General description of the product
Position switches and proximity switches suitable for marine use. Definitions according to IEC 60947-5-1 and IEC 60947-5-2:
• Position switch: "a pilot switch the actuating system of which is operated by a moving part of the machine, when this part reaches a predetermined position";
• Proximity switch: "a position switch which is operated without mechanical contact with the moving part";
The output of a position/proximity switch is determined by the presence or absence of a designated object. This digital output could be represented by a switched-, voltage-, current-, resistance- or frequency signal.
Typical principles of operation for sensing includes, but are not limited to:
• mechanical, capacitive, inductive, ultrasonic, photoelectric.
