Photosensors
The photosensors use a high-powered LED
pulse output to detect items. When an item
is present, this beam is reflected back into a
sensitive detector built into the photosensor. A
signal is then sent to the I/O control panel.
There are numerous photosensor located at
various places around the unit (Figures 5-7, 5-
8). The table on the pages following the pictures
provide information about each photosensor.
Proximity Sensors
The proximity sensors use a magnetic field to
detect the position of machine components. When
a mechanism is in the proper position, this is
detected by the disturbance of the magnetic field.
A signal is then sent to the I/O control panel.
There are numerous proximity sensors located
at various places around the unit (Figures 5-7, 5-
8). The table on the pages following the pictures
provide information about each proximity
sensor.
