Thru-Beam Sensors withstand high-impact applications.

Press Release Summary:




Self-contained BWL L-shaped Sensors have infrared emitter in zinc-plated steel housing that can resist multiple impacts without loss of function. IR light beam cuts through heavily contaminated air with ample reserve capacity. Three sizes are available, with optical axes ranging from 22-42 mm. Sealed to IP67, one-piece plug-and-play sensors feature pre-aligned optics. Maximum response time is 0.5 ms and switching frequency is 1,000 Hz.



Original Press Release:



New L-Shaped Thru-Beam Sensor Brings Easy Setup-Up and Powerful Sensing Capability to 'High Impact' Applications



Combines pre-aligned optics in uniquely shaped steel housing

FLORENCE, KY (January 2005) - Balluff's new BWL L-shaped thru-beam sensor offers versatility and dependability in hard-duty applications where the sensor may be physically contacted or for applications where a fork-style thru-beam design will not fit. The self-contained BWL houses an intense infrared emitter in a rugged, zinc-plated steel housing that can resist multiple impacts without loss of function. Its high power IR light beam will cut through heavily contaminated air with ample reserve capacity, and its configuration promotes easy installation in a wide variety of applications. These include single and side-by-side dual-track conveyor systems (i.e., between the rollers), destacking processes, parts misalignment, and sensing large objects such as metal plates, or completed assemblies.

One-piece "plug and play" BWL sensors feature pre-aligned optics to allow fast, accurate installation without the need for special brackets or complex beam alignment procedures. Three sizes are available, with optical axes ranging from 22-42 mm. Sealed to IP67 protection level, BWL sensors provide ≤ 0.5 ms response time and switching frequency of 1000 Hz.

BWLs allow a level of precision and ease of installation that is a quantum leap over standard fiber optic technology, according to Balluff. BWLs are always in alignment, so they are easy to install; plus, they are accurate over the entire length of the beam, which means they can detect minute deviations over the entire area of a product being manufactured.

Balluff Inc., the U.S. subsidiary of Balluff GmbH & Co., Neuhausen, Germany, is a leading manufacturer of a wide variety of inductive, optical, capacitive and magnetic sensors as well as linear position transducers and ID systems. Balluff products are used to control, regulate, automate, position and monitor manufacturing and packaging sequences for a number of industries, including metalworking, automotive, plastics, aerospace, chemicals and pharmaceuticals, electrical and electronics.
