Industrial safety light curtain protects fingers, hand, body

ifm Type 4 light curtains provide finger, hand, and body protection and continuously monitors itself for faults and monitors the surrounding area with an infra-red beam.


ifm Type 4 light curtains provide finger, hand and body protection and continuously monitors itself for faults and monitors the surrounding area with an infra-red beam. Courtesy: ifmifm's low-profile safety light curtains provide finger, hand and body protection in a variety of industrial applications. ifm Type 4 light curtains provide a multi-beam barrier of infrared light in front of a hazardous area. If any of the beams are blocked by an object, such as a finger or a hand, the light curtain sends a signal to the machine to place it in a safe state. ifm light curtains are offered in protective heights of 160 mm to 1510 mm in increments of 150 mm. The light curtain’s slim housing design measures only 28 x 30 mm that fits easily in an application for less intrusive mounting. Simple installation does not require software or control boxes and meets safety level requirements according to IEC61496; SIL 3, SILcl 3 and PL e.

ifm’s Type 4 light curtain continuously monitors itself for faults. A tight effective aperture angle of 2.5° reduces risk of optical short circuits, and the curtains include duplicate critical components and circuits in order to provide a back-up system should the primary system fail. Reset functionality and protected area width are configured without the use of DIP switches or complex software.  Redundant safety rated solid-state outputs ensure fast response time. Bright LEDs indicate power, system status and fault conditions. Power is achieved with an M12 connection.

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.
