Warning
1. Confirm the specifications.
Products represented in this catalog are designed only for use in compressed air systems (including
vacuum).Do not operate at pressures, temperatures, etc., beyond the range of specifications, as this can
cause damage or malfunction.(Refer to the specifications.)Please contact SMC when using a fluid other
than compressed air (including vacuum).We do not guarantee against any damages if the product is used
outside of the specification range.
2. Take safety measures (e.g. mounting protective covers) when there is a danger of fingers being
caught between the magnet gripper and the workpiece or with moving workpieces causing personal
injury.
3. Select a model whose holding force is compatible with the workpiece mass.
Expected holding force may not be obtained depending on the material or shape of the workpiece, please
evaluate the safety against the fall of workpiece with actual machine.
4. Do not use in applications where excessive external force or impact force may be applied to the
gripper.
5. Consider the possibility of a power source related malfunction.
Measures should be taken to prevent injury and equipment damage in the event that there is a power
malfunction to equipment controlled by air pressure, electricity or hydraulics,etc.
6. Consider the action of the product in the event of an emergency stop.
Devise a safe system so that if a person engages the emergency stop or if a safety device is tripped during
a system malfunction,such as a power outage, the operation of the magnet gripper will not cause a hazard
to humans or damage the equipment.
7. Consider the action when operation is restarted after an emergency or abnormal stop.
Design machinery so that bodily injury or equipment damage will not occur upon the restart of operation.
8. Do not disassemble the product or make any modifications, including additional machining.
Doing so may cause human injury and/or an accident.
9. Refer to the Auto Switches Precautions (Web Catalog) if using with an auto switch.
10. Risk to people with pacemakers
The product has a magnet inside. It may interfere with the use of an electronic equipment such as a
pacemaker. People with pacemakers should stay away from the magnet gripper or take safety measures to
block the magnetic force.
