The encoder selection considerations

In the process of using a rotary encoder, struggle and selection of rotary encoder, in order to solve this problem, the electronic in the process of selection of the commonly used two kinds of rotary encoder note summary description: type 1 incremental rotary encoder selection considerations, 1) Mechanical installation dimensions, including the diameter of axle, the number of the installation; Cable wire way; Installation space volume; Work environment protection grade whether meet the requirements. ( 2) Resolution, that is, each lap of the output pulse encoder work, using precision whether meet the design requirements. ( 3) Electrical interface, the encoder output way has a push-pull output (common F type HTL format) The output voltage, ( E) , open collector ( C, C for common NPN output, C2 for PNP tube output) Long-term drive output. Its means of output should match the interface circuit of the control system. 2, absolute rotary encoder selection considerations, 1) Mechanical part (1) measuring the length and Angle measurement, how length measurement by mechanical conversion ( Above are some introduction, such as unclear can call to discuss) 。 Measuring Angle is 360 degrees ( Lap) , or may have 360 degree ( More rings) 。 Production process is a direction of rotation cycle to work, or work direction cycle back and forth. (2) shaft connection installation form, type shaft through a flexible shaft coupling, or shaft sleeve type connection. (3) using the environment: dust, moisture, shock, impact? ( 2) Electrical part (1) connect the output of the receiving part (2) signal form (3) the resolution demands (4) control, in short, before use should be in all aspects of the comprehensive factors to consider to choose what kind of rotary encoder, appropriate if there is any doubt welcome to discuss with us.
