– Compatibility & Integration
The AR-23-2-2-F-1-X integrates directly with Parker/Compumotor AX-A micro-stepping indexer/drive systems (1024 positions/rev configuration). The associated decoder box supports multiple communication standards, enabling flexible integration into control architectures ranging from legacy BCD systems to modern RS-422/485 networks. Multiple encoder heads can be daisy-chained via RS-422/485 for distributed position sensing in multi-axis applications.
