Application Design and operating principle
The magnetic safety sensors of the RC Si series are suitable formonitoring the position of sliding,hinged and removable protectivedoors.They can only be used for safety duties to DIN VDE 0660-209in combination with a safety guard monitor for protection up to Con-
trol Category 4 to EN 954-1.The use of magnetic safety sensors is of particular advantage incases where extremely dirty conditions can occur or high hygienicstandards need to be maintained.This is provided by the simplicity of
cleaning the units.A further advantage is the facility for concealed
mounting behind non-magnetic materials.Working surfaces and storage areas can be arranged withouttheneed for dust-collecting edges or other functionally required cutoutsor projections.The magnetic safety sensors of the RC Si series can
also be applied in cases where a precise approach is notpossible and
greater tolerances are required. These devices comprise a multi-channel magnetic safety sensorand an actuating magnet.The magnetic safety sensors are actuatedby a coded magnetwithoutany mechanical contact.The devices canbe selected with one NC and one NO contactor with two NC contacts.
All described magnetic safety sensors are supplied with a pre-wired
cable.The magnetic safety sensors of the RC Si series are protected toprotection class IP 67.The mounting site of magnetic safety sensors mustbe free ofmagnetic fields.All magnetic safety sensors described in this chapter bear the CEmark according to the Machinery Directive 98/37/EC. 1717 ApplicationOn hinged doorsOn sliding doors
