Angle Sensors

Novotechnik U.S. (Southborough, MA) introduced the RSX-7900 Series angle sensors that provide up to IP69K ingress protection and ISO13849 PL-d safety compliance in a non-contacting design. The sensors are available in six standard measuring ranges with angles from 0 to 60, to 0 to 360 degrees with unrestricted rotation. Resolution is 12-bits across a 4 to 20 mA output, with linearity to ±1% at ≥ 90 degrees. Repeatability is 0.2°, and update rate is 5 kHz. Single and dual redundant versions are available. The sensors offer anodized aluminum housing with a stainless steel shaft for corrosion protection with salt and spray resistance. Axial and radial shaft loading is up to 300 N via a double-row angular ball bearing design. The 70-mm-diameter sensor has a nominal length of 35 mm, and is available with a choice of shaft styles.

Hexapod

Aerotech (Pittsburgh, PA) offers the HEX500-350HL high-load, six-degree-of-freedom hexapod for applications in sensor testing and high-force device manipulation. It is actuated with six struts that are built with preloaded bearings, ball screws, and drive components, and is driven by AC brushless, slotless servomotors that are directly coupled to the actuator ball-screw for drive stiffness and minimum incremental motion of 20 nm in XYZ and 0.2 μrad for θxθyθz. The platform and base can be modified with user-specific features or mounting patterns.

Level Indicator

The Model BM-T tilt Switch from BinMaster (Lincoln, NE) is a level indicator used for point level detection of heavy materials in bins, tanks, or silos, or over a conveyor belt or open pile. It is suspended vertically over a control point using a wire rope, chain, or flexible hanger. As the material level rises, the switch tips and causes a steel ball within the unit to shift position. When tilted to 15°, it activates a microswitch and causes an alarm condition. A stainless steel paddle is attached to the stainless steel shaft when the switch is used in rock, aggregates, or other heavy solid materials. A plastic sphere is suitable for lighter powders and solids. For Free Info Visit http://info.hotims.com/61062-305

Machine Controller

Mitsubishi Electric Automation (Vernon Hills, IL) introduced the iQ-R Series machine control system that incorporates sequence, motion, safety, process, and C language control into one platform. The control platform is designed for applications requiring integrated motion and safety control, tight synchronization between various processes, and high production throughput. The integrated design allows machines or production lines to consolidate control in one rack. The system can have up to 4 CPUs per rack for various combinations of motion, sequence, or process control.

Simplified Machine Design Approach for Optimal Servomotor Control

An often asked question from industrial machine builders or integrators is how they can effectively design or implement the conversion of a machine with servo technology to meet performance expectations. This is a specialized task filled with layers of complexity that can prove difficult to execute, even when the scope of work is fully understood.

Anti-Creep Mechanism Enables Ultra-Precise Motor Table Positioning

Motion control is essential for the digitization and automation of high-tech equipment, but bearings remain basic to frictionless movement. Bearing Engineers, a bearing distributor, recently changed its name to Motion Solutions (Aliso Viejo, CA) to better reflect their evolution into a custom designer of motion solutions for high-tech electromechanical systems. Developing custom solutions has lead to developing lines of proprietary products that the company manufactures in-house.
