FESTO Безконтактен пневматичен датчик RFL-4

Reflex Sensors

Type RFL-4 & RFL-15

The reflex sensor is used as a non-contact signaling device. It is capable of sensing indicating instruments, monitoring press and stamping dies (sheet gauge, perforations, layering), including edge-guiding and magazine control, metering and measuring. Depending on the type used, a range covering 0.004 to 0.008 in / 0.1 to 0.2 mm can be detected.

High pollution, noise interference, explosive atmosphere, total darkness or the transparency or magnetism of objects do not affect the functioning of reflex sensors.

The reflex sensor should be supplied with compressed air at port P. The air with a pressure of 1.5 to 3 psi / 0.1 to 0.2 bar must be filtered and free of any water or oil. If the jet, constantly emitting air, is disturbed by an object in front of the sensor, a signal pressure ≥ 0.007 psi / 0.5 mbar appears at outlet A. This signal pressure is then converted to a higher pressure by amplifiers.
