description
Optoelectronic ring light barriers have been designed to
monitor the material flow of small parts such as screws or
springs. Plastic parts or liquids (drops) can be reliably
recognized as well. Material can also be detected when it
is supplied through a transparent supply hose.
A light curtain is formed within the ring by several light
barriers. The corresponding amplifier converts the interruption of one light beam into a switch signal. This guarantees
the detection of very small objects above 1mm in diameter
(for OY106000). The amplifier is available in both a dynamic
and static version.
Using the dynamic amplifier parts can be detected, moving
quickly through the ring (e.g. free falling objects). An
advantage of the dynamic functional principle is the
automatic adjustment in case of variable environmental
conditions like soiling or scratching of the supply hose.
Typical uses are counting tasks or application in the feeding
technology for automatic assembly machines.

allows slow or static conditions to be recognized in addition
to fast movement sequences. The output stays in the
connected mode, as long as material can be found in the
active zone that needs to be detected. This version is used
to control e.g. the presence of liquids in a transparent plastic
hose.
It is possible to adjust the sensitivity of response using the
integrated potentiometer. The soiling of a transparent
supply hose may be compensated this way.
Another potentiometer has the function of stretching the
output pulse. This way the device may be adapted to the
requirements of a down-line control independent of the
speed of the object to be detected.
