Optical Sensors - Reflective - Logic Output are widely used in diverse applications such as non-contact sensing, adjustable threshold sensing, range control and object detection. The AEDR-8400-140 is a reliable and highly accurate logic output sensor from a family of such sensors. Here, we discuss the application fields and working principle of this device.

The sensor is basically designed for detecting the presence or absence of objects in industrial and commercial applications. It is characterized by its high accuracy, repeatability, extended sensing range, and the fact that it can operate in demanding environments. The device is widely used in industrial settings for non-contact sensing of objects and adjustable threshold control. In commercial settings, it is used to detect the presence or absence of objects, such as bottles or jars, for applications such as vending machines, mail processing, conveyor belts and baggage handling. The device is also used to monitor production processes for completing tasks involving range control, object location and detection.

The AEDR-8400-140 uses advanced refractive light technology combined with an optical filter to detect the presence or absence of objects, including opaque and transparent objects, within a 100 mm sensing range. The active area of the sensor is illuminated with visible red light and a photodiode receives the reflected light from the object. A highly accurate 4-bit DAC (digital-to-analog converter) allows the sensitivity to be adjusted to any distance between 0 and 100 mm. The logic output is correlated to the light received. When the light received is above the sensed threshold, an NPN output is actuated.

Thanks to its highly accurate 4-bit DAC, the AEDR-8400-140 is particularly reliable and precise. This sensor operates without false triggers due to temperature drift and other environmental conditions. Thus it provides superior performance and repeatability even in the most demanding industrial applications. Furthermore, this device is protected by a rugged housing with an M12 screw terminal, making it suitable for use in wet or dusty environments.

Overall, the AEDR-8400-140 is an excellent choice for any industrial or commercial application requiring highly accurate object detection and range control. It is reliable and robust, and its advanced refractive light technology enables consistent and repeatable operation in a wide variety of operating conditions. Its adjustable threshold sensing, extended sensing range and feedback circuitry make it an ideal choice for applications involving range control, object detection and adjustable threshold sensing.
