Photoelectric sensors have high-function reserve, rugged housing

The BOS 18M photoelectric sensors from Balluff have exact switching response and use LED technology that allow the sensors to be used in indoor settings or in daylight.

BOS 18M photoelectric sensors from Balluff feature a generous sensing distance and high function reserve. Models include energetic diffuse, retro-reflective and thru-beam, which are available as red light and infrared types. The series of red light sensors also includes a version with high-performance background suppression.

Common to all the sensors is the uniform, rugged metal housing. The LED technology and Fresnel lenses ensure sharp contours which precisely reproduce the switching area. This means the sensors can even be used in daylight or strongly illuminated indoor areas and can be quickly and precisely aligned. With their exact switching response and repeat accuracy, the BOS 18M sensors are ideal for demanding positioning tasks. Optical band-pass filters provide extremely high ambient light rejection from sunlight or other artificial light sources.

All red light and infrared models feature a potentiometer for precise setup. Adjustment is also aided by highly visible LED indicators. For users who prefer the teach-in procedure for setup, the red light sensors (energetic diffuse, retro-reflective and thru-beam) are available in corresponding versions.

The BOS 18M with background suppression are unique. These are the only sensors of their kind to be equipped with a sensitive multi-turn potentiometer for setting the distance down to millimeter accuracy. The range of up to 300 mm is also reliable when the target is a dark object. These sensors also stand out with their very low gray value shift at close range (~1% at 100 mm). This enables color-independent object detection even against reflective backgrounds.

Objects with notches, holes or cut-outs are often a challenge for sensors – but not for the BOS 18M, since these gaps are simply bridged by the large light spot. This allows even coil springs for example to be reliably detected regardless of orientation.

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.
