MINI-BEAM SME312 Expert Series
Instruction Manual
Microprocessor-Based TEACH Mode Photoelectric Sensors
•
•
TEACH-mode sensors in the popular MINI-BEAM package
Easy push-button programming automatically adjusts sensitivity to optimal
setting
•
Multiple sensing modes include retroreflective, polarized retro, clear object
detection, diffuse, divergent, and convergent, plus glass and plastic fiber
optic models
•
•
•
Fast, 500 microsecond (0.5 millisecond) output response
Bipolar NPN (sinking)/PNP (sourcing) outputs
Easy output programming eliminates the need for Light or Dark operate
selection
•
•
•
•
Separate TEACH input allows remote programming by an external device,
such as a switch or process controller
LED status indications for received signal strength (using Banner's AID
function), power ON, and output state
Green Stability indicator flashes when received signal level approaches the
switching threshold, also indicates Power ON
™
U.S. patent(s) issued or pending
Integral 2 m (6.5 ft) cable or 5-pin Euro-style quick-disconnect (QD)
connector, depending on model; 9 m (30 ft) cable models are also available
WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to
serious injury or death. This device does not include the self-checking redundant circuitry necessary
to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an
energized or de-energized sensor output condition.

Standard 2 m (6.5 ft) cable models are listed. To order the 9 m (30 ft) cable model, add suffix “W/30” to the model number (for example,
SME312LV W/30.) To order the 5-pin Euro-style QD models, add suffix “QD” (for example, SME312LVQD). Models with a QD connector require a
mating cable.
Sensing ranges vary according to the efficiency and reflective area of the retroreflector(s) used. (Retroreflective tape is not recommended for use
with Clear Object Detection models.) See Accessories and the Banner Engineering catalog for more information.
