- **Actuating Stroke**: 5mm, over-travel 2mm, total stroke 7mm  

- **Protection Level**: IP62 (dust-proof and splash-proof)  

- **Operating Temperature**: -5°C ~ +40°C  

- **Installation Category**: Category II  

- **Pollution Degree**: Level 3  

3. Certifications and Standards  

- **Domestic Certification**: China CCC Certification  

- **International Standards**: Compliant with GB/T 14048.5 and IEC 60947-5-1  

4. Physical Characteristics  

- **Housing Material**: Aluminum alloy  

- **Operating Head Material**: Silver contacts  

- **Weight**: Approximately 200g (estimated based on similar series products)  

- **Overall Dimensions**: Approximately 73mm×40mm×28.5mm (length×width×height, reference drawings of similar series products)  

- **Mounting Hole Size**: 2×φ12mm, spacing 50mm  

5. Environmental Adaptability  

- **Altitude**: ≤2000 meters  

- **Humidity Conditions**: Relative humidity ≤50% at maximum temperature +40°C; higher humidity allowed at lower temperatures (e.g., humidity ≤90% at 20°C)  

- **Vibration Requirements**: Installation location should be free from significant vibration  

 6. Precautions  

- **Over-travel Limitation**: Total stroke shall not exceed 7mm to avoid internal structure damage  

- **Operation Speed**: Extremely slow or fast operation may cause contact instability or mechanism damage; use at rated frequency is recommended  

- **Load Limitation**: Not recommended for micro-loads (e.g., voltage ≤100V), which may reduce contact reliability  

 2. Application Scenarios  

This switch is mainly used for **stroke control of moving mechanisms**, such as:  

- Limit protection for machine tools and elevators  

- Position detection in motor control circuits  

- Program control in automated production lines  

3. Installation and Usage Notes  

1. **Installation Requirements**  

   - Must be installed vertically to avoid internal structure damage caused by excessive over-travel (total stroke ≤7mm)  

   - Refer to the product manual for fixing hole dimensions; use of standard wires for connection is recommended  

2. **Environmental Conditions**  

   - Avoid use in flammable, explosive, or corrosive environments  

   - Installation location should be free from significant vibration and at an altitude not exceeding 2000 meters  

4. Purchase and Market Information  

**International Market**  

   - Current search results do not clarify whether this model has passed UL certification or is sold in the U.S. market  

   - Chint Power has photovoltaic projects in the U.S., but local supply information for travel switches needs further confirmation
