Panel Mount Optical Encoders Technical Data HEDS-5700 Series Features Description • Two Channel Quadrature Output with Optional Index Pulse • Available with or without Static Drag for Manual or Mechanized Operation • High Resolution – Up to 512 CPR • Long Rotational Life, >1 Million Revolutions • -20 to 85°C Operating Temperature Range • TTL Quadrature Output • Single 5 V Supply • Available with Color Coded Leads The HEDS-5700 series is a family of low cost, high performance, optical incremental encoders with mounted shafts and bushings. The HEDS-5700 is available with tactile feedback for hand operated panel mount applications, or with a free spinning shaft for applications requiring a pre-assembled encoder for position sensing. The encoder contains a collimated LED light source and special detector circuit which allows for high resolution, excellent encoding performance, long rotational life, and increased reliability. The unit outputs two digital waveforms which are 90 degrees out of phase to provide position and direction information. The HEDS-5740 Series provides a third Index Channel.

COLOR WHITE BROWN RED BLACK BLUE (THREE CHANNEL) OUTPUT A B V CC GND I 2 The HEDS-5700 is quickly and easily mounted to a front panel using the threaded bushing, or it can be directly coupled to a motor shaft (or gear train) for position sensing applications. information from a manually operated knob. Typical front panel applications include instruments, CAD/CAM systems, and audio/video control boards. The HEDS-5700 without static drag (free spinning) is best suited for low speed, mechanized operations. Typical applications are copiers, X-Y tables, and assembly line equipment. Applications The HEDS-5700 with the static drag option is best suited for applications requiring digital Note: Agilent Technologies encoders are not recommended for use in safety critical applications. Eg. ABS braking systems, power steering, life support systems and critical care medical equipment. Please contact sales representative if more clarification is needed.
