产品特点 FEATURES

1 General: OMRON E2A series cylindrical proximity sensor, DC 3-wire type, detects ferrous metal objects (sensing distance decreases for non-ferrous metals)

2 Electrical Specs: Power supply 12-24V DC (10-32V DC operating range), ripple ≤10% p-p; current consumption ≤10mA; output type: PNP/NPN open collector (200mA max load current, 32V DC max); residual voltage ≤2V (200mA load, 2m cable); response frequency up to1500Hz (shielded M8 models, standard target, half sensing distance setting)

3 Mechanical & Environmental: IP67 protection rating (IEC60529); operating temp -40°C to70°C, storage -40°C to85°C (no icing/condensation); vibration resistance:10-55Hz,1.5mm double amplitude for2h each X/Y/Z; shock resistance:1000m/s²,10 times each X/Y/Z; insulation resistance ≥50MΩ (500V DC between current parts and case); dielectric strength:1000V AC50/60Hz for1min

4 Protection: Power reverse polarity protection, surge suppressor, short-circuit protection (output reverse polarity protection for some models)

5 Sensing Target: Standard targets (mild steel ST37): M8→8x8x1mm, M12→12x12x1mm, M18→24x24x1mm, M30→45x45x1mm (shielded) or60x60x1mm (non-shielded)

使用场景 APPLICATIONS

1 Industrial Assembly Lines: Detect presence/absence of metal parts (e.g., screws, gears, brackets) to ensure correct assembly steps

2 Conveyor Systems: Count metal components passing by, or position items accurately for sorting/packaging

3 Packaging Machines: Detect metal packaging materials (e.g., tin cans, aluminum foil containers) to trigger sealing/cutting processes

4 Machine Tools: Monitor tool position (e.g., cutting tools in CNC machines) to prevent collisions or ensure precise machining

5 Material Handling Equipment: Detect metal pallets, bins, or containers in automated warehouses to guide forklifts/robots

6 Automotive Manufacturing: Detect metal body parts (e.g., panels, frames) during welding/painting processes for position verification

注意事项 PRECAUTIONS

1 Power Supply: Do not apply excessive voltage (over32V DC) or AC current to DC models; use insulated transformer for DC power supply (avoid auto-transformers)

2 Wiring: Correctly wire sensor and load (avoid no-load operation); keep cables away from high-tension lines (use independent metal conduit if near); cable extension ≤200m, tractive force ≤50N; M8 connector models have no output reverse polarity protection

3 Mounting: Do not hit sensor with hammer during installation; do not over-tighten nuts (use washer); maintain clearances from surrounding metal as per specs

4 Environment: Do not use in flammable/explosive gases or underwater/rain (unless protected); avoid strong acid/alkali chemical gases

5 Maintenance: Periodically check mounting (no looseness/dislocation), wiring (no loose connections/breaks), dust/metal powder accumulation, and indicator light (yellow LED); do not disassemble/modify the sensor

6 Safety: Do not use for life/property risk applications without proper system-level risk mitigation
