Intended use
The inductive proximity switch is for use as contactless wearout-free limit switch in
industrial control systems.
The inductive proximity switch may only be connected to electronic evaluation devices that
have a valid EC type examination certificate for hazardous areas with potentially explosive
gas and dust atmosphere and do not exceed the electrical limits of the inductive proximity
switch. It can be mounted inside gas-hazardous areas that require equipment of category 1G
(zone 0) or dust-hazardous areas that require equipment of category 1D (zone 20).
If there are additional regulations for the particular design regarding the installation, they must be observed as well.
