Wiring Diagram
Functional principle
Inductive sensors detect metal objects contactless and wear-free. For this, they use a
high-frequency electromagnetic AC field that
interacts with the target. Inductive sensors
generate this field via an RLC circuit with a
ferrite coil.

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.
This device is only suited for connection to approved Exi circuits according to EN 60079-0 and EN 60079-11. Please observe the maximum admissible electrical values.
After connection to other circuits the sensor may no longer be used in Exi installations. When interconnected to (associated) electrical equipment, it is required to perform the "Proof of intrinsic safety" (EN60079-14).
Attention! When used in safety systems, all content of the security manual must be observed.
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.
Special conditions for safe operation
avoid static charging
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.
