Potentiometer

Hoffmann + Krippner (Woodstock, GA) introduced the DL30 series linear motion potentiometer (transducer) series that features low-profile dimensions of 30 × 30 mm and variable lengths. Various types of resistors (e.g. wire, conductive plastic, and Sensofoil® membrane) are available. Features include compact design, rugged aluminum housing, and output options of 0/4mA, 20mA, or 0V-10V. They are available in lengths of 30 mm to a maximum of 500 mm. Resistor options are wire wound, conductive plastic, or an incorporated Sensofoil® membrane potentiometer. For Free Info Visit http://info.hotims.com/55590-315

Track System

Accuride (Santa Fe Springs, CA) introduced the Model AL4190 Tilt Track System that provides access to drawers or trays installed at shoulder level and above. The system uses wheels and rollers to extend the drawer, and an aluminum channel guides the back of the drawer upward as it slides out of the case, tilting the drawer downward for easy viewing and access to contents. The system carries drawers up to 40" wide and loads up to 140 pounds. The system is comprised of lightweight, corrosion- resistant aluminum tracks, roller wheel assemblies, and track rollers. Tracks are available in lengths of 24" and 40". The system is fully adjustable with the drawer in place. The installer can alter the angle of the tilt, which varies based on the angle of the track, attachment location of the track roller, and positioning of bumper stops.

Actuators

Nook Industries (Cleveland, OH) offers Series 500™ programmable actuators designed for continuous duty and long service life. They incorporate a direct or toothed-belt drive for high mechanical efficiency. Ball screw-driven programmable actuators are made with high-strength materials, and are available in parallel and in-line models with either a servomotor or stepper motor. The screw shaft is constructed with medium-carbon, induction-hardened alloy steel, and the ball nuts are manufactured from high-grade bearing steel. Both ball screw and nut are heat-treated to a surface hardness of 56 HRC.

Machine Control

Unitronics (Quincy, MA) has introduced Samba, a palm-sized PLC with HMI and onboard I/Os for machine control that features a color 7" HMI panel. The 16-bit touchscreen enables data entry and display of variable data, including color trend graphs and alarm screens. Samba supports 24 userdesigned screens and 5-MB images per application. The integrated PLC offers features including two auto-tuned PID loops, time-based RTC control, data logging, and recipes. The internal memory holds 112 KB of application logic, plus 512K for fonts and 5 MB for images. Onboard I/Os offer digital, analog, and high-speed functionality.

Accelerometer Chips

Silicon Designs (Kirkland, WA) offers industrial-grade MEMS variable capacitive accelerometer chips and modules for zero- to medium-frequency instrumentation applications. Onboard voltage regulation and an internal reference minimize temperature and voltage changes while eliminating additional external power regulation requirements. Each sensor is made to be virtually identical, allowing users to swap out parts in the same g range with few to no testing modifications. This also provides a plug-and-play solution for almost any application.

Will Hyperloops replace trains?

According to the Navigant Research firm, Hyperloop Transportation Technologies has made a deal with central California landowners to build the world's first Hyperloop. The 5-mile test track will be built along California's Interstate 5. The Hyperloop, brought up in 2014 by Tesla Motors CEO Elon Musk, would hypothetically enable passengers to travel in suspended pods through low-pressure tubes at more than 750 miles per hour. Supporters say the Hyperloop has the potential to be a faster, cheaper, and more energy-efficient form of travel than planes, trains, or buses. It is not yet known, however, if the technology is feasible or safe. What do you think? Will Hyperloops replace trains?

Multi-Material, Multi-Color 3D Printing Creates New Possibilities

Major advances in multi-material, multi-color 3D printing technology are driving a fundamental shift in how people are going about designing, engineering, and manufacturing products. The advanced capabilities of state-of-the-art, multi-material, multi-color systems such as the Objet®500 Connex3™ from Stratasys, are opening up many new applications. Making this possible is the Connex3’s ability to produce high-resolution, highly detailed, and functional parts from even the most complex designs. The Connex3 is the world’s first 3D printer that combines multiple materials and colors in a single build. With it, users can simultaneously tailor a part’s material properties, create sharp and well-defined boundaries between different materials, and achieve a sophisticated look and feel that closely mimics a finished product’s aesthetics. This white paper explores the technology at the heart of the Connex3’s performance, and shows how one customer is benefitting from it in many different ways.
