| Principle of operation |
| |
| The optoelectronic sensors in the switch operate using
modulated infrared light. Visible light therefore cannot affect their
operation. Infrared light can penetrate even severe dirt on the optics,
and thus ensures reliable operation. Proximity switch transmitters and
receivers are matched to one another. The sensor receiver has an
integral bandpass filter to amplify primarily the transmitted frequency.
All other frequencies are attenuated. This gives the units good
resistance to extraneous light. Precision plastic optics ensure long
range and long sensing distances. There are two types of optical
proximity switch, distinguished by their function. |
