Mini Cylinder

Intelligent Actuator – IAI America (Torrance, CA) offers the RCD Mini Cylinder that is designed to replace compact air cylinders used for short-stroke travel, pressing, and hoisting. It features a crosssection of 12 mm, with a body length as short as 60 mm. The cylinder incorporates a brushless DC motor, and provides maximum acceleration/ deceleration of 1G and maximum speed of 300 mm/s. It achieves 3-point positioning and push-motion operation is possible. Setting the appropriate acceleration/ deceleration rate enables the cylinder to push out a workpiece without impact. The capability for position adjustment based on a numeric value enables the cylinder to achieve precise film tension adjustment. The cylinder can be used to position a workpiece by pushing it from both sides.

Motion Controllers

ADLINK Technology (San Jose, CA) has released the PCI- 8254/PCI-8258 motion controllers that provide servo updates up to 20 KHz through hardware-based PID-FF control loop and secondorder filters, time-deterministic trajectory and velocity planning, comprehensive application functions, and diagnostic and control utilities. The program download function can execute up to eight individual tasks simultaneously, providing control performance in real time, and conserving CPU resources. The controllers also provide multidimensional interpolation, as in 3D linear/circular/spiral interpolation, for contouring applications in manufacturing industries such as laser engraving/cutting, glue dispensing, and others.
