LME-2000D-T2000K

rev. page 1 of 5 date 01/2009 DESCRIPTION: modular incremental encoder PART NUMBER: LME The LME Series are high performance, low cost, 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.
