Courtesy: Banner EngineeringBanner Engineering Corp.'s Q26 Series photoelectric sensor has been added to its line of clear object detection sensors. Featuring a polarized retro coaxial design, the Q26 provides reliable detection of clear, translucent or opaque objects, including mirror-like surfaces. The Q26 is designed for detecting applications such as filling and bottling machines, flat glass or LCD manufacturing, pharmaceutical vials or bag filling machines, or any high-speed application where positioning is critical.

The Q26 features a compact cubic shape with 20 mm mounting hole spacing, enabling quick installation in tight locations. Additionally, the sensor’s coaxial optics permit operation over a wide range of distances with the reflector mounted as close as 5 mm for applications with restricted spaces.

The Q26 includes a LO/DO switch to control the output type, and a single turn potentiometer to adjust detection sensitivity. Equipped with a Health Mode output for application monitoring, the Q26 communicates operation and connection status—allowing the user to ensure reliable sensor performance.

The Q26 operates on 12-30V dc with a response speed of 250 microseconds. The sensor is also protected against damage from potential miswiring during installation and transient voltage spikes during operation.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
