Tolomatic’s ERD actuator — electric alternative to pneumatic

Tolomatic’s new ERD electric rod-style actuators are designed as an economical electric alternative to non-repairable pneumatic cylinders and provide design engineers with a new option for automating manual processes. Sleek and compact, ERD electric rod-style actuators deliver forces up to 75 pounds (334 N) at speeds up to 40 inches per second (1,016 mm/sec). ERD actuators are stroke configurable and ship within five days from order entry at the factory. The products are suitable for a wide variety of applications, including product change-overs, pick-and-place, sorting and diverting, heat-staking and more.

Tolomatic's ERD Series Electric Linear Actuators

“With the growing trend towards use of electric actuators, the new patent pending ERD electric rod-style actuator provides an alternative to pneumatic cylinders with the added benefit of greater control of speed, acceleration and force,” says Aaron Dietrich, electric products manager, Tolomatic. In addition, the ERD is a very affordable option for automating manual processes and is particularly exciting for us in that the line opens up the entry level segment of the market where we have not had catalog products available in the past.”

The ERD electric rod-style actuator is available in body sizes that are equivalent to 5/8″, 1″ and 1.5″ bore non-repairable pneumatic cylinders. These three sizes are available in stroke lengths up to 8, 10 and 12 inches, respectively, and forces up to 20, 40 and 75 pounds. The three sizes, from small to large, accept NEMA 11, 17 or 23 frame stepper and servo motors. The acme lead screw is made of high-performance steel and is available in three lead sizes per size to optimize speed or force.

“The ERD actuator comes standard with a metric-threaded rod end that makes it compatible with a wide variety of commercially available accessories,” says Dietrich. “This makes the conversion from pneumatic to electric even more convenient.”

ERD products 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. Commonly used for end-of-stroke positioning, these switches allow clamp-on installation anywhere along the actuator tube. All switches are CE rated and are RoHS compliant for environmental compatibility.

Tolomatic’s electric linear actuators are used in a variety of industries, including the packaging, material handling, medical, food processing, automotive, semiconductor and general automation industries.

Compact OEM module for brushless DC motors with Hall sensors

Innovative and revolutionary speed controller

The maxon motor DEC module 50/5 controller is a digital amplifier with speed controller for controlling brushless DC motors with Hall sensors up to 250 watts.

Maxon's DEC 50/5 Servo Amplifier

Maxon’s new module works with an operating voltage of up to 50 VDC, an output current of 5 A in continuous operation and its usage is flexible, versatile and highly efficient. The amplifier offers a large number of inputs and outputs, including enable, speed ranges, speed monitor, direction of rotation presetting, current limiting, operating status etc., and offers comprehensive protection features. This means that overcurrent, undervoltage and overvoltage, thermal overload and short circuit are integrated to ensure that the controller can be used securely.

The all-in-one amplifier with an extremely high power density of 250 watt continuous output power at 12 cm2 (3 x 4 cm) may be seamlessly integrated into complex applications with minimum effort. Maxon’s offers a comprehensive motherboard design guide for integration into OEM boards and a detailed evaluation board is made available for the initial start-up.
