Courtesy: SICKSick's CQ4 capacitive proximity sensor is designed to detect and monitor a wide range of objects and materials. The CQ4 features a miniature IP 67-rated fiber-glass housing that is ideal for industrial applications with limited space. It also has a high switching frequency up to 100 Hz and a sensing range of up to 8 mm, which makes it useful for high-speed object detection through non-metallic surfaces in the electronic and solar, food and beverage, and machine building industries. In addition to detecting objects, the CQ4 provides fill level control for plastic granules, liquids and powders. No holes in the container or tank walls are required, which allows for quick installation.

The CQ4 sensor can be adjusted via potentiometer, ensuring easy and time-saving setup as well as improved adaptability to application requirements. The CQ4 has an operating temperature up to 75 C and can be installed flush in all applications.

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.
