Low-Profile Rotary Stages

Direct-drive, feature automated material handling

The ACS LP series ultralow profile rotary stage with integrated ER collet chuck provides automated material handling capability for a wide range of materials and applications. ER collets provide excellent run-out characteristics for applications requiring high-precision gripping of tubular material, and are readily available in sizes that support tube diameters from 0.5 mm to 16 mm. The collet is retained with a threaded retaining cap that enables quick changeover, and is configured in a "fail-safe" normally closed mode where full clamping force is applied when no air pressure is present. Air is delivered to the collet or gripper assembly through an integral rotary union using a seal-less, frictionless design. This 100 percent noncontact rotary-union design ensures a lifetime of maintenance-free operation. The combination collet chuck and rotary union assembly also has significantly less friction and inertia than external assemblies created from discrete parts. This reduced inertia improves system performance by allowing higher peak acceleration and reducing position error during laser machining operations. Aerotech Inc.http://rbi.ims.ca/4412-625

Interactive Website

Takes the guesswork out of specifying precision linear actuators

Specifiers of precision linear actuators will benefit from the new interactive website launched by Ultra Motion. By going online to www.ultramotion.com and selecting a motor and lead screw for the "Digit" series of linear actuators, or motor, lead screw, and belt-drive-ratio (1:1, 2:1, 3:1, 4:1, and 5:1) for the "Bug" series, a Force/Speed Curve is generated. Being able to configure an actuator and evaluate it's a performance online saves time and takes the guesswork out of specifying an actuator to meet the requirements of an application.

Poppet Valves

Latching solenoid

The 315L/415L Series latching poppet valves have a single direct-acting solenoid that is designed for reliable operation. A momentary electrical signal changes the valve's position. Then the magnetic latching mechanism maintains that position until another signal returns the valve to the original position. This ensures continuous operation in a particular mode, even in the event of a facility power failure. The latching feature on the 315L/415L Series valves enables designers to replace a double-coil or double-solenoid valve, saving space. It also eliminates the need for an external air supply or continuous current to maintain position, saving money. The poppet design needs no lubrication and can perform under adverse conditions. And the high 0.42 Cv flow rate in a compact size reduces the overall footprint of the design. The 315L/415L Series valves have a pressure range from vacuum to 125 psig. The three-way and four-way porting configurations offer design flexibility. They are available with 0.125-inch NPSF ports for in-line mounting, and for use on Humphrey's range of standard and custom manifolds. Humphrey Products Co.http://rbi.ims.ca/4412-631

AEGIS Products

Protect ac motor bearings

When variable frequency drives are used to control ac motors, currents are induced on the motor shaft. These harmful currents build up until they are strong enough to discharge through the bearings, causing fusion craters (frosting, pitting, fluting, etc.) that lead to premature motor failure. By channeling such currents to ground with their patent-pending Electron Transport Technology, AEGIS products from Electro Static Technology prevent such damage and dramatically extend motor life. Designed for a variety of applications, these products are fit for OEM motor manufacturers and motor repair shops as well as in-house maintenance. Three different products provide rugged, reliable protection for any size motor. Easily installed and maintenance-free, they last for the life of the motor.
