PRMDC000产品概述
These miniature self-contained and powerful Retroreflective, Proximity (Diffuse) and Opposed Beam Pair Photo-electric Sensors provide application flexibility in counting, positioning and object detection. All units are interchangeable with conventional 12 mm threaded barrel-type photo-electrics and inductive proximity sensors. Their small size, in addition to various mounting options, greatly increases alignment ease and application possibilities. All units 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. Two versions of the sensor are available, a 6 foot (1.83 M) long 4 conductor PVC jacketed cable or 6 inch long quick disconnect Pico-style connector provides supply input and transitor output. These miniature sensors offer 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 LED's 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.
