产品特点 FEATURES

1 Brand and model: OMRON E2A-S08KN04-M5-B2 cylindrical proximity sensor

2 Structural parameters: M8 thread size, non-shielded type, stainless steel body, PBT sensing surface, M8 3-pin connector (M5 type)

3 Sensing performance: Sensing distance of 4mm ±10% (for ferrous metal ST37, standard target size 8×8×1mm), response frequency up to 1000 Hz, normally closed (NC) operation mode, PNP open collector output

4 Electrical specs: Operating voltage range of 10-32 VDC (rated 12-24 VDC, ripple ≤10% p-p), max current consumption of 10mA, max load current of 200mA (32 VDC max), residual voltage ≤2V (200mA load, 2m cable)

5 Environmental resistance: IP67 protection grade, operating temperature range of -40°C to 70°C (no icing/condensation), storage temperature range of -40°C to 85°C; vibration resistance (10-55Hz,1.5mm double amplitude for 2h each X/Y/Z), shock resistance (1000m/s²,10 times each X/Y/Z)

6 Additional features: Equipped with yellow LED operation indicator; integrated protection circuits (power reverse polarity, surge suppression, short-circuit protection); modular construction for easy customization; larger sensing distance (1.5-2x conventional OMRON sensors) to avoid workpiece collision issues

使用场景 APPLICATIONS

1 Industrial assembly lines: Detect presence/absence of small ferrous metal parts (e.g., screws, nuts, clips) during product assembly processes

2 Packaging machinery: Position metal packaging components (e.g., metal cans, foil seals) to ensure accurate packaging operations

3 Conveyor systems: Sensing small metal workpieces on conveyor belts for material flow control and sorting

4 Automotive component manufacturing: Detect metal brackets, pins, or fasteners in automated assembly stations

5 Electronic device production: Identify metal parts in PCB assembly lines (e.g., metal connectors, shielding cases) to ensure correct placement

6 Robotic handling systems: Assist robotic arms in locating metal workpieces for precise pick-and-place operations

7 Machine tool applications: Detect tool presence or workpiece position in milling/drilling machines to prevent machining errors

注意事项 PRECAUTIONS

1 Power supply: Do not apply AC voltage to DC models; avoid exceeding the rated voltage range (10-32 VDC) to prevent sensor damage

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

3 Mounting guidelines: Do not strike the sensor with a hammer during installation; do not over-tighten the clamping nut (use a washer); maintain specified clearance from surrounding metal (for non-shielded M8 short barrel, keep 80mm distance between sensors when installed face-to-face,60mm when side-by-side)

4 Environmental usage: Do not use the sensor underwater, in rain, or in environments with strong acid/alkali gases; operate within the specified temperature (-40°C to70°C) and humidity (35%-95%) ranges

5 Wiring notes: Keep sensor cables away from high-tension lines; if necessary, use independent metal conduit for wiring to avoid interference

6 Maintenance and inspection: Periodically check for loose mounting, damaged wiring connections, accumulation of metal dust on the sensing surface; verify the yellow LED indicator works normally; do not disassemble or modify the sensor
