age and washdown environments, where corrosion resistance, compact size, and flexible motor sizing are important features. The reverse-parallel motor mount reduces the length of the actuator to fit in tighter spaces, and belt reduction options offer flexibility in sizing the motor. The addition of a rear clevis pivot mount provides greater mounting versatility. The ERD is an economical rod-style electric actuator series designed as an alternative to pneumatic cylinders and an option for automating manual processes. The stainless-steel construction options are suitable for a wide variety of food and beverage applications, including volumetric filling, slicing, cutting, product changeovers, diverting/sorting, and packaging. The actuators can be built to order in stroke lengths up to 24 inches (609.6mm) and shipped in five days. The ERD electric cylinders with reverse-parallel motor mounts are available in two body sizes that are approximately equivalent to 1.5-inch (38.1mm) and 2-inch (50.8mm) bore pneumatic cylinders. The actuators are available with forces up to 500 lb (2,224 N) and speeds up to 40-inch/sec (101.6cm/sec). The ERD in the reverseparallel configuration is compatible with most NEMA and metric mount stepper and servo motors to create a flexible, powerful electric actuator solution. All ERD products are round bodied. 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 metricthreaded 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 electric cylinders 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 clampon installation anywhere along the actuator tube. All switches are CE-rated and are RoHS-compliant for environmental compatibility. LONGER LIFE TUBUS Bumpers OUTPERFORM RUBBER, URETHANE AND COILED STEEL Tolomatic Product Line Of Innovative Brushed DC Motors, Planetary Gearheads, & Encoders These high-performance precision drives are easily configured The DCX motors have precious metal or graphite brushes and may be equipped with standard preloaded ball bearings or sintered bearings and cover a large voltage range with six different ironless windings. With the new housing, almost all mechanical configurations are possible. The mounting flange can be fully configured. This includes the thread diameter, position, and number of mounting holes, as well as the dimensions of the centering collar. For use in small spaces, the DCX motor is also available in a short configuration without a flange. The length and diameter of the output shaft can be selected, with or without flat. The DCX motors can also be ordered with cables or with terminals. Cables are available in various lengths and with connectors. New gearheads and encoders have also been developed for the DCX motors. The GPX22 gearhead consists of individually configurable gear stages and is now even quieter and even more robust than equivalent sized gearheads. With a laser weld, the gearhead interface is joined seamlessly to the DCX motor. The GPX gearheads also come with a configurable flange. The output shaft is available in different lengths, with or without a flat, and even with cross holes or a key.
