Functional engineering application
The BLX-ENC-3500 Optical Incremental Rotary Encoder delivers precision shaft angle, position, and rotational speed feedback for CNC machinery, packaging lines, printing presses, textile looms, and automated conveyors across Kenya. Constructed with a heavy-duty 50mm aluminum housing, clamping flange, and precision dual ball bearings, the encoder handles high radial and axial shaft loads up to 6000 RPM. The optical disc employs chrome-on-glass photolithography, providing high signal contrast and immunity to magnetic interference. Providing complementary quadrature output signals (A, B, and index Z) compatible with both Push-Pull (HTL 5-24V) and RS-422 Differential Line Driver (TTL) interfaces, the encoder connects directly to PLCs, high-speed counters, and digital batch indicators.
Heavy-duty 50mm optical incremental rotary encoder with 1024 PPR resolution, solid 8mm stainless shaft, clamping flange, A/B/Z quadrature outputs, 5-24VDC supply, and IP65 aluminum housing.

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.
