Common questions on this part
The encoder outputs two pulse trains (A and B) shifted by 90 electrical degrees. When rotating clockwise, Channel A leads Channel B; when rotating counter-clockwise, Channel B leads Channel A. High-speed PLC counter modules detect this phase shift to track direction automatically.
Yes. The 24V Push-Pull (HTL) output connects directly to 24VDC high-speed counter inputs (HSC) on Siemens S7-1200, Delta DVP, Omron CP1E, and Schneider M221 PLCs without signal conditioning.
A flexible helical beam coupling or Oldham coupling (Ø8mm to motor shaft diameter) must always be used to absorb slight mechanical shaft misalignments and protect internal bearings.
The Z (Zero Index) channel produces exactly one high pulse per complete 360° mechanical revolution, commonly used as a precise homing reference mark for machine axes.
Yes. 1024 PPR and 2500 PPR encoders and matching flexible shaft couplings are stocked at STARNEX in Nairobi.
