Functional principle

Inductive sensors detect metal objects con­tactless and wear-free. Due to the patented
multi-coil system, uprox®+ sensors have dis­tinct advantages over conventional sensors.
They excel in largest switching distances,
maximum flexibility and operational reliability
as well as efficient standardization.

Installation/Commissioning

These devices may only be installed, connected and operated by trained and qualified staff. Qualified staff must have knowledge of protection
classes, directives and regulations concerning electrical equipment designed for use in explosion hazardous areas.
Please verify that the classification and the marking on the device comply with the actual application conditions.

Installation and mounting instructions

Avoid static charging of cables and plastic devices. Please only clean the device with a damp cloth. Do not install the device in a dust flow and
avoid build-up of dust deposits on the device.
The devices must be protected against strong magnetic fields.
The pin configuration and the electrical specifications can be taken from the device marking or the technical data sheet.
In order to avoid contamination of the device, please remove possible blanking plugs of the cable glands or connectors only shortly before in­serting the cable or opening the cable socket.

Special conditions for safe operation

For devices with M12 connectors please use the supplied safety clip SC-M12/3GD.
Do not disconnect the plug-in connection or cable under voltage.
Please attach a warning label permanently in an appropriate fashion in close proximity to the plug-in connection with the following inscription:
Nicht unter Spannung trennen / Do not separate when energized.
The device must be protected against any kind of mechanical damage and degrading UV-radiation.
The IP protection rating of the connectors is given only in combination with a suitable O-ring
Load voltage and operating voltage of this equipment must be supplied from power supplies with safe isolation (IEC 30 364/UL508), to ensure
that the rated voltage of the equipment (24 VDC +20% = 28.8 VDC) is never exceeded by more than 40%.

Service/Maintenance

Repairs are not possible. The approval expires if the device is repaired or modified by a person other than the manufacturer. The most important
data from the approval are listed.
