Encoders are devices used to measure rotary and linear motion. HEDS-9701-C51 encoder is a digital optical encoder made by Avago Technologies. It is a quadrature gray code encoder consisting of two main components: the detector and the code disk. The detector contains four lighted slits with four phototransistors that detect the feedback from the disk, while the code disk is embedded with data in a pattern of gray code segments. This encoder is designed to be used in home electronics, office equipment, communication and medical applications.

HEDS-9701-C51 application field and working principle

HEDS-9701-C51 encoders are designed for accurate detection and measurement of rotary and linear motion. They are widely used in many different types of automated and integrated systems and applications. Common applications include: home appliances, machines, automotives, medical equipment, construction equipment, and many others. These applications involve precise and reliable tracking of distance travelled, feedback control, and positioning.

The HEDS-9701-C51 encoder uses a gray code wheel with patterns of reflecting surfaces to achieve accurate positional information. The code wheel is designed with a series of tracks which allow an optical detector to read the pattern of the wheel and detect the differences between its brightest and darkest sections. As the wheel is rotated, the code disk sends a unique gray code pattern which is then detected by the attendant detector. The detector then creates pulses at a fixed frequency which is used as the encoder’s output.

The operation of the encoder is dependant on a few factors, such as the resolution, the number of tracks, and the voltage. The resolution of the encoder is determined by the number of tracks on the code disk and the number of segments on each track. The higher the number of tracks and segments, the higher the resolution and greater accuracy of the encoder. Additionally, different voltages are used for various applications. Most HEDS-9701-C51 encoders operate at 5V, however they can be set up to work with 3V, 6V, and 12V.

The outputs from the encoder depend on the type of system being used. For example, a differential output provides two signals which can be used for position sensing, whereas a single output provides only one signal which can be used to determine speed, direction, or position. Additionally, the outputs can be encoded as pulse train data, quadrature signals, frequency data, and direction signals.

HEDS-9701-C51 is a versatile encoder that offers a combination of cost-effectiveness, accuracy, and reliability. In many applications, these encoders are used for a variety of tasks such as position and motion measurement, feedback control, and closed-loop motion control. They are used in consumer electronic products such as vacuum cleaners, demand-driven automated machinery, and customized solutions for demanding industrial applications.

The HEDS-9701-C51 encoder is a reliable and cost-effective solution for precise detection and measurement of rotary and linear motion. Its accuracy and flexibility make it suitable for many different applications. Its ability to generate a wide range of output signals makes it equally versatile in both complex and simple systems. Through its compact design, the HEDS-9701-C51 encoder provides a powerful, flexible, and effective means of measuring both rotary and linear motion.
