HEDS-5500#H12 [Broadcom]

The HEDS and HEDM series are optical incremental encoders with two or three channels. They feature a lensed LED source, integrated circuit with detectors and output circuitry, and a codewheel that rotates between emitter and detector. HEDS uses metal codewheels, while HEDM uses film codewheel allowing resolutions up to 1024 counts per revolution. Key advantages include quick and easy assembly, no signal adjustment required, TTL compatibility, single 5V supply, and small size with operating temperature range for HEDS series.
