产品特点 FEATURES

1 Brand: OMRON, Model: D2HW-C211H sealed ultra-subminiature basic switch

2 Ultra-compact design: Case dimensions are 78% of conventional models, contributing to downsizing of mechanical modules

3 High sealing performance: IEC IP67 protection (suitable for dust-tight and temporary water immersion scenarios)

4 Hinge lever actuator: Operating force max 0.75N (76 gf), releasing force min 0.07N (7 gf), overtravel reference value 1.6 mm, movement differential max 0.5 mm for reliable ON/OFF action

5 Environmentally friendly: All models are lead-free and RoHS compliant

6 Durable: Mechanical durability of at least 1,000,000 operations; electrical durability of at least 100,000 operations

7 Wide operating temperature range: -40°C to +85°C (no icing or condensation)

8 M3 screw mounting: Secure installation with specified torque of 0.27-0.29 N·m

使用场景 APPLICATIONS

1 Industrial automation: Position detection in conveyor belts, trigger controls in packaging machines

2 Consumer electronics: Door/lid sensors in washing machines, dryers, and microwave ovens

3 Office equipment: Paper jam detection in printers, document feed triggers in scanners

4 Medical devices: Flow control in infusion pumps, component actuation in diagnostic instruments

5 Automotive accessories: Seat adjustment position sensors, car alarm trigger components

注意事项 PRECAUTIONS

1 Do not use underwater (IP67 is for temporary immersion only); avoid exposure to water spray, water drops, or sudden temperature changes

2 Soldering guidelines: For solder terminals, use iron tip ≤300°C for ≤3 seconds; no force applied for 1 minute post-soldering

3 Mounting: Turn off power before installation/wiring; M3 screws tightened to 0.27-0.29 N·m (over-torque may damage sealing)

4 Operation: Use low-friction operating body that doesn't interfere with sealing rubber; avoid uneven pressure on actuator/posts

5 Wiring (molded lead variants): No weight on wires; no sharp bends near wire exit

6 Handling: Do not damage sealing rubber; avoid pressure on posts in non-operating directions

7 Micro load usage: Install contact protection circuit if inrush/surge current exists to reduce contact wear
