产品特点 FEATURES

1 Series: OMRON E2A cylindrical proximity sensor (model: E2A-M12LS04-M1-B3)

2 Sensing performance: Shielded type with 4mm sensing distance (1.5-2 times that of conventional OMRON sensors), response frequency up to 1000Hz for fast detection

3 Construction: Brass nickel-plated housing (long barrel, M12 thread size), PBT sensing surface, M12 4-pin connector for convenient connection

4 Electrical specs: DC 3-wire PNP open collector output, rated voltage 12-24VDC (operating range:10-32VDC), max load current 200mA, residual voltage ≤2V

5 Protection: IP67 waterproof/dustproof rating, built-in reverse polarity protection, surge suppressor, and short-circuit protection

6 Environmental adaptability: Operating temperature -40°C to70°C (storage: -40°C to85°C), resistant to vibration (10-55Hz,1.5mm double amplitude) and shock (1000m/s²,10 times per axis)

7 Additional features: Yellow LED operation indicator for visual status monitoring, modular design for customization, compatible with standard industrial mounting (clamping nuts included)

使用场景 APPLICATIONS

1 Assembly lines: Detect presence/position of small metal workpieces (e.g., screws, nuts) to trigger sequential assembly steps

2 Conveyor systems: Monitor flow of metal components (e.g., automotive parts, electronic modules) to prevent jams or ensure proper spacing

3 Machine tools: Position workpieces on CNC machines/lathes for precise machining operations

4 Packaging equipment: Identify metal packaging materials (e.g., tin cans, aluminum containers) to control filling/sealing processes

5 Robotics: Enable robots to detect metal objects (e.g., tools, parts) for accurate pick-and-place tasks

6 Material handling: Detect metal pallets/bins in warehouse automation systems to optimize storage/retrieval workflows

注意事项 PRECAUTIONS

1 Power supply: Do not apply AC voltage to DC models; ensure input voltage stays within the 10-32VDC range

2 Wiring: Follow correct pin arrangement for M12 connector; avoid load short-circuits. Keep cables away from high-tension lines (use metal conduit if needed). Do not extend cables beyond 200m

3 Mounting: Do not strike with a hammer during installation (risk of damage/waterproof failure). Tighten M12 nuts to 30N·m with a washer. Maintain required clearance from surrounding metal (refer to mutual interference data)

4 Environment: Do not use underwater or in strong acidic/alkaline gas environments. Avoid temps outside operating/storage ranges

5 Load handling: For high inrush current loads (e.g., lamps, motors), connect via a relay to protect the sensor

6 Maintenance: Periodically check for loose mounting/wiring, dust accumulation on sensing surface, and LED indicator operation. Do not disassemble the sensor
