Encoders are sensors that read the position, movement, or speed of a motor shaft or machine part on a variety of applications. The EVE-RLCJL008B is a high accuracy, long life, and reliable incremental encoder that provides 32 cycles, 16 pulses per cycle starting from index A and B signals. This encoder is designed to work in a wide range of industrial settings. so its application field and working principle are very important for the users.

EVE-RLCJL008B Application Field

The EVE-RLCJL008B is mainly used in the motion control field of different industrial projects. It can be easily installed in printing, automatic lathe, textile and packaging machinery, handling devices, and other automated equipment. Because of its high accuracy it is specially designed to fit with high-precision and high-speed applications. It is applicable for either single speed or multi-speed applications.

The EVE-RLCJL008B is also suitable for use in highly demanding optical systems, such as Fiber Optics (FO) and Scan Imaging (SI). FO systems needs precise control of the optical fiber positioning for proper termination. Moreover, SI is the process of attaching a low-cost CCD camera and lenses onto a moving object, because it needs repeatable and consistent tracking to produce clean images. on both cases the EVE-RLCJL008B is able to precisely provide feedback with its highly reliable output.

EVE-RLCJL008B Working Principle

The EVE-RLCJL008B encoder works on the principle of incremental detection. This principle is based on the recognition of the sequence of tone wheel (or disk) teeth that pass in front of a light-emitting diode (LED) or an infrared (IR) LED, specially designed for the purpose. As the tone wheel turns, it generates an optical signal, which is then picked up by the LED or IR LED. This generates a series of pulses referred to as increment signals, thus the name, Incremntal Detection.

A signal channel uses two ICs (Integrated Circuits) to form an optical switch. The signal is processed by the IC to output a single pulse which will correspond to one tooth/slot from a tone wheel. The EVE-RLCJL008B generates two phases (A and B) with 16 pulses/cycle so that they can be used for direction detection. The pulse frequency is proportional to the shaft rotational speed.

The EVE-RLCJL008B has a push-pull circuit that can detect the stable direction from the A and B phases. Push-pull circuits are useful for canceling undesired interference from nearby electrical circuit. This gives the EVE-RLCJL008B a high noise immunity and high EMI resistance, making it suitable for noisy and harsh industrial environments.

Conclusion

The EVE-RLCJL008B is an incremental encoder that offers high accuracy, reliability, and long life. It is mainly used in motion control systems for industrial applications such as printing, automatic lathe, textile and packaging machinery, and handling devices. It works on the principle of incremental detection, which relies on generating a sequence of pulses from a tone wheel or disk that is passed in front of an LED or IR LED. This enabled it to offer both speed and direction detection. It also comes with a push-pull circuit that helps make it more resistant to noise and EMI levels.
