The 700 and 800 series encoders from Leine & Linde, the HC-HTL outputs can drive a 0-30V square-wave signal with frequency of 100kHz. Signal quality exceeds industry standards for voltage amplitude and signal rise-time while driving as much as 350 meters (~1150 ft) of cable when terminated into a 40 mA resistive load. Signal integrity is maintained with temperatures ranging from -40 to 85 °C.
The length of cable an encoder is capable of driving depends upon many factors. The cable type, mechanical properties, and overall length determine the capacitance and resistance the encoder output drive electronics must handle. This type of load will ultimately limit the amplitude and frequency of a signal transmitted. Lower frequencies would allow for even longer cables.
