Light curtains pick to light for error-free shelf control

Wenglor sensoric light curtain uses a pre-mounted reflector foil attached to the back of the sensor´s housing to reduce the efforts for installation and wiring, reduce the initial start-up costs, and reduce search time.


With its Light Curtains Pick to Light the sensor producer wenglor extends its portfolio of Photoelectronic Sensors. According to the principle "Pick to Light" (commissioning with light) the Light Curtains monitor the correct parts picking processes in shelves and storage locations during mounting and commissioning and thus effectively prevent errors. By using the Light Curtains Pick to Light search times are substantially reduced and productivity is increased. The Light Curtains function according to the retro-reflex principle, meaning that transmitter and receiver are integrated into the same housing and need a reflector in order to function. The practical thing about this: on wenglor´s Light Curtains a reflector foil is already pre-mounted to the back of the sensor´s housing and serves as reflector for the neighboring Light Curtain. This reduces the efforts for installation and wiring and reduces the initial start-up costs.

An integrated two-color job display (green/red) indicates a correct respectively incorrect parts picking process to the user. It is clearly visible at a 360-degree radius to the user and makes a diagnosis possible even when the actual control panel is not visible. The job display can be switched over from blink mode to shine mode, and the output can be switched over from NO to NC. The respective configuration of functions is done with the push of a single button via the Teach key. The Light Curtains in their robust aluminum housings work with visible red light and ensure a range of 2,000 mm. With metering panel heights of 120 mm, 270 mm and 420 mm and a beam spacing of 30 mm the Light Curtains are suited for the use in storage locations as well as for commissioning tasks in the logistics and automotive industries.

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.
