产品特点 FEATURES

1 Brand: OMRON (欧姆龙), model: D2HW-BR211M

2 Type: Sealed ultra-subminiature basic switch

3 Compact design: Case dimensions are 78% of conventional models, suitable for downsizing mechanical modules

4 Mounting structure: Long post on right side

5 Ratings: Supports 5VDC 1mA to 12VDC 2A

6 Actuator: Hinge lever (stainless steel material)

7 Contact form: SPDT (Single Pole Double Throw)

8 Terminals: Molded lead wires (downwards direction), standard length is 30cm (AVSS 0.5 wire; UL-approved versions use AWG24 UL1007 wire)

9 Environmental compliance: RoHS compliant, all models use lead-free materials

10 Sealing performance: IP67 (prevents ingress of dust and temporary immersion in water up to 1m for 30min)

11 Durability: Mechanical lifespan of 1,000,000 operations minimum; Electrical lifespan of 100,000 operations minimum

12 Operating range: Ambient temperature -40°C to +85°C (no icing or condensation allowed); Ambient humidity up to 95% (at 5°C to35°C)

13 Key mechanical characteristics: Extra-long stroke (hinge lever model has 1.6mm reference overtravel), reliable ON/OFF action

使用场景 APPLICATIONS

1 Industrial automation: Compact robotic arms, small conveyor belt position sensors, automated assembly line components

2 Automotive electronics: Door lock mechanisms, window regulator switches, under-dash control modules (sealed against dust and water splashes)

3 Consumer electronics: Portable wearable devices with mechanical triggers, compact kitchen appliances (e.g., small blenders, coffee makers), vacuum cleaner internal switches

4 Medical equipment: Portable diagnostic tools, compact patient monitoring devices (needs reliable sealing and small size)

5 Home appliances: Smart home sensors, small power tools, toy mechanisms (where space is limited and durability is required)

注意事项 PRECAUTIONS

1 Degree of protection: Do not use underwater (IP67 is for temporary immersion only); Avoid operating when exposed to water spray, water drops, or sudden temperature changes to prevent water intrusion

2 Mounting: Turn off power supply before mounting, wiring, or maintenance to avoid electric shock or burning; For post models (like this one), secure posts via thermal caulking or pressing into attached devices (use guides to prevent falling or rattling)

3 Handling: Do not damage the sealing rubber; Avoid applying pressure on posts in non-operating directions or uneven pressure on the actuator (may damage parts or reduce service life)

4 Wiring: For molded lead wire models, do not apply weight on wires or make sharp bends near the lead-out part (prevents switch damage or sealing deterioration)

5 Operating body: Use an operating body with low frictional resistance that does not interfere with the sealing rubber (to avoid plunger damage or sealing issues)

6 Micro load usage: If inrush or surge current occurs, insert a contact protection circuit to reduce contact wear and extend durability

7 Thermal caulking: For post models, consult OMRON sales representative for appropriate thermal caulking conditions (varies by equipment and base material)
