600 Series Optical Encoders DESCRIPTION The 600 Series Optical Encoders are manually operated, rotary devices that output two square waves: Channel A leads Channel B by 90 electrically in a counterclockwise direction at a rate of 128 pulses per channel per revolution. The output is TTL (Transistor to Transistor Logic) compatible. PC terminals, cable and cable with connector are available. FEATURES AND BENEFITS POTENTIAL APPLICATIONS Contactless technology, with a minimum of 10 million shaft Industrial: rotations, provides long life in the application Motion sensing and control Voltage output eliminates need for A/D converters, Motor control providing a more cost-effective solution Flow control Stainless steel shafts and nickel-plated brass bushings Robotics Wide operating temperature range of -40 C to 65 C Computer peripherals -40 F to 149 F Welding equipment TTL-compatible outputs provide application flexibility Choice of terminations provides mounting flexibility Medical: Portable diagnostic equipment (EKG, ultrasound) Home health care respiratory equipment Surgical equipment Precision joysticks 600 Series Table 1.
