The 847 encoders are incremental optical encoders manufactured by Allen-Bradley. The 847 encoders feature metal code disks and robust mechanical designs that allow them to withstand significant levels of shock and vibration and extreme temperatures. These encoders can operate at -30 to 80 degrees Celsius or -22 to 176 degrees Fahrenheit. Additionally, they can be stored at temperatures between -40 and 100 degrees Celsius or -40 and 212 degrees Fahrenheit. The code format for the 847 incremental optical encoders is an incremental 2-channel format with zero index. The 847 encoders can simplify complex applications.
The Allen-Bradley 847 incremental optical encoders are available in six distinct models and with compact housing sizes of 2 inches or 2.5 inches. The mounting options for the 847 encoders are the square flange, servo flange, hollow shaft, and blind hollow shaft mounting options, making it easy to integrate the encoders into different machine systems. These encoders fit seamlessly into systems with limited installation space while maintaining high performance. The 847 encoders operate with DC power supplies. They support power supply voltage ratings of 4.5 to 5.5V DC or 8 to 30V DC.
The 847 incremental encoders support integer resolutions ranging from 1 to 65,536 counts per revolution. These advanced resolution ratings support a variety of precision applications, including packaging systems, cutting machines, and print and web conversion applications. Additionally, the 847 encoders are backward compatible with Allen-Bradley 844A, 844B, and 845 series incremental encoders. This backward compatibility makes it easy to upgrade existing systems and minimizes system disruptions. The 847 encoders also support multiple connection options, including M12, Military Style (MS), and flying-lead connection options to provide flexibility and allow the controllers to be used in various control systems. Some 847 encoders have axial connector/cable exits, while others have radial connector/cable exits. The 847 encoders can support line driver or open collector outputs with voltage ratings of 4.5 to 5.5V DC or 8 to 30V DC.
