Sensor Installation
The BFS 30M Color Sensor is provided with 2 jam nuts allowing it to be easily mounted thru a 30mm
clearance hole. The BFS 30M Color Sensor bracket provides a 30mm clearance hole for the sensor and a
pivot and slot for a #8 screw for mounting the bracket. The slotted hole allows the angle of the sensor to
target to be easily adjusted.
To achieve optimum performance it is recommended that samples be evaluated prior to permanent
installation of the sensor.
During evaluation, sensor-to-target distance and sensor-to-target angle can
easily be determined by placing samples into the sensor’s field of view and observing the RGB color
component signal levels. When possible, it is generally best to set the sensor at a target distance that
results in a signal level of 80% to 90% using the lightest sample. If necessary the illumination level may
be reduced to prevent the sensor from saturating on light colors.
Color I/O
The BFS 30M Color Sensor I/O board provides a means of connecting the sensor cable to other external
devices. The I/O board also provides a set of LEDs for each channel that indicates the status of the
discrete outputs for verification of sensor operation and color recognition. A modular jack (a phone style
plug) and cable are used to easily connect a PC to the sensor for programming. It is
not
necessary for
the BFS 30M Color Sensor I/O board to be used; all sensor connections may be routed directly to the
appropriate devices such as a PLC.
In addition to a power indicator LED, there are 2 LEDs associated with each channel. The LEDs are
arranged in 2 columns, one labeled PNP and the other labeled NPN. The PNP LED indicates that a
channel output is high, connected to sensor V+, while the NPN indicates that a channel output is low,
connected to sensor ground. Operation of the discrete channel outputs is dependent on whether the
Match output is set too high or low for a particular channel. Both PNP and NPN LEDs will be
illuminated for channels that are not connected to the BFS 30M Color Sensor I/O board.
