Belimo LMB24-SR Damper Actuator

The Belimo LMB24-SR Damper Actuator delivers precise modulating control for HVAC systems. This direct-coupled, non-spring-return actuator operates on 24 V AC/DC to position dampers with smooth, accurate motion.

Key specs include a 45 in-lb torque and 95° rotation, housed in a rugged IP54/NEMA 2 enclosure for reliability in challenging environments. Its compact size (2.6"W x 2.34"D x 6.57"H) and a 1/4" to 5/8" shaft diameter fit a wide range of dampers, while the included anti-rotation strap helps ensure secure installation. A 3 ft 18 AWG plenum cable with a 1/2" conduit connector simplifies wiring for HVAC installations.
