Installation note:
Optimal performance achieved when mounted horizontally.
Use locknuts (M3, max torque 0.7N·m) for secure fixation.
Allow 2mm clearance around body for heat dissipation.
Avoid side loads exceeding 3N.
For vertical mounting, reduce payload capacity by 30%.
Cycle rate should not exceed 80% of maximum when operating above 60℃.
