MINI-BEAM
The sensor’s Gain adjustment and Light/Dark Operate switch are located
under the gasketed acrylic cover. Loosen the screw to access these
adjustments and use a small screwdriver to adjust.
Gain adjustment:
Turn clockwise to increase gain (sensitivity); 15-turn Gain potentiometer is
clutched at both ends of travel.
Light/Dark operate selection:
• Turn switch fully clockwise for light operate (sensor outputs conduct
• Turn switch fully counterclockwise for dark operate (sensor outputs
Unterminated plastic fibers are designed to be cut by the user to
the length required for the application. To facilitate cutting, a
Banner model PFC-1 cutting device is supplied with the fiber. Cut
the fiber as follows:
1) Locate the “control end” of the fiber (the unfinished end).
2) Double-check the fiber length, and close the cutter until the fiber
3) Gently wipe the cut ends of the fiber with a clean, dry cloth to remove
1) Unlock the fiber gripper as shown in figure 3. If 0.25 mm or 0.5 mm core
2) Gently insert the prepared plastic fiber ends into the ports, as far as they
3) Slide the fiber gripper in to lock, as shown in figure 3.

Determine the length of fiber required for the application. If
using a bifurcated fiber, separate the two halves of the fiber at
least 2" beyond the fiber cutting location. Lift the top (blade) of
the cutter to open the cutting ports. Insert one of the control
ends through one of the cutting ports on the PFC-1 cutter so
that the excess fiber protrudes from the back of the cutter.

to the required length. To ensure a clean cut each time, do not
use a cutting port more than once.
