Product Announcement from Indelac Controls, Inc.
Our S series NEMA 7 rotary electric actuators were designed solely for applications within hazardous locations. The torque range for these models is:
200 lb·in (22.6 Nm) - model SR7
300 lb·in (33.9 Nm) - model SX7
These heavy-duty reversing actuators are used in place of model SD4, SR4, SDX4 and SX4 when the area used in requires enclosure rating of Class I Groups C & D or Class II Groups E, F & G div. I and II. These compact actuators are equipped with spur gear drive and as in all ICI actuators can with stand stall conditions without suffering gear failure. The heavy-duty sand-cast aluminum enclosure meets NEMA 7 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
Includes 115Vac-1ph motor with thermal over load protection, two limit switches wired for light indication, stainless steel fasteners, 300 series stainless steel output drive and spring friction brake.
