Humphrey's valves are a compact 1/8 inch ported 3- and 4-way, designed to work in a number of pneumatic applications. Valves from the same series can be mounted on a subbase or in-line, and 310 and 410 valves can go together on manifolds. They offer positive sealing, with a short-stroke balanced poppet design that doesn't need lubrication, is more tolerant of impurities in the air system and allows rapid cycling. The 310 series valves have a 0.12 Cv, and the 410 series has a 0.14 Cv. Both types have an air and inert gas rating from vacuum at 28 inches Hg to 125 psig. A continuous duty coil consumes 4.0W, comes in a range of ac and dc voltages, has flying leads and comes with a standard push, non-locking manual override. Options such as dc surge suppression and ac MOV, conduit connector with steel insert molded into the coil, plug-in, DIN-type connectors and a locking override are available. The 410 series can save space, weight and the cost of external flow controls with optional built-in flow controls.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
