NPN outer diameter 18mm mini rotary encoder solid shaft 2.5mm 60ppr
3.3Vdc
1,Working principle:
By a central shaft of the photoelectric code disk, which has a ring
through, dark inscription, there are photoelectric transmitting and
receiving devices read, to obtain four groups of sine wave signals
combined into A, B, C, D, each sine wave difference of 90 degrees
phase difference (relative to a circumferential wave for 360
degrees), the C, D signal reverse, superimposed on the A, B two
phases, can enhance the stability of the signal; the other each
turn output a Z-phase pulse to represent the zero position
reference position.
Since the phase difference between A and B is 90 degrees, it is
possible to distinguish the forward and reverse rotation of the
encoder by comparing whether phase A is in front or phase B is in
front, and the zero reference position of the encoder can be
obtained by the zero pulse.
