Function & Performance Features

• Heavy-duty hollow blind shaft design directly mount on motor drive shaft without separate coupling, reduce mechanical installation space
• HTL-P high-power differential output ensures stable signal transmission up to 350m cable length, anti-EMI interference for long-distance machine tool wiring
• Bi-directional rotation detection via A/B quadrature phase sequence, identify clockwise/counter-clockwise rotation direction for reversible motion systems
• Z index zero pulse provides accurate absolute position reference once per revolution for homing & origin calibration
• Ultra-wide -40°C to +100°C operating temperature suitable for furnace, steel mill, outdoor heavy machinery
• IP66 fully sealed housing withstands cooling water spray, metal dust, lubrication oil mist environment
• High mechanical load bearing shaft tolerates heavy radial/axial impact load from large drive motors
• Salt mist corrosion resistant design per ISO 12944 C5-M marine industrial corrosion standard
• Built-in reverse polarity power supply protection circuit prevents wiring error damage

Working Principle

Material & Structural Characteristics

• Main Housing: Die-cast aluminum alloy with anti-corrosion passivation coating, high mechanical impact resistance
• Rotor Hollow Shaft: Solid stainless steel precision machined blind bore shaft, wear-resistant for long-term rotation
• Sealing System: Double-layer fluorine rubber shaft lip seal + O-ring housing sealing for IP66 water/dust protection
• Internal Optical Assembly: Glass precision grating disc, shock-absorbing silicone buffer mount to isolate vibration transfer
• Terminal Connection: Dual side-mounted sealed terminal box, stainless steel cable gland anti-loosening cable fixation

Installation Requirements

1. Blind hollow shaft directly sleeved onto motor drive shaft, secure via radial set screw with specified torque 3–4 N·m to avoid shaft slip
2. Allow maximum concentricity tolerance ≤0.1mm between encoder hollow bore and drive shaft to prevent internal bearing premature wear
3. Cable gland installation must tighten rubber sealing ring to maintain IP66 enclosure rating; use shielded twisted-pair differential signal cable
4. Mount encoder flange with 4 standard M6 mounting bolts evenly torqued to distribute mechanical stress
5. Avoid mounting position exposed to continuous high-temperature radiant heat source; maintain ≥20cm distance from furnace exhaust
6. Signal cable shield single-point grounding at PLC/controller receiving terminal end only, double grounding causes ground loop signal distortion

Typical Application Scenarios

• Steel rolling mill main drive motor rotational speed & position measurement
• Port crane, container gantry crane lifting mechanism speed feedback
• Heavy-duty mining conveyor belt drive motor overspeed monitoring
• Wind turbine generator main shaft rotational position detection
• Hydraulic press main drive motor closed-loop speed control
• Outdoor construction machinery, asphalt paving machine motion feedback
• Furnace heat treatment equipment high-temperature motor position sensing

Operation & Maintenance Precautions

1. Do not disassemble sealed housing; internal optical components contamination voids warranty and measurement accuracy
2. Tighten shaft set screw quarterly to prevent shaft slippage leading to lost position feedback
3. Clean terminal box cable gland area monthly to remove accumulated metal dust and cooling water residue
4. If output signal pulse loss occurs, first inspect shield cable damage and grounding connection before encoder replacement
5. Avoid excessive radial hammer impact on hollow shaft during installation to deform internal precision bearing
6. Storage environment must maintain dry, non-corrosive gas, temperature range -20°C ~ +70°C
7. Encoder must stop rotating before disconnection of signal cable to prevent electrostatic discharge damage to internal amplifier circuit
