Encoders

HEDS-5701#H12 is a very popular precision optical encoder system used in many industries and applications. It is used to provide feedback information about rotation and speed or the position in an electric or mechanical drive system.

Application Field

HEDS-5701#H12 is ideal for applications that require speed control, linear or angular position, and low-cost, low-power, and durability. It is used in medical instruments, consumer electronics, electrical appliances, aerospace and defense systems, industrial automation, automotive electronics, and machine tools and manufacturing equipment. It is also used in motion control and positioning applications.

HEDS-5701#H12 performs well in applications that require a durable and highly accurate optical encoder that can accurately detect motion even in challenging environments. Its smaller size allows it to be used in tight spaces and its higher accuracy enables it to detect small, rapid changes in motion. Additionally, its rugged construction and high-temperature housing allows it to be used in high-thermal shock applications.

Working Principle

HEDS-5701#H12 consists of an integrated optical encoder module, a light source, an optical code disc, an optical detector, an encoder body, and a signal processing circuit. The optical encoder module transmits modulated digital pulses and transmits them as an output signal.

The main components of the optical encoder are the light source and the optical code disc. The optical code disc is usually made of metal with a micro-optical structure engraved on it. It contains narrow, opaque bars and slots called “code tracks”. The light source emits a light beam which passes through the code tracks, reflecting the light back to the opto-detectors in the module. The optical detector receives the reflected signal and a circuitry inside the detector converts it to an electrical signal. This signal contains data information about the direction, magnitude, and angle of rotation.

The signal is then transferred to the signal-processing circuitry, which decrypts the data and converts the signal to digital or analog format depending on the application. The signal can then be read by the controlling device for further control and feedback information.

Conclusion

HEDS-5701#H12 can be used for a variety of applications due to its accuracy, robust design, and size. It is ideal for high-accuracy motion or speed detection, particularly in harsh environments. Its signal processing circuitry decodes data efficiently and the outputs can be used for further applications such as controlling servo-motors or stepper motors.
