The Delta NH4-17LS65CAM is a high-precision incremental rotary encoder designed for demanding motion control and industrial automation applications. Manufactured by Delta Electronics, this encoder features a hollow shaft design for easy and direct mounting onto motor shafts, saving space and reducing coupling errors. With a resolution of 2500 pulses per revolution (PPR) and a robust line driver output, it delivers reliable and accurate feedback for precise positioning, speed control, and measurement tasks. Its open-frame construction with an exposed PCB is common for integration into servo motors and other compact systems, providing essential feedback in a lightweight package.
