Encoders are an integral part of various common machineries, thanks to their capability of converting an input signal into something that can be used by machines. The 60AD18-4-H-P encoder is a common type of encoder used in industrial settings, and is used to provide precise feedback information. This article explores the application field and working principle of the 60AD18-4-H-P encoder.

Application Field

The 60AD18-4-H-P encoder is primarily used in the control systems of various industries. It is deployed in a range of industrial processes such as tracking the motion of a motor or as a feedback device in CNC machines. This type of encoder is also used to detect the position of metal and plastic forms in the fabrication industries. The 60AD18-4-H-P model is applicable in several situations where remote or wireless monitoring is required, as it can transmit the required data back to a base station.

Working Principle

The working principle of an encoder is based on a disc assembly, which includes an occluded disc made up of a series of "windows" or "slots" along its circumference. The abscissa and ordinate axes (XY) of the disc are covered by the same material as the occluded disc to form a single piece. This creates an assembly that rotates with the occluded disc when its shaft is driven. As the disk rotates, the windows along its circumference interleave with the illumination source like a shuttered wheel would do.

The windows in the occluded disc are part of an optical sensor, and when they pass in front of the emitting source of illumination, they are detected by the sensor. When the illumination is interrupted by the windows, a signal is sent to the examining circuit. This signal is then processed by the encoder, providing positional information of the disc to the examining circuit.

To obtain the absolute position of the occluded disc, the precision "windows" are coded to produce a binary number. Depending on the resolution needed, the size and number of windows are adjusted, and an angular resolution is determined. Furthermore, to keep the encoder reliable, a compensation mechanism is built into the disc assembly. This includes a shimming mechanism which compensates for radial misalignment, and a center index window which compensates for angular misalignment.

In conclusion, the 60AD18-4-H-P encoder is a useful industrial component, applicable in many modern industrial systems. Its working principle is based on the discrete detection of light passing through a series of precision windows, providing precise feedback systems for motors or CNC machines. This encoder is also a viable solution when wireless monitoring is required.
