Description
Rotation sensor choices E256, E360, E500, & E512: Four optical encoder resolutions are offered, see the table below. Each of these encoder choices has 4 outputs, shown graphically below. Outputs A and B are in quadrature (exactly 90° out of phase). Output I is an index pulse. Output A+B is the exclusive OR of A and B, which doubles the basic resolution of the encoder. The outputs, 0 to 5 volt pulses, can drive TTL loads. The encoders will operate from a +5 to +20 Vdc, 100 mA power supply. Temperature range is -40F to +212F. The encoders have metal code wheels and rugged electronics so they tolerate shock and vibration. They are also protected from incorrect wiring up to 20 volts. Accuracy of encoder systems is 0.25° (maximum cumulative error).
