Enhancements to Posital’s programmable encoders have made it simpler to configure wheel-equipped encoders to meet user requirements. Wheel-encoder assemblies measure speed and position directly from a moving surface, avoiding errors due to gear backlash or hysteresis. Posital’s measuring wheel- encoder combinations provide resolutions as fine as 0.1 mm/pulse for all available wheel sizes. The IXARC incremental encoders—the heart of the wheel/encoder set—are programmable. Commonly used resolutions, such as 1000, 1024 or 2048 PPR are available, along with resolutions as high as 16,384 PPR. Likewise, output drivers can be set to either push-pull or RS422 to ensure compatibility with PLCs. If production machinery is modified later, wheel/encoder sets can be re-configured through software updates.
