600 Series Optical Encoders
The 600 Series Optical Encoders use non-contact technology to convert mechanical rotary motion into a digital electrical
output. This output, compatible with transistor-transistor logic (TTL), may eliminate the need for analog to digital converters.
These encoders are rotary devices which contain a rotor and stator pair that create a variable aperture to allow light from
a light emitting diode (LED) to pass through to a photosensitive diode. The rotor represents the number of lines (pulses) of
the encoder and the stator creates the positioning of the individual outputs, or phasing. The varying amount of light allowed
through the aperture creates a sine wave output. Internal electronics then amplify and convert this sine wave output into a
square wave.
Two square waves, Channel A and Channel B, provide a quadrature output. Channel A leads Channel B by 90º electrically
in a counterclockwise direction at a rate of 128 pulses per channel per revolution. Quadrature output allows the user to
potentially determine incremental position, direction and speed.
The 600 Series is available with PC terminals, cable, or cable with connector.
