11 Additional features: Modular construction for easy customization, yellow LED operation indicator, sensing distance 1.5-2x larger than conventional OMRON sensors to eliminate workpiece collision issues

使用场景 APPLICATIONS

1 Industrial assembly lines: Detect presence/absence of small metal parts (like screws, bolts, metal components) in assembly stations

2 Packaging machinery: Verify if metal containers or caps are properly placed before sealing/packaging

3 Conveyor systems: Count metal items passing through the line or detect jams by sensing part accumulation

4 CNC machine tools: Monitor tool position or detect if workpieces are clamped correctly on the worktable

5 Material handling equipment: Check alignment of metal pallets or components in automated storage/retrieval systems

6 Automotive manufacturing: Detect presence of metal parts (like brackets, panels) in welding or painting stations

7 Electronics production: Ensure metal PCBs or components are in the correct position on SMT lines

注意事项 PRECAUTIONS

1 Power supply: Do not apply AC voltage to this DC model; use an insulated transformer for DC power supply (avoid auto-transformers)

2 Wiring: Follow correct pin arrangement for M12 connector; do not short-circuit the load (though protected); avoid extending cable beyond 200m; keep cable away from high-tension lines (use independent metal conduit if necessary); do not apply tractive force over50N to the cable

3 Mounting: Do not strike the sensor with a hammer during installation (risk of damage/water resistance loss); tighten the M8 brass nut with torque ≤4N·m and use a washer; maintain required clearance from surrounding metal (refer to mutual interference specs for non-shielded M8 sensors); do not use underwater or expose directly to rain (cover from water-soluble machining oil for better reliability)

4 Maintenance: Periodically check for mounting position deviation/looseness, loose wiring/connections, metal powder accumulation, abnormal temperature/environment, and proper operation of the yellow LED indicator; do not disassemble or repair the sensor

5 Environment & load: Avoid using in environments with strong acid/alkaline gases; connect loads with large inrush current (like lamps, motors) via a relay to prevent sensor damage
