ORDERING INSTRUCTIONS

The BME Series are high performance, low cost, 2 or 3 channel optical incremental encoders. Each encoder contains a

LED source, an integrated circuit with detectors and circuitry, and an optical disc which rotates between the emitter and

detector IC. These encoders can be quickly and easily mounted to a motor.
