- 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
- 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
- Installation and Usage Notes
- 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
- 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
