Allen-Bradley / Rockwell Automation High-Freq Inc Optical Encoder 844D-B5CC2LS

The 844D-B5CC2LS is a high-frequency optical incremental encoder designed for precision applications. It features a dual-channel output with a maximum resolution of 16,384 pulses per revolution and supports output frequencies of up to 600 kHz for resolutions above 8192 PPR. The encoder operates with a power requirement of 120 mA (no load) and is compatible with various line driver outputs, including ¬±40 mA and ¬±200 mA options. Mechanically, the encoder can handle angular accelerations of up to 100,000 radians/sec¬=, with a maximum slew speed of 3000 rpm. It has a starting torque of 9.3 Ncm and a running torque of 5 Ncm at 25 ¬8C. The encoder supports shaft sizes ranging from 1/2 inch to 1-1/8 inch and 30 mm, with specific axial and radial load ratings depending on the resolution. Environmentally, the encoder is rated NEMA Type 4, 13, and IP66, making it suitable for harsh conditions. It operates within a temperature range of -20 to +85 ¬8C and can withstand humidity levels of up to 90% non-condensing. The housing is made of aluminum, ensuring durability and resistance to environmental factors. This encoder is ideal for applications requiring high precision and reliability in motion control systems.
