SR & SX Deep Base Nema 4

SR & SX Deep Base Nema 4

The SR & SX series deep base rotary electric actuator was designed exclusively for applications within the 200 lb·in (model SR) and 300 lb·in (model SX) torque range with special control requirements. This heavy-duty reversing actuator is used in place of model SD and SDX when optional equipment such as 4-20mA control, timers and speed control are required. These compact actuators are equipped with spur gear drive and, as in all ICI actuators, can withstand stall conditions without suffering gear failure. The heavy-duty sand-cast aluminum enclosure meets NEMA 4 specifications and has a thermally bonded ultraviolet resistant polyester powder coating that not only enhances its appearance but also is a tough corrosion resistant coating.

Standard equipment includes 115Vac-1ph motor with thermal overload protection, two limit switches wired for light indication, stainless steel fasteners, 300 series stainless steel output drive and spring friction brake. Manual override and position indicator are not available on the S series deep base because the optional equipment used when this enclosure is specified prohibits their installation.
