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
4. 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
