Fife M431024 Web Edge Sensor

FIFE DSE-22
DIGITAL INFRARED LIGHT SENSOR
Because of its compact size and insensitivity to ambient light, the digital infrared sensor DSE - 22 is the ideal
solution for many applications where accurate web guiding is required.
The DSE - 22 Infrared Sensor measures the lateral position of the guided material photo electrically. The control
range (proportional band) allows significant guide point adjustment. The DSE - 22 is often used in pairs for
centre guiding when web width variations are limited. Its excellent technical specifications allow it to also be used with
a Fife processor to guide clear film. Normally the DSE - 22 is used for guiding opaque materials.
It is possible to operate the DSE - 22 with either a supply voltage of 12 V or 24 V. The output signal
would automatically be switched over in that case.
In 12 V supply mode the sensor provides an output signal from 0 to 10 mA and can be connected to all
available Fife web guide processors.
In 24 V supply mode the sensor supplies an output signal between 4 and 20 mA and can be easily
connected to a PLC as well.
The DSE - 22 has a built-in LED display, visible from both sides, and shows directly on the sensor
information about the operating status like for instance the existence of the supply voltage, position of
the edge of the web inside the field of view or error messages.
An optional digital production data acquisition to Fife D-MAXE controller extends the range of applications for the
DSE - 22 inside the digital network environment. Additional sensor data can be provided to other hardware equipment if
the Fife D-MAXE is linked appropriately to the network.
