Optical sensors are one of the most commonly used sensors in the industry for multiple applications, such as detection of speed, object presence, short object lengths, and direction. Photointerrupters, also known as reflective metal-oxide sensors, are an integrated type of optical sensor, typically coupling a light source such as an LED and a light-sensitive element such as a photodiode or phototransistor. Slot type photointerrupter sensors are best used for larger objects such as cardboard boxes, and offer higher sensitivity for the detection of objects that are wider and longer than the slots designed in the interrupter. Logic output photointerrupters are the ideal choice for applications that require an assured level of accuracy, yet demand a relatively small form factor. One such product of note is the OBP982N51 from Optocore.

The OBP982N51 is a mini-slot type logic output photointerrupter, offering precise detection with reliable operation over a wide range of temperatures and environmental conditions. In order to achieve this, the OBP982N51 combines a high-brightness emitter and a phototransistor, which are connected in an inverse-parallel configuration. This design allows for rigorous detection of normal objects, spaces, and timing as the object is detected by the crossed paths of the emitter and the phototransistor. The logic output allows for switching according to object-presence detection, and is designed for use in various electronic control systems.

The OBP982N51 has a wide range of applications, including robotics, motion control, and industrial automation. It can be used to detect plastic cards and ID cards, as well as to determine the presence or movement of rotating disks. It is especially useful in environments where precise, long-term motion detection is necessary, such as mechanical systems and robotics. When used in combination with an encoder or a resolver, the OBP982N51 can accurately measure rotational speed and position, allowing for more streamlined automation processes.

The OBP982N51 is designed to operate under a variety of environmental conditions, from -20°C ~ +80°C. It is constructed with a high-transmittance reflector, allowing for detection and resolution of wide objects, even in low-light conditions. It offers high reliability with respect to its resistance to mechanical vibration and electrical noise, and its low power requirement makes it ideal for embedded applications. The OBP982N51 is RoHS compliant, meeting all the necessary environmental standards.

In conclusion, the OBP982N51 is a high-performance, reliable, and cost-effective logic output mini-slot type photointerrupter for use in a wide range of applications. Its precise sensing capabilities, along with its optimized performance, make it an ideal choice for a variety of industrial and commercial automation projects or electronic control systems.
