SMC Corporation NCDRA1BS50-90C Rotary Actuator

SMC NCDRA1BS50-90C Rotary Actuator is a 50 mm, rack-and-pinion rotary actuator from the NCDRA1 family, delivering a precise 90° swing in a compact footprint. This device converts linear motion into defined angular movement to enable reliable indexing and valve actuation in tight automation spaces, making it well suited for compact machinery, assembly lines, and transfer applications where space is at a premium. Some variants of the NCDRA1BS50-90C offer built-in sensing or magnetic feedback for position indication, allowing straightforward integration with control systems without requiring additional sensors. With its compact size and rack-and-pinion drive, the actuator provides repeatable, robust rotation in constrained installations, and aligns with standard mounting patterns for easy integration with other SMC components.
