What is an enclosed air engaged torque limiter and why choose the Nexen TL-A-E series for industrial drives? This line of air-powered torque limiters delivers precise slip-torque protection in a compact, set-screw mounted housing with a 360° engagement. The TL-A-E family features a 1.000 in (25.4 mm) bore, NSB construction, and IP54 protection for wet or dusty environments, plus a nickel-plated exterior for corrosion resistance. Remote torque adjustment is available via single or double air pressure circuits, and a proximity sensor with a 3 ft cord is included on all models for easy automation integration. Specs span small to high torque variants, with Max static clutch torque up to 2150 in-lbs (243 Nm) and torque capabilities up to 10,820 in-lbs (1224 Nm) at 80 psi, making it ideal for precise overload protection in conveyors, packaging lines, and machine tools.
