Optical Encoders,
Modular,
30 mm, without Z phase.
The HKT30-A01 series are high performance, low cost, two and three channel optical incremental encoders. These encoders emphasize high reliability, high resolution, and easy assembly. Each encoders contains a LED source (emitter), an integrated circuit with detectors and circuitry, and a code-wheel which rotates between the emitter and detector integrated circuit. These encoders may be quickly and easily mounted to a motor. The quadrature signals and the index pulse are accessed through four 0.025 inch square pins located on 0.1 inch centers.
Features:
Small size, low cost, -40°C to 100°C operating temperature, easy assembly, no signal adjustment necessary, resolutions up to 1024 counts per revolution, TTL compatible.
Applications:
The HKT30-A01 series provide motion detection at a low cost, making them ideal for high volume applications. Typical applications include printers, plotters, tape drives, positioning tables, and automatic handlers.
