The signal output includes sine wave (current or voltage), square wave (TTL, HTL), open collector (PNP, NPN), and various forms of push-pull. Among them, TTL is a long line differential drive (symmetrical A, A -; B, B -; Z, Z -), and HTL is also known as push-pull or push-pull output. The signal receiving equipment interface of the encoder should correspond to the encoder.
Signal connection – The pulse signal of the encoder is generally connected to the counter, SST-PFB3-VME SST-PFB3-VME-2-E PB3-VME-2-E , and computer. The modules connected to the PLC and computer can be divided into low-speed modules and high-speed modules, with varying switching frequencies.
For single-phase connection, used for one-way counting and one-way speed measurement.

A. B two-phase connection, used for forward and reverse counting, judgment of forward and reverse directions, and speed measurement.
A. B, Z three-phase connection, used for position measurement with reference position correction.

A. A -, B -, B -, Z – connections, due to the presence of symmetrical negative signals, the contribution of current to the electromagnetic field of the cable is 0, with minimal attenuation and the best anti-interference ability. They can transmit over long distances.
For TTL encoders with symmetrical negative signal output, the signal transmission distance can reach 150 meters.
For HTL encoders with symmetrical negative signal output, the signal transmission distance can reach 300 meters.
