How optical encoders can optimize your interaction with tech

Optical encoders and transducers enable users to translate information from one code to another. Optical encoders come in different varieties including rotary encoders and linear encoders. The optical rotary encoder is used in motion control systems, whereas linear encoders are used with linear-positioning systems like actuator monitoring systems or pistons. The rotary encoder is advanced due to its ability to use optical sensing technology that heavily relies on the rotation of the internal code disc. The disc is rotated to generate a response, has patterns and lines on it, and when an LED is shone on it, the disc blocks and unblocks the light. The light beams are detected by the internal photo-detector and the encoder’s electronic counterparts transform the light pattern into electrical signals that are shuttled toward the encoder’s output and the external control panel. Linear encoders are useful for linear-positioning systems.

Other types of rotary encoders are called absolute and incremental, and can be built with a shafted or hollow shafted body. Incremental optical encoders are widely integrated in various technologies. This encoder delivers data about the position of the revolving shaft and emits one square wave for every shaft movement. When compatible, the optical encoders fit into the internal hardware system of the device. Absolute optical encoders contain an intricate signal structure providing output with a special code pattern that comes from separate tracks located on the encoder disc. The photo-detectors signify the specific positions. The code disc pattern that results is HI or LO contingent on the positions.

Avago Tech has an array of options when you’re looking for extraordinarily functional encoders. This company is a renowned supplier and a veteran in the industry, present in encoder module market for over 25 years. From motion control optical encoders to magnetic encoders and more, Avago Tech is fully stocked with a variety of encoders including incremental encoders and absolute encoders for motor feedback and positioning systems. All of Avago Tech’s incremental encoders and absolute encoders fit the rigid requirements of velocity sensing and positioning systems. These high-tech products are used in a wide range of devices, including printers, robotic arms, copiers, scanners to servo and stepper motor feedback systems, and wafer-handling machines. In the department of industrial automation, Avago Tech also has you covered.

Avago also supplies housed encoders and kit encoders for users that need to upgrade from the US Digital kit. Encoders like the US Digital E2 Series and the US Digital E5 Series can be switched out with Avago’s encoder kits. Avago’s HEDC-55xx/56xx Series can be implemented when replacing the US Digital E5 Series kit encoders. Other replacement options for Renco encoders like the RCML15, R22i, and the R35i are also available. 

To coincide with its encoder products, Avago’s accessories like alignment tools, cables, code wheels, and connectors will benefit your tech projects. Products such as controllers, decoders, and photo interrupters will suit your technological needs.
