The HEDS-5140#A12 are quad digital optical encoders manufactured by Avago Technologies. These encoders are used in a wide range of applications in many industries, such as medical, automotive, industrial manufacturing, semiconductors, consumer electronics, and robotics. The HEDS-5140#A12 come in a compact footprint and offer multiple resolutions for various applications.

The HEDS-5140#A12 offer a variety of features for various applications. They come with four digital outputs, which allow for higher resolutions and improved accuracy. They also include extended temperature range, which allows for a wider range of applications. Additionally, they are capable of operating over a wide operating voltage range.

The working principle of the HEDS-5140#A12 is based on a “code wheel” which is the disk pattened with concentric circles divided into a number of slots that are read by a compatible optical encoder head. On one side of the handle is an optical source which shines an infrared light onto the disk code wheel. This produces a binary pattern of binary bits on the disk code wheel. The optical encoder head detects the pattern of binary bits using a central photo-diode and four photo-diodes organized so that the light from the optical source is focused to the different photo-diodes. As the disk code wheel rotates, the light incident on the photo-diodes changes in a known sequence. The device then determines the pattern of binary bits for each encoder and outputs the appropriate digital signal.

The HEDS-5140#A12 enable precise measurement of changes in the rotational speed and/or a rotational angle by counting up the number of slots on the disk code wheel with a high resolution. This is made possible thanks to the high resolution provided by the current versions of the encoders, which can scale up to 24,000 counts per revolution. The HEDS-5140#A12 also provide exceptional accuracy, with the ability to detect linear movements up to 0.1 micrometer.

The HEDS-5140#A12 quad digital optical encoders are used in a multitude of industries for applications that rely on the precise measurement of rotational speed or angle. This includes automated device control, the precision positioning of components, robotic arms, and medical devices such as endoscopes. The encoders are also used for navigation and guidance in the automotive and aerospace industries. With its high resolution and extended temperature range, the HEDS-5140#A12 is an ideal solution for many applications.
