产品特点 FEATURES

1 Model: E2A-M18LS08-M1-C3 (cylindrical shielded proximity sensor, M18 size, long barrel)

2 Sensing performance: Shielded type with 8mm ±10% sensing distance (for ferrous metal; sensing distance reduces for non-ferrous metals like aluminum, brass), standard target size 24×24×1mm mild steel ST37

3 Connection: M12 4-pole connector for quick and reliable connection, facilitating on-site maintenance and replacement

4 Output configuration: DC 3-wire NPN open collector output, maximum load current 200mA (100mA max under ambient temp -40°C to -25°C and power voltage30-32VDC), residual voltage ≤2V

5 Durability: IP67 protection rating (dust-tight and water-resistant per IEC60529), operating temperature range -40°C to70°C (storage -40°C to85°C), vibration resistance (10-55Hz,1.5mm double amplitude for 2 hours each in X/Y/Z directions), shock resistance (1000m/s²,10 times each in X/Y/Z directions)

6 Protection functions: Integrated output reverse polarity protection, power source reverse polarity protection, surge suppressor and short-circuit protection to prevent damage from electrical anomalies

7 Response frequency:500Hz, capable of high-speed detection for dynamic metal object sensing in automated production lines

8 Material: Case made of brass-nickel plated, sensing surface PBT, clamping nut brass-nickel plated for corrosion resistance and mechanical strength

使用场景 APPLICATIONS

1 Industrial conveyor systems: Detect presence/absence of metal workpieces (e.g., automotive components, metal parts) on conveyors to trigger sorting, counting or stop/start operations

2 Machine tool automation: Positioning metal workpieces in CNC machines, lathes or milling machines to initiate machining processes once the part is correctly aligned

3 Packaging industry: Detecting metal containers (e.g., tin cans, aluminum cans) on packaging lines to control filling volume, sealing or labeling steps

4 Assembly line verification: Checking if metal fasteners (screws, bolts, nuts) are properly installed in electronic devices, appliances or mechanical equipment

5 Storage material handling: Identifying metal pallets, bins or racks in AGV (Automated Guided Vehicle) systems or robotic arm operations to guide movement and pick-and-place tasks

6 Printing and paper processing: Detecting metal rollers or gears in printing machines to ensure proper synchronization of production steps

注意事项 PRECAUTIONS

1 Power supply: Do not apply voltage exceeding the rated range (12-24VDC, ripple p-p ≤10%); never connect AC power to DC models to avoid damage

2 Load management: Avoid short-circuiting the output load; ensure the load current does not exceed the specified limit (200mA max,100mA max under extreme temp/voltage conditions)

3 Wiring guidelines: Use insulated transformers for DC power supply (avoid auto-transformers); keep sensor cables away from high-tension lines (use independent metal conduit if nearby); do not extend cables beyond200m, and limit tractive force on cables to ≤50N

4 Mounting instructions: Do not strike the sensor with a hammer during installation; tighten the clamping nut with the correct torque (70N·m for M18 size) and use a washer to prevent damage; maintain required clearance from surrounding metal (refer to mutual interference specs: for M18 shielded models, side-by-side installation distance ≥60mm, face-to-face distance ≥35mm)

5 Environmental restrictions: Do not use underwater or expose to prolonged rain (despite IP67 rating); avoid flammable/explosive gases and strong chemical gases (e.g., nitric acid, chromic acid) to prevent corrosion or malfunction

6 Maintenance: Periodically inspect mounting stability (no looseness/dislocation), wiring integrity (no loose connections/breaks), sensor surface (clean metal powder/dust), and indicator light operation; never disassemble or modify the sensor
