Wiring Diagram
Functional principle
Inductive sensors detect metal objects contactless and wear-free. uprox® Factor 1 sensors have significant advantages due to their
patented ferrite-coreless multicoil system.
They detect all metals at the same large
switching distance and are resistant to magnetic fields.

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.
If the devices and the cable could be subject to mechanical damage, they must be protected accordingly. They must also be shielded against
strong electro-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.
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.
