Microprocessor-Based TEACH Mode Photoelectric Sensors

U.S. patent(s) issued or pending

•

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

•

function), power ON, and output state

•

Green Stability indicator flashes when received signal level approaches the

switching threshold, also indicates Power ON

•

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.

1 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.

2 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.
