Structural Characteristics

1. Cylindrical uniform 36 mm outer diameter body, standardized mounting flange with 3 × M3 fixing screw holes evenly distributed at 120° intervals
2. Front housing embedded flat membrane teach keypad with dust-proof transparent protective film
3. Rear end integrated M12 4-pin circular shielded connector for power and analog signal wiring
4. Double bearing support shaft structure eliminates radial play during high-speed rotation
5. Fully sealed internal cavity with nitrogen-filled anti-condensation treatment

Working Principle

1. 24 VDC power supply energizes internal infrared LED light source to project light onto absolute optical code disc engraved with unique single-turn position coding tracks
2. Silicon photodiode array receives transmitted light signal to convert optical position code into digital binary position data
3. On-board microcontroller converts digital position value into linear 0–10 V analog voltage signal proportional to mechanical rotation angle
4. Teach keypad input modifies internal memory parameters to adjust zero offset, measuring range and output signal polarity
5. Built-in signal conditioning circuit filters analog output noise before transmitting position signal to upper controller analog input port

Advantage Highlights

1. Eliminates cost of external programming adapter; field parameter adjustment completed directly on encoder housing
2. IP65 full protection grade allows installation on equipment exposed to coolant, dust, and light splash
3. Analog voltage output compatible with all standard PLC, servo drive analog input modules without dedicated bus hardware
4. Compact size reduces overall actuator mechanical design volume compared to multi-turn bus encoders

Applicable Industries

Installation Requirements

1. Shaft radial runout during installation limited to ≤ 0.02 mm; flexible coupling mandatory, rigid direct shaft connection prohibited
2. M3 mounting screws torque controlled at 0.8 N·m; over-tightening cracks plastic housing
3. M12 connector wiring uses shielded twisted pair cable; cable shield connects to equipment metal housing single-point grounding
4. Maintain 5 mm minimum clearance around encoder housing to avoid mechanical collision during full rotation travel
5. Mounting orientation unrestricted; horizontal, vertical, inverted installation all permitted under IP65 protection

Operation & Maintenance Precautions

1. Do not apply axial impact load to encoder shaft during installation; impact damages internal optical code disc permanently
2. Ambient medium cannot contain strong corrosive chemical liquid; acid/alkaline mist environment requires additional protective cover
3. Avoid long-term direct sunlight irradiation; UV radiation degrades membrane keypad transparency and seal elasticity
4. Disconnect power supply before operating teach keypad to prevent parameter memory writing failure
5. Regular inspection of M12 connector locking ring every 6 months to prevent loose wiring causing signal drift
