Capacitive proximity switch has high-resolution analog output
Lion Precision’s CPA100 Capacitive Sensor proves standard measurement ranges from .05 mm to 6 mm.
The CPA100 Capacitive Sensor from Lion Precision has a setpoint (switched) output to indicate presence/absence like a typical proximity switch, but the nonlinear analog output is capable of resolutions as low as 15 nm RMS (150 nm p-p). The sensor features a unique front panel range indicator to alert the operator to out-of-range conditions, DIN rail mount electronics, and user adjustments for Offset (Zero) and Gain. A selection of probes provides standard measurement ranges from 0.05 to 6 mm. Offset and Gain can also be controlled with remote potentiometers if the device is enclosed in a control panel. Sync connectors allow interference-free use of multiple sensors with the same target.
Typical applications for the CPA100, besides basic position monitoring, include production line part sorting; double sheet detection in printers or related processes; and monitoring of processes involving nonconductive materials such as films, fabrics, and applied coatings such as adhesives.

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.
