Encoders

Encoders are specialized devices that measure the position of a mechanical system using various types of signals, such as pulses, pulses per rotation, pulse width, or continuous rotation. They convert the mechanical motion of a shaft or wheel into a digital signal. This signal can be used to determine the position of the system and is a widely-used technology in a variety of industries.

The most popular type of encoder is the incremental encoder, which emits pulses as the shaft or wheel rotates. The pulse-on-pulse scheme is used typically in motors, and the pulse-on-notch scheme is used typically in robots. Incremental encoders can be further subdivided into single-ended and differential encoders. Single-ended encoders provide one output signal per channel of motion, while differential encoders provide two output signals per channel of motion. Single-ended encoders are more economical but less accurate and reliable than differential encoders.

Encoders can also use absolute signals, which provide an absolute position measurement at all times. The output is a digital number and the position measurement is always referenced to a predetermined starting point. Absolute encoders can be single-turn, multi-turn, and even cyclic. Single-turn encoders provide one digital number representing the current position of the encoder; multi-turn encoders provide two or more numbers that also indicate the direction and magnitude of the past number of rotations; cyclic encoders also provide a digital number but the range is not limited by the number of revolutions.

The 62A01-01-020S is an incremental encoder that utilizes a pulse-on-notch scheme. It is an optical rotary encoder that produces a series of pulses as the input shaft rotates. The encoder has a resolution of 20 pulses per revolution, a mechanical angle of 360 degrees, and a maximum rotational speed of 300 RPM. It is specifically designed for use in industrial or homing applications, such as in robotic arms or manipulators.

Incremental encoders like the 62A01-01-020S are used in a variety of applications, including motor control, automation, servo feedback, and position control. The encoder’s output is fed to the drive electronics or controller, which can then use the feedback to maintain the pre-programmed position or speed.

The working principle of the incremental encoder is fairly simple. As the shaft rotates, light from an LED is projected onto a photodetector at a certain angle. As the shaft rotates, the LED beam passes through a gap in the sensor disc, which breaks up the beam of light into pulses. These pulses are then received by the photodetector and are processed by the controller, giving an accurate representation of the shaft’s position.

The 62A01-01-020S is an ideal solution for a variety of industrial applications. It is highly accurate, reliable, and cost-effective encoder that provides high accuracy and long-term reliability. The 62A01-01-020S encoder is a great choice for applications where precise and accurate positioning is required at a reasonable cost.
