50 duty cycle nominal. Output Z (index output) is approximately the width of one cycle on outputs A or B.
  — Pulse symmetry: 180°±30%
  — Pulse interval jitter: 30% max
  — Quadrature: 90°±30% max
  — Phase jitter: 30% max

Anti-jitter: (single output models only)
Increases the pulse hysteresis to ½ of a pulse width, eliminating the effects of mechanical vibration and the possible dither that results in false output pulses. For example a 10 counts per revolution output would have 18° hysteresis (i.e. 360° ÷ 10 × ½).
