产品特点 FEATURES

1 Model-specific attributes: Omron E2A-M30KS15-M1-B3 cylindrical proximity sensor, M30 metric thread size, shielded type, nominal sensing distance of 15mm ±10%, M12 4-pin connector for connection, PNP open collector output (normally open mode), brass-nickel plated body, PBT sensing surface

2 Electrical performance: Operating voltage range 10-32VDC (rated 12-24VDC with ripple ≤10% p-p), current consumption ≤10mA, maximum load current 200mA (32VDC max), residual voltage ≤2V, response frequency up to 250Hz (shielded M30 model)

3 Protection and durability: IP67 protection rating (IEC60529), operating temperature range -40°C to 70°C (storage -40°C to85°C without icing/condensation), equipped with power reverse polarity protection, surge suppressor, short-circuit protection, and output reverse polarity protection

4 Design advantages: Modular construction for easy customization; yellow LED operation indicator for real-time status monitoring; double clamping nuts for secure mounting; compatible with standard industrial installation practices

使用场景 APPLICATIONS

1 Industrial assembly lines: Detect presence/absence of metal workpieces (e.g., steel bolts, aluminum parts) to trigger sequential assembly steps

2 Conveyor belt systems: Monitor flow of metal components (like automotive engine parts, electronic chassis) to prevent jams or ensure correct spacing between items

3 Machine tool applications: Position metal workpieces on CNC mills or lathes for precise machining operations, ensuring accurate alignment before cutting

4 Packaging machinery: Identify metal packaging materials (e.g., tin cans, metal caps) to control filling, sealing, or labeling processes

5 Material handling: Detect metal pallets or containers in automated warehouses to guide robotic arms for picking, placing, or sorting tasks

6 Automotive manufacturing: Verify presence of metal body panels or fasteners during welding, painting, or final assembly stages to maintain process consistency

注意事项 PRECAUTIONS

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

2 Load management: Avoid short-circuiting the output load; for high inrush current loads (e.g., lamps, small motors), use an intermediate relay to protect the sensor

3 Wiring practices: Follow correct wiring (brown: +V, blue: 0V, black: output); keep cables away from high-tension lines—use independent metal conduit if necessary; cable extension should not exceed 200m, and tractive force on cables should not exceed 50N

4 Mounting guidelines: Do not strike the sensor with a hammer during installation; tighten M30 clamping nuts to a maximum torque of180N·m (use a washer); maintain recommended clearances from surrounding metal (e.g.,110mm side-by-side distance for shielded M30 models to avoid mutual interference)

5 Environmental considerations: Do not use in flammable/explosive atmospheres; avoid exposure to strong acid/alkali gases; do not submerge underwater (IP67 is splash-proof, not fully waterproof)

6 Maintenance and safety: Periodically check mounting tightness, wiring connections, and clean metal dust from the sensing surface; do not disassemble, repair, or modify the sensor; avoid using for life-critical applications without additional safety measures
