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 National Highway Traffic Safety Administrationís recent backup camera mandate could open the door to more vehicle innovations, including better graphical displays, 360-degree camera views, and the increased use of Ethernet.
With support from National Instruments, a group of dedicated students from Connally High School in Austin, where more than 50% of the students are at risk of not graduating, have created a successful robotics team that is competing in the FIRST World Championships.
