The HKT56 series are high performance two and three channel optical incremental encoders. These encoders emphasize high reliability, high resolution, and easy assembly. Each encoder contains a lensed LED source (emitter), an integrated circuit with detectors and output circuitry, and a code-wheel which rotates between the emitter and detector integrated circuit. This index is an active high pulse that occurs once every full rotation of the code-wheel. Resolutions up to 2048 counts per Revolution are available in the two and three channel versions.
Features:
Two or three channel quadrature output with optional index pulse, TTL compatible single Ended outputs on HKT56 series, 100°C operating temperature, Easy assembly, No signal adjustment necessary, Resolutions up to 2048 counts per revolution, Maximum shaft diameter of 20mm.
Applications:
The HKT56 series provide motion detection to a very high resolution and accept a variety of shaft sizes up to a maximum of 20 mm
