Dual sensor for rotary actuators,DSU35

Functional principle

Inductive sensors detect metal objects
contactless and wear-free. Dual sensors are
especially designed for position detection in
rotary actuators. They combine the reliability
of non-contact inductive sensors with the
flexibility of a modular housing system.

Operating Instructions

Intended use This device fulfills the directive 2014/34/EC and is suit-

ed for use in explosion hazardous areas according to EN
60079-0:2012 + A11 and EN 60079-11:2012.Further it is suit­ed for use in safety-related systems, including SIL2 as per IEC

61508.In order to ensure correct operation to the intended pur­pose it is required to observe the national regulations and di­rectives.

For use in explosion hazardous areas conform to classification II 2 G and II 1 D (Group II, Category 2 G, electrical equipment

for gaseous atmospheres and category 1 D, electrical equip­ment for dust atmospheres).

ated 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.

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.
