MOUNTING AND CONNECTING 1. 2. 3. 4. 5. 6. 7. Dissipation - 1 W Weight - 50 gram (approx.) Volume - 0.07 litre Housing material - plastic Cover material - aluminum alloy Tolerances - H12; h12, T12

Ù - sensing axis, 90°± 1° to the reference plane

1. Do not deform housing and output pins 2. Fragile components inside - no shocks, no drop 3. Treat as electrostatic sensitive unit 4. Power must be off during connecting 5. After installation calibrate bias and scale factor 6. Soldering to contacts by low-temperature solder 7. Do not shield top cover from air flow to avoid overheating.
