Belimo NMX24-3-T-N4 Non-Spring Return Rotary Actuator Overview
The Belimo NMX24-3-T-N4 is a heavy-duty non-spring return rotary damper actuator engineered for dependable performance in commercial and industrial HVAC applications. Delivering 10 Nm (90 in-lb) of torque at 24V AC/DC, this actuator is well-suited for medium to large damper assemblies where precise, reliable positioning is essential. The 3-position (floating) control signal allows for straightforward integration with building automation systems, while the terminal strip (T) wiring connection simplifies field installation and commissioning.
