Tolomatic ERD electric rod-style actuators are designed as an electric alternative to pneumatic cylinders. They can deliver forces up to 334 N at speeds up to 1016 mm/s. ERD actuators are stroke configurable and are suitable for a wide variety of applications, including product changeovers, pick-and-place, sorting and diverting, and heat-staking.
The ERD electric rod-style actuator is available in body sizes that are equivalent to 1.6, 2.5 and 3.8 cm bore non-repairable pneumatic cylinders. These three sizes are available in stroke lengths up to 20.3, 25.4 and 30.5 cm respectively, and forces up to 89, 178 and 334 N. The three sizes, from small to large, accept NEMA 11, 17 or 23 frame stepper and servo motors.
ERD actuators are round bodied, following the footprint of most pneumatic actuators in this performance class. The rear head of the actuator features an oversized main bearing to accommodate high thrust loads and provide long life. The main tube and thrust tube are made of stainless steel for high rigidity and corrosion resistance, while the metric-threaded nose mount accepts a jam nut that provides convenient mounting for many applications. Mounting options include a rear trunnion mount, foot mounts or a front flange mount.
The ERD actuators can accommodate six different sensing or switching choices: reed, solid-state PNP (sourcing) or solid-state NPN (sinking), normally open, flying leads or quick-disconnect. The switches are activated by a standard internal magnet located inside the thrust tube.
