AutomationDirect offers the Cutler-Hammer Enhanced 50 series of high-performance photoelectric sensors, manufactured by Eaton, which includes thru-beam, polarized reflex, diffuse and clear object models, designed in a rugged industry-standard rectangular package. Available sensing ranges vary from 45 inches to 500 ft. Flexibility of input supply voltages (10-40V dc and 12-240V dc/24-240V ac) and output types (relay, transistor, or solid-state relay) makes system integration easy. Features include light/dark operation selection, gain adjustment and multi-color LED indicators. All sensors are IP67 rated, and are available with a variety of cabling choices, including micro and mini quick-disconnect styles or a 6-ft integrated cable. Matching cables and mounting brackets are also available. AutomationDirect http://rbi.ims.ca/4912-536
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
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.
