Rotary Encoder Signal output！

Signal output

    There are a sine wave output signal (current or voltage), square wave (TTL, HTL), open collector (PNP, NPN), push-pull many forms, as long TTL differential drive (symmetric A, A-; B, B -; Z, Z -), HTL, also known as push-pull, push-pull output encoder signal receiving device interface should correspond with the encoder.
    Signal connection - module encoder pulse signal typically connected counter, PLC, computer, PLC and computer are connected to high-speed and low-speed module module of the points, with a high switching frequency is low.
    Such as single-phase connection, for uni-directional counting, one-way speed.
    A.B two coupled for forward and reverse counting, and speed to determine the pros and cons.
    A, B, Z-phase coupling for position measurement with a reference bit correction.
    A, A-, B, B-, Z, Z- connection, since the connection with symmetrical negative signals, the contribution of the current cable for the electromagnetic field is 0, the minimum attenuation, the optimum interference can transmit greater distances.
    For TTL signal output with symmetric negative encoder signal transmission distance up to 150 meters.
    Rotary encoder constituted by a precision devices, so when subject to greater shocks may damage the internal functions shall be paid to use.
