- Used condition—fully functional and cost-effective alternative to new units
Technical Specifications
The 845K series encoders are designed for rotational feedback in motion control circuits. Specific electrical parameters, output counts per turn (CPT), and connector configuration depend on the full model designation. For exact voltage, current, and signal specifications, consult the encoder’s datasheet or contact a Rockwell Automation distributor with the complete part number and serial information.
Typical Applications
- Rotational position feedback for servo and stepper motor systems
- Speed monitoring in conveyor and belt-drive equipment
- Precision positioning in assembly and packaging machinery
- Legacy system maintenance and upgrades
- Replacement units for existing Allen-Bradley encoder installations
Compatibility & Replacements
Allen-Bradley 845K encoders are compatible with Rockwell Automation control systems, including CompactLogix, ControlLogix, and MicroLogix PLCs equipped with appropriate analog or digital input modules. Connector type and signal format are determined by the model suffix (CMY3 designates the specific connector and signal configuration). For interchangeability with other encoder families or exact compatibility verification, consult Rockwell Automation technical documentation or your authorized distributor. This unit is supplied in used condition and is verified as functional.
