2.1 Improper use
THE BUMPER AND THE CONTROL UNIT SHALL NOT BE USED:

In control circuits and equipment featuring inadequate stop time or inadequate control
instruments/mechanisms.

In environments which can adversely affect the correct working of the bumper and/or of the control unit
(i.e.: environments with the presence of chemical, corrosive agents).

To start the machine movement.

In environments where there is a risk of explosion or a risk of flood (where devices risk to be covered
with water).

In places where there is the passage of heavy means (forklift trucks, motor vehicles and similar ones).

Beyond the use and storage temperature limits.

In applications where finger detection is required.
2.2 Environmental limits
The material of the sensor can resist the deteriorative effects of ozone, sun rays, water, acids, bases, oily
liquids, fats. Hydraulic oils and cutting oils do not cause any damage.
Very aggressive liquids such as phosphoric acid, nitric acid, Freon, etc… can cause the deformation and the
loss of the material characteristics. The exposure to very high temperatures damages the product (the
product should be stocked at a temperature in the range -10 and +50°C).
