The AEGIS SGR Conductive MicroFiber Shaft Grounding Ring (SGR) from Electro Static Technology is suitable for predictive and preventive maintenance programs on VFD-controlled ac motors and large dc motors. Unlike conventional shaft grounding brushes, the SGR’s conductive micro fibres are said to work with virtually no friction or wear; are unaffected by dirt, grease, or other contaminants; and last for the life of the motor, regardless of rpm.

The Actuator Division of Parker Hannifin has introduced the LCB series of compact linear actuators. The series incorporates a low friction, dry running sliding bearing carriage said to provide long, reliable travel life - even at 100% duty cycle. Coupled with Parker motors/controls, the series of linear actuators is also said to offer a fully programmable, high-performance solution at a competitive cost, while reducing space requirements.

Magnet-Schultz of America has introduced the 44X32 solenoid. The solenoid is being offered in both the R44X32 Standard Pull Style and the RL44x32 Magnetic-Latching Pull Style.Units can accommodate up to 5 lb in the continuous duty mode, up to 10 lb in the intermittent duty mode and up to 30 lb in the pulse duty mode - all at a maximum stroke of one in.

Haydon Switch & Instrument, Inc. has announced that its size 23 hybrid linear actuators are now available with a 0.9° step angle. This step angle is designed for higher resolution and allows for a full step linear movement of 0.0000625 in. (1.6 microns). Like the 1.8° version, the actuator is available in all four designs; captive, non-captive, external linear, and linear rotary.

Danaher Motion has introduced version 1.4 of its NDC8 control platform for automated guided vehicles (AGVs). The control platform now supports up to 10 ac drives per AGV. The drives can be used for steering, driving or auxiliary control, and ac technology helps increase power while reducing running costs. An updated curve-editing tool provides the freedom to adapt each AGV layout to suit specific application needs, and new spline-based flexible curves allow for increased vehicle speed at corners, while saving floor space when negotiating tight corners.

The Exlar Tritex series of electric actuators from Exlar Corp. combine a brushless servo motor, servo amplifier and position controller to eliminate the external servo amplifier and the cables associated with a typical servo system. Tritex actuators with built-in mechanical converters replace electric drive systems employing ball screw or gear reducer mechanisms. Up to 500 W of continuous power can be applied to the actuator's brushless servo motor with strokes of 3 to 18 in. available. The standard product is rated IP54 with an optional IP65 rating available.

QuickSilver Controls, has announced it has extended its ability to 'servo' rotary microstep motors to include 'servoing' linear step motors. The QCI-L6 is a linear motor with servo control capable of acceleration moves up to 8.4 G, suitable for pick-and- place, wire bonding, semiconductor, parts inspection and other high acceleration applications. Maximum velocity is 6.4 fps.

Red Lion Controls, Inc. has announced native tag support of Allen Bradley's Logix series PLCs. Red Lion G3 series HMI, Modular Controller and Data Station products can be integrated with the ControlLogix and CompactLogix PLCs, via serial or Ethernet. The PLC's tags are exported as a CSV file from Allen Bradley's RSLogix 5000 software, and then imported into Red Lion's Crimson 2.0 software. A click of a button automatically creates matching tags within Crimson.
