Optoelectronic proximity sensor (1) Emitter fibre-optic cable (3) LED display and adjusting screw (2) Object (5) Receiver fibre-optic cable (4) Fig. 6.5.5: Diffuse sensor with fibre-optic cables (design example) Advantages of optical
proximity sensors adapted
for use with fibre-optic
cables 6.5.3 Notes on application
• Detection of objects in areas of restricted access, e.g. through holes.
• Possibility of remote installation of proximity sensor housing (e.g. hazardous
environment: heat, water, radiation, explosion risk).
• Accurate detection of small objects.
• Sensing elements can be moved. Advantages of polymer
fibre-optic cables • Mechanically stronger than fibre-glass.
• Length can be reduced easily by cutting the ends on the proximity sensor with a...
