Mount the Device
1. If a bracket is needed, mount the device onto the bracket.
2. Mount the device (or the device and the bracket) to the machine or equipment at the desired location. Do not tighten the
mounting screws at this time.
3. Check the device alignment.
4. Tighten the mounting screws to secure the device (or the device and the bracket) in the aligned position.
Sensor Alignment
Note: Follow proper electronic shock discharge (ESD) precautions when adjusting the Gain potentiometer or the
LO/DO switch.
Note: When turning the Light/Dark Operate Select switch, be careful not to damage the small tabs on the
switch.
1. Using line-of-sight, position the MINI-BEAM sensor to its emitter (opposed-mode sensing) or to its target (all other sensing
modes).
When using a retroreflective sensor, the target is the retroreflector (“retro target”). For diffuse or convergent sensing
modes, the target is the object to be detected.

2. Apply power to the sensor (and to the emitter, if using the opposed mode).
3. Using a small, flat-blade screwdriver, turn the 15-turn Gain control to maximum (the clockwise end of rotation).
The Gain control is clutched at both ends to avoid damage, and will “free-wheel” when either endpoint is reached.
If the MINI-BEAM sensor is receiving its light signal, the red LED Alignment indicator is ON and flashing at a rate
proportional to the signal strength (a faster flash rate = more signal).
4. Move the sensor (or move the retro target, if applicable) up-down-right-left, including angular rotation, to find the center of
the movement zone within which the LED indicator remains ON.
Reducing the Gain setting reduces the size of the movement zone and enables more precise alignment.
5. Repeat the alignment motions after each Gain reduction.
6. When optimum alignment is achieved, mount the sensor, and the emitter or retro target, if applicable, securely in that
position.
7. Increase the Gain to maximum.
8. Test the sensor by placing the object to be detected in the sensing position, then removing it.
The Alignment indicator LED turns ON when the sensing beam is established (Light condition), and turns OFF when the
beam is broken (Dark condition). If the Alignment indicator LED stays ON for both sensing conditions, see the following tips
for each sensing mode.
Opposed Mode Alignment

Ob
Emitter
Flooding occurs when a portion of the sensing beam passes
around the object to be sensed. Burn-through occurs when a
portion of the emitter’s light energy passes through a thin or
translucent object, and is sensed by the receiver.
To correct either problem, do one or more of the following to
reduce the light energy:
• Reduce the Gain adjustment on the receiver
• Add an aperture to one or both lenses (MINI-BEAM
apertures, available from Banner, fit neatly inside the
lens assembly)
• Intentionally misalign the emitter and receiver
t

•
Light condition: sensor output is

Dark condition: sensor output is ON

Diffuse Mode Alignment
t
jec
Ob
If the Alignment LED does not go OFF when the object is
removed from the beam, the sensor is probably detecting light
reflected from some background object. To remedy this
problem:
• Reduce the reflectivity of the background by painting
the surface(s) flat-black, scuffing any shiny surface, or
drilling a large hole, directly opposite the diffuse sensor
• Move the sensor closer to the object to be detected and
reduce the Gain adjustment. Rule of thumb for diffuse
sensing: The distance to the nearest background object
should be at least three times the sensing distance

MINI-BEAM® AC Voltage Series Sensor
Retroreflective Mode Alignment
A highly reflective object may reflect enough light back to a
retroreflective sensor to allow that object to slip through the
beam, without being detected. This problem is called proxing,
and the following methods may be used to correct it:
• Position the sensor and retro target so the beam will not
strike a shiny surface perpendicular to the sensor lens
• Reduce the Gain adjustment
• Add a polarizing filter (for model SM2A312LV)

Convergent Mode Alignment
The sensing energy of a convergent mode sensor is
concentrated at the specified focus point. Convergent mode
sensors are less sensitive to background reflections, compared
with diffuse mode sensors. However, if background reflections
are a problem:
• Skew the sensor position at a 10° to 25° angle to
eliminate direct reflections from shiny background
surfaces
• Reduce the reflectivity of the background by painting
the surface(s) flat-black, scuffing any shiny surface, or
drilling a large hole, directly opposite the sensor
• Reduce the Gain adjustment

Installing the Glass Fibers in MINI-BEAMs
Retaining Clip
O-ring
1. Install the O-ring (supplied with the fiber) on each fiber end, as shown in the drawing.
2. While pressing the fiber ends firmly into the ports on the sensor front, slide the U-shaped retaining clip (supplied with the
sensor) into the slot in the sensor's barrel, until it snaps into place.

Installing Plastic Fibers on a MINI-BEAM
Follow these instructions to install plastic fibers into your sensor. MINI-BEAMS may have either a fiber gripper or a clamp screw.
MINI-BEAM and ECONO-BEAM sensors for use with plastic fiber optic assemblies include sensors with the letters FP in their
model number.

Figure 2. MINI-BEAM with clamp screws
1. Prepare the sensor ends of the fibers (see Cut the Plastic Fiber on p. 5).
2. Prepare the sensor for the fibers.
• For models with a fiber gripper: Unlock the fiber gripper as shown in the figure and apply the appropriate fiber adaptors
to the fiber, if needed.
• For models with a clamp screw: Loosen the clamp screw on the sensor face.
3. Insert the plastic fibers.
• For models with a fiber gripper: Gently insert the prepared fiber ends into the ports as far as they will go.
• For models with a clamp screw: Align the fiber ends flush with the ends of the bushings as shown. Hold the bushings to
the fibers and slide both into the sensor ports. Push the fiber an additional 1 inch through the bushing.
4. Lock in the fibers.
• For models with a fiber gripper: Slide the fiber gripper back to lock, as shown in the figure.
• For models with a clamp screw: Tighten the clamp screw to secure the fibers.
Cut the Plastic Fiber
An unterminated plastic fiber is designed to be cut by the customer to the length required for the application. To facilitate cutting, a
Banner model PFC-4 cutting device is supplied with this fiber.
1. Locate the non-terminated end, and determine the length of fiber required for
the application.
2. Lift the top of the cutter to open the cutting ports.
3. Insert the non-terminated end through one of the four large cutting ports on the
PFC-4 cutter so that the excess fiber protrudes from the back of the cutter.
4. Double-check the fiber length, and close the cutter until the fiber is cut.
5. Gently wipe the cut ends of the fiber with a clean, dry cloth to remove any
contamination.
Note: Do not use solvents or abrasives on any exposed optical
fiber. Do not use a cutting port more than once. The blade may
tend to dull after one cut.

Application Notes
Overload conditions can destroy ac MINI-BEAM sensors. Directly wiring
sensor without load series, across hot and neutral will damage sensor
(except emitter models).
Low-voltage use requires careful analysis of the load to determine if the
sensor’s leakage current or on-state voltage will interfere with proper
operation of the load.
The false-pulse protection feature may cause momentary drop-out of the
load when the sensor is wired in series or parallel with mechanical switch
contacts.
Note: 300 millisecond delay on power-up.

Opposed-mode MINI-BEAM sensors may be fitted with apertures that narrow or shape the effective beam of the sensor to more
closely match the size or profile of the object to be sensed, for example, the use of “line” (or “slit”) apertures for sensing wire or
thread. Each model contains 20 apertures.
