The Models EMMDC (Emitter) and the RCMDC (Receiver) are miniature, DC powered, Opposed Beam photo-electric sensor pairs with a 13 foot sensing range. The Emitter contains a high power modulated infrared LED. The Receiver contains a sensitive photo-transistor, amplifier-demodulator and output transistor. In operation, this output will be triggered when the Receiver detects that an object begins to break the Emitter beam. Due to their high gain, they are ideally suited for detecting opaque objects in dirty and dusty areas or when condensation or oil film environments are present.
The sensor provides application flexibility in counting, positioning and object detection. The unit is interchangeable with conventional 12 mm threaded barrel-type photo-electrics and inductive proximity sensors. The small size, in addition to various mounting options, greatly increases alignment ease and application possibilities.
The unit can be powered by supplies ranging from +10 to +30 VDC and are reverse polarity protected. The complementary NPN open collector (Current Sinking) outputs are protected from continuous overload and inductive load transients and are rated to 150 mA, with low saturation voltage and less than 10 µA off-state leakage current. In addition, no false outputs are generated at power-up. The sensor has a 6 foot (1.83 M) long 4 conductor PVC jacketed cable which provides supply input and transistor output.
The miniature sensor offers a digital gain adjustment that uses a single sealed push button to streamline installation and setup. The user simply holds the button in to achieve maximum sensitivity, and then can click the button for seven decremental settings to fine tune for your application. They also feature smart new status indicators. Green and amber LEDs display operating status from three directions, indicate power on and light sensed and flash to signal maximum gain, gain reduced one increment and minimum gain conditions. You can tell operating status of your sensors at a glance.
