CE Optical Angle Encoder Sealed Absolute Angle Encoders AD-60MA-C28 RoHS

Angle encoder usually refers to an encoder with an accuracy within ±5''~10'' and a line count higher than 5000. Angle encoders are used for high-precision angle measurement where accuracy is required to be within a few seconds.
The main application scope of the enclosed angle encoder: CNC turntable; C-axis of lathe; gear measuring machine; high-precision industrial robot joints; astronomical telescopes, etc.

Advantages

As an angle measuring and inspecting device, the angle encoder is assembled with high-precision bearings and high-precision components, and can achieve a precision within arc-seconds after repeated commissioning and testing of the scanning unit. Therefore, the angle encoders have become the high-precision positioning device for rotary table, gear measuring machine, printing device, telescope, etc.

Principle of priority in installation

1. In order to ensure the measurement accuracy, make sure that the encoder spindle is concentric with the rotation center of the rotary table or instrument to the greatest extent.
2. The installation of encoder should not hinder the operation of the machine tool or instrument, and not reduce the original functions of the machine tool or instrument.
3. The encoder should not be liable to be impacted after installation. For instance, it is not liable to be impacted by the machine tool handle, braking device or other projecting section during processing and is not easy to be touched when accessing work piece.

Advantages of enclosed incremental linear encoders

The sealed incremental linear encoder measures the position of the linear axis without additional mechanical transmission. All feed mechanisms are included in the position control loop through the linear encoder, and the mechanical motion error of the control loop is detected by the signal acquisition and processing system. The linear encoder reads the head and corrects it from the control, potentially eliminating several sources of error:

1. Positioning error caused by thermal expansion of the ball screw
2. Game bug
3. Motion error caused by ball screw pitch error

Therefore, the enclosed incremental linear encoder is an indispensable basic technical resource for high-precision, high-speed processing machinery.
