EN12-HN22AF20

Encoders are devices which are widely used in generating digital signals for computer controllers or other automation equipment. They are based on the principles of encoding physical motions such as rotation of a shaft or linear/angular displacement into digital or analog signals which are accepted by computer controllers.

The EN12-HN22AF20 is a common type of encoder. It is a two-channel, quadrature digital rotary encoder. Quadrature encoders measure the direction and speed of a rotating shaft in one single structure. It is characterized by its small size, robust construction, low power consumption, high resolution, long life, good linearity & repeatability, and an excellent price to performance ratio.

The working principle of the EN12-HN22AF20 revolves around two optical sensors, also known as "tachogenerators". These devices capture the motion of the rotary encoder shaft by emitting light on a code wheel. As the code wheel rotates, it generates two identical non-slip quadrature output signals that are 90 degrees out of phase. These signals are then used to measure rotations in a clockwise or counterclockwise direction.

The EN12-HN22AF20 is used in a wide variety of applications, such as industrial automation, robotics, automotive, and medical systems. It can be used to measure angular velocity, linear velocity, acceleration, and position. It is also used to control DC or stepping motors, read/write data to a computer, and measure angles in robots or other motion control systems. Its high resolution and low power consumption make it ideal for applications where accurate measurements and low power consumption are required.

In summary, the EN12-HN22AF20 is a type of quadrature digital rotary encoder which is widely used in industrial, automotive, and medical systems. Its working principle is based on two optical sensors and it is characterized by its small size, robust construction, low power consumption, high resolution, long life, good linearity & repeatability, and an excellent price to performance ratio. Although it is used in a wide variety of applications, its most common usages include measuring angular velocity, linear velocity, acceleration, and position, as well as controlling DC or stepping motors, reading/writing data to a computer, and measuring angles in robots or other motion control systems.
