Molded Nylon Special Standard Round Spacers
Micro Plastics announces a new product line of Special Standard Round Spacers. The new line of molded nylon round spacers includes over 250 sizes, with diameters of 1/8" through 1 1/2" and lengths from 1/8" to 2 3/4". These tough, resilient spacers can be used in a variety of assemblies. Useful in electronic and electrical applications, they may also be used as bushings, bearings, rollers, gliders, and bumpers. They are resistant to vibration, abrasion, and corrosion; are electrically insulating; and have a high strength-to-weight ratio.

Open-thermistor temp sensors use fused glass to eliminate leakage

Fused glass is key to providing the leak-proof operation of these new open thermistor-type temperature sensors from Gems Sensors & Control. The TM-950 Series temp sensors use an open (exposed) thermistor design for faster response to temperature fluctuation than can be achieved with closed (encapsulated) designs. This series solves the sensed fluid leakage problem common with other open thermistor type sensors currently available. Originally designed for oil and refrigerants in HVAC and chiller systems, TM-950 sensors can be used to monitor temperatures in any non-conductive fluid.

Smart honing technology puts lift in business for aerospace hydraulic pumps

A new honing technology from Sunnen makes a 60-millionths tolerance look generous. "We don't believe it!" That's how experienced machinists reacted to their first encounter with the machine tool that had produced nine bores per part with only 0.000020 in. variation, all day long, with essentially no operator attention.

New 'tunable white' LED with high CRI

The new Osram Ostar Medical from Osram Opto Semiconductors is the first LED component with a high color-rendering index (CRI) of 95 and the possibility of adjusting the temperature of the color white. This combination of precise chromaticity coordinate control and excellent CRI is particularly important for lighting in the medical sector. With a footprint of just 5.9 mm x 4.8 mm and a housing height of 1.2 mm, the design of the Osram Ostar Medical is only about one-quarter as high as the components ordinarily used.

Micro robotic tool changer

The QC-001 Micro Robotic Tool Changer, recently developed by ATI Industrial Automation, is ideal for high-speed "spider" or parallel-link robots, enhancing their ability to switch end-effectors automatically. This compact and lightweight tool changer allows for multiple assembly, dispensing, sorting, and material handling operations to be performed by one robot, which can greatly increase productivity while reducing downtime for changeovers. The QC-001 Micro Tool Changer weighs less than 122 g (4.3 oz), handles payloads of up to 1.4 kg (3 lb), and features integrated pneumatic ports and electrical connections. Additional features include: patented Fail-Safe locking mechanism to ensure high-moment capacity and strength; a common Lock/Unlock air supply and a Lock/Unlock sensing method; four M5 pass-through air connections, eight 3-A/50-VAC electrical connections, and a stack height of only 16.9 mm (0.67 in.).

New high-accuracy magnetic encoder

Novotechnik U.S. introduces the Vert-X 51 Series of rotary magnetic encoders that feature 12-, 14-, or 16-bit resolution and repeatability to 0.36 deg or +/-0.1 deg, depending on model. These encoders are ideal for harsh environments with ingress protection to IP 67, withstand shock up to 50 g and vibration to 20 g, and have an operating and storage temperature range of up to -40 deg C to 125 deg C. MTBF is 135+ years. Measurement range is 0 deg to 360 deg, and physical measurements of the housing are 30 mm x 50 mm. Ten output options are available.

Energy harvesting's spark of innovation:
Triboelectric generators capture wasted power

With one stomp of his foot, Zhong Lin Wang illuminates a thousand LED bulbs -- with no batteries or power cord. The current comes from essentially the same source as that tiny spark that jumps from a fingertip to a doorknob when you walk across carpet on a cold, dry day. Wang and his research team have learned to harvest this power and put it to work.

Air-flow design that's simply a breeze
Autodesk Flow Design is a new simulation tool that enables designers to visualize airflow around any object. With Flow Design, designers are able to introduce air-flow simulation from the conceptual level all the way through to the completed model, ensuring they are making educated design decisions at every stage of the process. As your own personal 24/7 wind tunnel, this tool is intuitive enough that someone without any simulation expertise can run limited analysis, which makes collaboration between designers, engineers, and analysts more effective and efficient.
