Features

■Threaded barrel, M18 x 1 ■Chrome-plated brass ■Analog+ ■Extended operating range ■Temperatures up to -40 °C ■2‐wire, 14…30 VDC ■Analog output ■4…20 mA ■Cable connection ■ATEX category II 1 G, Ex-zone 0 ■ATEX category II 2 D, Ex-zone 21 Wiring diagram Functional principle Inductive TURCK sensors with analog output accomplish simple control tasks. They provide a current, voltage or frequency signal proportional to the target's distance. The output signal is linear to the distance of the target over the entire sensing range.

For use in explosion hazardous areas conform to classification II 1 G and II 2 D (Group II, Category 1 G, electrical equipment for gas-atmospheres and category 2 D, electrical equipment for dust atmospheres) Marking (see device or technical data sheet) É II 1 G Ex ia IIC T6 Ga und É II 2 D Ex ia IIIC T85°C Db acc. to EN 60079-0, -11 Local admissible ambient temperature -25…+65 °C 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). 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. 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.
