Encoders are specialized transducers designed to provide instantaneous digital readouts of linear, rotary, or angular mechanical motion. ZNH1800H rotary encoders use modern technologies to provide accurate, durable, low cost position sensing systems. ZNH1800H provides high performance through an innovative combination of optical sensing, signal processing, and modern digital interfaces.

Application Fields

ZNH1800H is capable of measuring rotary motion over a wide range of speeds and distances. It can be used in a variety of industrial and consumer applications, including robotic systems, medical devices, and many automated processes. This encoder can also be used to measure the speed of a motor or to detect a gearbox’s output rotation. It can be used to control the speed and direction of a rotor, to measure distances traveled, or to detect the position of a rotary mechanism.

Working Principle

ZNH1800H encoder works by providing a digital output signal when a physical mechanical motion occurs. It uses a combination of optical and electrical components to sense and convert linear and rotary mechanical motion.

The optical sensing is achieved by using a series of optical discs and slots on the rotor members of the encoder. Light from an LED light source is projected onto the optical discs. As the encoder rotates, the light is blocked by the different slots in the optical discs. This produces a series of electrical output signals which are sent to a signal processing circuit. This circuit then converts the signals to digital signals, which can be used to measure position, speed, and direction.

ZNH1800H encoders also use a magnet, Hall effect sensors, and electronic signal processing circuitry to accurately measure the angle of rotation. The magnet is mounted to the rotor and the Hall effect sensors are arranged in circle around the magnet. As the magnet rotates, it produces a series of electrical pulses. These pulses are then sent to the signal processing circuitry, which calculates the angle of rotation from the pulses and then sends the digital signal to the output port.

Conclusion

ZNH1800H encoders are a popular choice for applications requiring accurate, reliable, and low cost rotary measurement. They use an innovative combination of optical sensing, signal processing, and digital interfaces to provide precise position and speed measurements. They are widely used in robotics, medical device control systems, and automation systems.
