Features

• High strength ground and plated extension rod
• Front end cap with bearing support, rod wiper and grease seal
• Four tie-rod construction with guided drive nut
• Thrust limit disc springs and spring limit sleeve to prevent total spring deflection
• Anti-friction bearings
• High strength alloy steel cut gears
• Gear driven potentiometer or encoder drives
• Heavy duty motor, TENV, NEMA D design, high starting torque, low inertia motor provides high breakaway forces and good positioning characteristics. Class F insulation is standard.
• Versatile mounting, clevis (7100 only) trunnion or face/flange
• Adjustable position limit switch. A two position gear-driven position limit switch for end-of-travel actuator shutoff and a set of contacts for light indication are included as standard. Each position is independently adjustable and can be set anywhere within the full actuator travel. The heavy-duty rotary drum, double break switch with wiping contacts feature a patented mechanism that ensures internal gear engagement after adjustment.
• Adjustable thrust limit switches. An adjustable thrust switch for each direction of travel is provided as standard. The switch assembly will automatically shut off the actuator if the set force is exceeded. The switch protects driven equipment from damage due to excessive forces and can also be used as a mechanism for positive seating.
