Carlo Gavazzi Long Range Photoelectric Sensor

Carlo Gavazzi launches a new long range diffuse photoelectric sensor with background suppression technology. The Carlo Gavazzi PD112 will detect black objects at distances up to 2 meters, and white and gray objects at up to 2.5 m. Using triangulation technology, the PD112 can be easily and precisely adjusted, with a 28 turn potentiometer, company says. The user can fine tune the sensor to detect the target at the desired distance and ignore reflective objects only millimeters beyond.

D112 features make it simple to use and highly versatile, company says. Each model has both NPN and PNP output, which is automatically detected by the sensor when wired. Normally open or normally closed output can be selected via a dip switch. Two adjustable timers (1 - 16 seconds) for ON and OFF delay allow for a customized solution.

In talking about the sensor Carlo Gavazzi called the PD112's mode operation selection a "truly innovative feature." The sensor can be operated in a traditional industrial mode, ideal for applications such as material handling, packaging and wrapping, and wood processing. With a simple dip switch selection, the PD112 also can be operated in a door mode, which automatically optimizes sensor performance for detecting people and objects around automatic doors. This mode allows the sensor to be remotely tested by a door controller, making the sensor compliant with door industry safety standards.

D112 is available with a cable or M12 plug and carries UL and CE approvals, providing assurance of a high quality and safe product, company says.

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.
