These economical single-unit sensors are excellent for sensing objects of adequate size
and reflectivity at short range. Divergent models are useful for sensing small items and
translucent or transparent materials at close range.The SME312DV sensors effectively
sense specular surfaces like smi-conductor wafers, disk drive media, glass and machined
surfaces. The collimated optics of the SME312DV also permits the sensor to be mounted
against clear container walls, view ports and other types of optical “feed-throughs.”

An excellent option for sensing in tight or otherwise inaccessible areas. Fibers
withstand vibration and shock; are immune to electrical noise. Plastic fibers
function well at temperatures from -30º to +70ºC (-20ºF to +158ºF), and stand up
to repeated flexing. Most are easy to shorten in the field, for custom installations.
Not recommended for severe environments (see glass fiber models). Visible
green,blue and white beam models are recommended for color mark sensing.

Using the MINI-BEAM Expert
RUN Mode
Normal operation of the MINI-BEAM Expert is called RUN mode. The two LED
indicators (bi-color Green/Red and Yellow) operate as follows in RUN Mode:
Green (RUN Mode): ON steady whenever power is applied
Flashes as received light level approaches the switching
threshold (stability indicator). (The stability indicator
signals when maintenance, realignment, or
reprogramming is needed during RUN mode.)
Yellow (Output): ON when the outputs are energized (conducting)
OFF when the outputs are de-energized (not conducting)
If contrast is marginal, the bi-color indicator will flash green (to indicate
instability). Reprogramming or realigning the sensor, or cleaning the sensor or
fiber lenses may solve a problem with stability.
TEACH Mode
Programming of the MINI-BEAM Expert – setting the sensitivity and selecting output
ON and OFF conditions – is performed in TEACH mode.
Determining the Output ON and OFF Conditions
The two sensing conditions may be presented in either order. The condition presented
first is the condition for which the output will energize (the “Output ON” target).
Setting Sensitivity
Sensitivity is automatically set (and optimized) when teaching the sensor the ON and
OFF conditions. When the push button is clicked, the sensor samples each sensing
condition and registers it into memory. After the second sensing condition is registered,
the MINI-BEAM Expert automatically sets the sensitivity to the optimum value for the
application, and then returns to RUN mode.
The two LED indicators (bi-color Green/Red and Yellow) operate as follows in
TEACH Mode:
Red (TEACH Mode): Lights when the sensor “sees” its modulated light source;
pulse rate is proportional to the received light signal strength during TEACH
programming
Yellow (Output): ON to indicate TEACH output ON condition
OFF to indicate TEACH output OFF condition
The Signal Strength indicator is Banner’s exclusive AID™(Alignment Indicating
Device). Its pulse rate increases as the received light signal strength increases (during
programming). This feature simplifies accurate alignment during TEACH mode, and
gives a relative indication of sensing contrast between the light and dark conditions.

If contrast is acceptable, the sensor returns to
RUN mode, otherwise it will return to TEACH
Condition #1.
Green: ON (or flashes if signal is close to the
switching threshold).
Yellow: OFF, until the sensing condition changes.
†NOTE: The sensor will return to RUN mode if the first TEACH condition is not registered within 90 seconds. TEACH mode may be cancelled
before either condition #1 or #2 by holding the push button depressed for ≥2 seconds.
A Note About the “Clicks”: Clicks are meant to be pressed firmly,
then quickly released. Indicators go ON or OFF after a brief delay;
do not wait until LEDs change status before releasing push button.
(If push button is pressed for 2 seconds or longer, sensor will
automatically return to RUN mode.)
Remote Programming
The gray wire of the MINI-BEAM Expert may be connected to a
remote switch or process controller to disable or enable the push
button or to program the sensor through TEACH mode.
A remote programming switch is connected between the gray wire
and dc common (see hookup diagrams on page 11). The switch
may be either a normally-open contact, or an open-collector NPN
transistor with its emitter connected to dc common.
Programming is accomplished using a specified sequence of
input pulses. The duration of each pulse is defined as:
0.04 seconds < T < 0.8 seconds.
The required spacing between adjacent pulses in a sequence
(a “four-pulse”) is also: 0.04 < T < 0.8 seconds. The timing
diagrams (Figure 2, left) illustrate the input requirements.

Banner Engineering Corp. • Minneapolis, U.S.A.
Website: http://www.baneng.com • Tel: 763.373.6767
TEACH-Mode Programming Using the Remote TEACH Line
NOTE: Pulse the TEACH line by momentarily connecting the remote wire to dc common
(no press-and-hold procedure is required to enter TEACH mode). This is the
equivalent of a “click” when using the sensor TEACH
push button.
1. Position the “Output ON” condition and pulse the Remote TEACH line once. The bi-
color (green/red) indicator begins to flash red or turn OFF (the AID function is
indicating signal strength) and the yellow Output indicator will flash briefly and then
go OFF.
2. Position the “Output OFF” condition and pulse the Remote TEACH line again. The
green indicator will turn ON and the sensor will return to RUN mode with the new
settings, if the contrast is adequate. If the contrast is not adequate, the yellow
indicator will turn ON and the red AID indicator will remain active, indicating that the
sensor is waiting for the first TEACH condition to be retaught. (RUN mode begins a
few seconds after the end of
TEACH mode.)
NOTE: To exit TEACH mode without updating, hold the Remote TEACH line low
(longer than 2 seconds) until the green indicator goes ON, before teaching the
second target.
Locking Out (Disabling) the Push Button
When remote programming is used exclusively, it may be beneficial to disable the push
button on the MINI-BEAM Expert to increase the security of the settings. The push
button can be enabled and/or disabled via the remote line only. If the push button is
disabled, TEACH mode cannot be accessed from the push button.
Pulse the Remote TEACH line 4 times (four-pulse) to enable or disable the push button
(see timing diagram, Figure 2).
Troubleshooting
The MINI-BEAM Expert’s Power LED may begin to alternate flashing red/green; this
indicates a microprocessor memory error. If it occurs, try reteaching the sensor, or try
cycling power ON and OFF, then reteaching the sensor. If this does not solve the
problem, or if it occurs frequently, replace the sensor.

Accessories
Banner offers a wide selection of high-quality retroreflective targets. See your current Banner
Photoelectric Sensors catalog for complete information on available models.
Polarized sensors require corner cube type retroreflective targets only. Sensing range will vary,
according to the efficiency and reflective area of the retroreflector(s) used. For these low-
contrast applications, the model BRT-2X2 (2" x 2") reflector is recommended, and one is bundled
with each SME312LPC(QD) sensor.
• For applications that involve high levels of vibration, the model BRT-36x40BM, with its micro-
prism geometry, is recommended.
• For long-range applications, the BRT-77X77C reflector provides a range up to 2 m (6.5').
• SME312LPC(QD) are for use with corner cube type reflectors only; reflective tape is not
recommended.
• For clear object detection (low-contrast applications), the model BRT-2x2 reflector is
recommended.
Before installling retroreflective tape, clean the surface with an isopropyl alcohol wipe.
