Control connectors gain UL listing

Line of control connectors, which includes Mini-Quick, Micro-Quick, and Nano-Quick, provides quick disconnects for sensors, proximity switches, valves, and other industrial control devices. These UL-listed connectors use high-strength copper alloy contacts and polyurethane overmolds. Strain relief design uses graduated windows, minimizing the arc of bend and directing strain away from contact terminations. Hubbell, Inc.; www.hubbell-wiring.com

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
