ERD electric cylinders from Tolomatic (Hamel, MN) are available with a reverseparallel motor mount that makes a more compact package. The motor is mounted in parallel with the actuator instead of inline, which reduces the length of the total package and, with the addition of a rear clevis pivot mount, provides greater versatility in mounting the actuator. The ERD is a rod-style electric actuator designed as an alternative to pneumatic cylinders, and as an option for automating manual processes. The products are suitable for product changeovers, pick-and-place, pressing, diverting, and heatstaking/ sonic welding. The actuators can be built in stroke lengths up to 24" (609.6 mm). The cylinders are available in four body sizes that are approximately equivalent to 5/8" (15.9 mm), 1" (25.4 mm), 1.5" (38.1 mm), and 2" (50.8 mm) bore pneumatic cylinders. They are available in stroke lengths from 8 to 24" (203.2 mm to 609.6 mm), and forces up to 500 pounds (2,224 N). They are compatible with most NEMA and metric mount stepper and servo motors.

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. These switches allow clamp-on installation anywhere along the actuator tube. All switches are CE-rated and are RoHS-compliant for environmental compatibility.
