产品特点 FEATURES

1 Brand: OMRON (欧姆龙), model: D2SW-01-3MS, a sealed subminiature basic switch.

2 Adopts epoxy resin sealing technology, ensuring stable sealing performance, suitable for environments exposed to water spray or excessive dust.

3 Conforms to IP67 protection rating (applicable to non-terminal models like molded lead wire versions), providing excellent dust and water resistance.

4 Rated electrical parameters: 30VDC, 0.1A (from model's 01 rating segment).

5 Contact form: SPST-NO (single-pole single-throw normally open), designed for molded lead wire models.

6 Terminal type: Molded lead wire terminals (indicated by MS in the model number).

7 Complies with international safety standards including UL, cUL, VDE, and meets RoHS directive requirements.

8 Compact size, ideal for installation in space-constrained equipment.

使用场景 APPLICATIONS

1 Automotive industry: Used in components that may encounter dust or occasional water splashes, such as door locks or window control systems.

2 Automatic vending machines: Internal switching controls for product dispensing or payment systems, resisting dust and humidity.

3 Household appliances: Refrigerators, ice-making machines, hot water heaters, air conditioners—where environmental resistance is needed for long-term reliable operation.

4 Industrial equipment: Various industrial machinery requiring stable switching under dusty or wet working conditions.

5 Bath and sanitary equipment: Controls for shower systems or bidets, withstanding water splashes.

注意事项 PRECAUTIONS

1 Do not immerse the switch in water for long periods; IP67 protection is for temporary immersion (30 minutes at 1 meter depth) and not for continuous underwater use.

2 Avoid contact with oil or chemical substances to prevent damage or deterioration of switch materials.

3 Mounting: Use M2.3 screws with plane washers or spring washers, tightening to a torque range of 0.23 to 0.26 N·m (2.3 to 2.6 kgf·cm) to ensure secure installation.

4 Operation: For pin plunger models, apply operating force directly from above; lateral force may damage the plunger or reduce sealing effectiveness.

5 Handling: Be careful when handling the switch to avoid breaking the sealing rubber, which could compromise its protective performance.

6 Micro load application: If using the switch for micro load circuits, ensure it is within the specified operating range; using ordinary load models for micro loads may lead to contact failure.
