Installation and Usage Notes
Use M2 mounting screws with plane washers or spring washers, tightening to a torque of 0.5 to 1 kgf·cm.
Apply operation forces only in the designated operating direction to prevent damage.
Solder within 3 seconds at less than 350°C to avoid degradation.
Use appropriate mounting materials, avoiding ABS or polycarbonate for mounting plates due to grease contact.
For micro load operation, ensure contact protection circuits are used to prevent contact wear.
Safety and Precautions
Consult your OMRON representative before using this product in critical systems such as nuclear, aerospace, medical, or safety-related applications. Verify equipment functions and safety margins prior to deployment.
