Specialized Sensors are modern sensing devices designed to detect specific physical phenomena and parameters. As such, they are particularly useful in various industries and domains, such as industrial automation, robotics, and other precision-intensive fields. In this article, we will discuss the application field and working principle of CR6221-250-20, a specialized sensor.

CR6221-250-20 is an infrared linear array array developed and manufactured by AMS AG. This miniature, highly integrated, and custom 2nd-gen shortwave sensor is designed for precision motion detection, distance or range sensing, and smart robotics applications. The package size of CR6221-250-20 is only 3x3x1.35 mm, making it an ideal choice for size-constrained applications.

The linear array is composed of 256 pixels with a pitch of 250 µm, and a sensing range of 50 cm. It features integrated analog to digital conversion, permitting extremely precise and accurate distance and range sensing. With a frame rate of 25 frames per second, CR6221-250-20 is able to accurately detect movement in a field of view measuring up to 10 cm. The linear array has a power consumption of 6 mW, a voltage supply range of 3V to 5.5V, and a dark current of less than 0.2µA.

CR6221-250-20 is a good choice for applications requiring accurate distance sensing and motion detection, such as robotic arms, automated sorting systems, drones, and smart home appliances. For example, it can be used to detect objects, measure distances and ranges, and monitor movement. It can be integrated into various robotic systems for myriad purposes, including navigation, collision avoidance, and even bin-picking.

In terms of working principle, CR6221-250-20 works by detecting the absorption of infrared radiation. It consists of an array of 256 sensors which absorb infrared radiation and convert it into electrical energy. The sensors measure and map the intensity of the radiation that they receive. The output signals are then processed to determine the positional information and motion of the objects within the sensing range. As the object moves, the signals will change, allowing the system to detect and track the motion.

CR6221-250-20 is a versatile and powerful specialized sensor suitable for a wide range of applications. Its high precision and accuracy make it ideal for precise distance and range sensing, motion detection, and robotics. As it is small in size and requires low power, it can easily be integrated into systems. Its unique design and working principle allow it to accurately detect objects and motion, making it an indispensable component of smart systems.
