Encoders: HEDS-5505#A13 Application Field and Working Principle

Encoders are electromechanical devices that convert an input signal into an encoded output signal. HEDS-5505#A13 is a precision dual-output optical incremental encoder from Broadcom Limited.

Application Field

HEDS-5505#A13 is used in a variety of industries and applications, such as robotics, automated inspection, factory automation, automotive production, computer-controlled motion control, and test and measurement. It is also used in consumer electronics, such as remote controls, game controllers, digital cameras, and imaging systems. In addition, the encoder can be used in medical, aerospace, and military applications.

Working Principle

The HEDS-5505#A13 encoder is based on the principle of optical incremental encoding. The encoder has two output signals, A and B. These signals generate a rectangular waveform, whose frequency is proportional to the rotational speed of the shaft. The output signals can be further processed by a control system to obtain a relative position. The encoder has an optical scanning system composed of a light source, an integrated photodetector, and a gray code disk with slots and idlers. The photodetector emits light that is reflected and scattered by the slots and idlers to generate two signals, A and B. The signals are pre-indexed and generated according to the format of the Gray code or Binary code. The signals are used to calculate the direction of the rotation and the number of pulses. The encoder also has a zero-index output, allowing the control system to reset the position data to zero.

Construction

The HEDS-5505#A13 encoder is a robust device designed to last up to 5 million cycles of use. It is constructed using heavy-duty ceramic materials, and is designed to withstand shock and vibration. The housing is sealed to protect the sensitive optical elements from dust, water, and other environmental contaminants. The encoder is also equipped with two locking devices, one on the I/O terminal and another on the back, to ensure that the wiring remains secure and tight.

Advantages

The HEDS-5505#A13 encoder is an excellent choice for applications requiring high accuracy. The device is extremely accurate, with a resolution of up to 32 counts per revolution. It is also able to compensate for variations in shaft speed and radial runout. The internal mechanical components are protected by the strong housing, allowing it to operate reliably in rough environments. Furthermore, it is very easy to wire and configure, making it simple to integrate into existing systems.

Conclusion

The HEDS-5505#A13 encoder has a wide range of applications in various industries. It offers excellent performance, accuracy, and reliability, making it a great choice for industrial automation and motion control applications. The robust construction and easy-to-use features make it a great value for money.
