产品特点 FEATURES

1 Slim and compact sealed limit switch with enhanced sealing performance and longer service life compared to previous D4E models.

2 Built-in flat springs with improved lever ratio ensure smooth snap action and extended operational lifespan.

3 Protection cover shields internal components from dust and oil; plunger uses a durable seal cap for long-term reliability.

4 Offers one-touch connector (simplifies wiring, reduces downtime) or screw terminal options (M3 screws with toothed washers).

5 Gold-clad contacts in minute load models are ideal for electronic control applications.

6 Available with molded terminals (including those with operating indicators like neon lamps or LEDs for easy maintenance).

7 Compliant with international standards: EN, UL, CSA, and CCC (Chinese standard; consult OMRON for certified models).

8 Consistent mounting pitch and characteristics with original D4E models for easy replacement.

使用场景 APPLICATIONS

1 Industrial automation equipment: Position detection and limit control in machine tools (e.g., OKUMA CNC machines), conveyor systems, and automated assembly lines.

2 Packaging machinery: Triggering actions based on component positions to ensure precise operation.

3 Environments with dust or oil exposure: Suitable for factories with machining processes (thanks to dust/oil protection features).

4 Electronic control systems: Minute load models are used in low-current electronic control circuits.

5 Applications requiring reliable switching: Where long service life and stable performance are critical (e.g., material handling systems).

注意事项 PRECAUTIONS

1 Avoid outdoor use or exposure to cutting oils, solvents, or chemicals; check performance under actual conditions and set maintenance/replacement cycles.

2 Protect from direct contact with cutting chips, dust, or sludge to prevent actuator/switch malfunctions.

3 Install in locations free from excessive vibration/shock to avoid contact issues, reduced durability, or false operations.

4 Do not use in environments containing silicon gas (risk of silicon oxide forming on contacts leading to interference; use surge killers if silicon products are nearby).

5 Follow tightening torque guidelines: Terminal screws (M3) 0.24–0.44 N·m; mounting screws (M4)1.18–1.37 N·m (over-tightening may damage the switch).

6 Use recommended wiring: M3 round solderless terminals with insulation tubes (0.75mm² conductor, 7mm cable diameter).

7 Ensure sufficient overtravel (OT) margin: Actual OT should be rated OT ×0.7 to 1; avoid modifying the actuator.

8 Use appropriate fuses: 10A gI/gG type (per IEC60269) in series to protect against short circuits.

9 For connector models: Insert the switch body fully into the clamp and confirm proper fitting to avoid malfunctions.
