Encoder module——PD22 series


Encoder module——PD22 series


Matrix reading, with high impact resistance, strength capability to error correction high reliability, and installation sizes small, wide range of resolution, do not require the signal conditioning. Assembly requirements are less, and has compensation ability of motor shaft radial and axial shifting, widely used in the DC motor, with a multi-aperture for selection.

Note: The red defined as 0V.

Out of frequency output, can use for single-chip timer / counter capture pulse,

If encoder 20 pluses raster, per revolution 20 pulses.

Computation speed: If 1 second to give 40 pulse, the speed is 40/2 = 20 rev / sec, the tire direct D, it can be calculated from the actual speed of π D * 2 / sec
