Tolomatic (Hamel, MN) offers ERD electric cylinders in six body sizes. The ERD is a rod-style electric actuator family designed as an alternative to pneumatic cylinders, and an option for automating manual processes. They are suitable for motion control applications such as washdown environments, product changeovers, diverting/sorting, pressing, and heat-staking/sonic welding. The cylinders are available in stroke lengths up to 40 inches (1,016 mm), speeds up to 57.5 inches/sec. (1,460.5 mm/sec.), and forces up to 4,500 lbf (20.03 kN), depending on the size and screw choice. They are available with ball screws, roller screws, and acme screws for a variety of cost, force, speed, and life options.
The ERD is compatible with most third-party servo and stepper motors (NEMA and metric). The motors can be mounted inline with the actuator or in a reverse-parallel motor mount with belt reduction options. The 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. Commonly used for end-of-stroke positioning, these switches allow clamp-on installation anywhere along the actuator tube.
