Small laser sensors pack big power

The World-Beam QS18LD Laser Diffuse and QS18LLP Laser Retroreflective sensors from Banner Engineering are designed for high-performance sensing.

The World-Beam QS18LD Laser Diffuse and QS18LLP Laser Retroreflective sensors from Banner Engineering are designed for high-performance sensing, with visible Class 1 lasers, tightly collimated sensing beams and extended sensing ranges.

Both models use the company's popular, compact World-Beam QS18 standard housing for the greatest mounting and application flexibility.

The QS18LD senses targets up to 300mm away, and pricing starts at $99.

The QS18LLP delivers reliable retroreflective sensing up to 10m, and pricing starts at $114.

"As the smallest, most cost-effective models in Banner's extensive laser sensor product offering, the QS18LD and QS18LLP offer tremendous application flexibility when laser sensing power and accuracy are required in a confined location", said Chris Dales, Research and Development Product Planning manager for Banner Engineering.

"Their visible Class 1 lasers deliver an extremely small effective beam for excellent optical performance throughout the entire sensing range - even long distances".

The World-Beam QS18LD and QS18LLP are an excellent fit when high power and small beam sise are important.

They are ideal for a wide range of applications in pharmaceutical, medical, cosmetic, semiconductor, material handling and packaging industries.

Examples include the following: detecting small transitions in a position control application; verifying the presence and location of small holes in a drilling or stamping application; sensing small parts in a conveyance application; and detecting features in an inspection application.

Several features of the World-Beam QS18 laser sensors make them particularly easy to install and use.

Retroreflective models polarise emitted light and filter out any unwanted reflections when detecting shiny objects.

A crosstalk rejection algorithm protects against optical disturbance from adjacent sensors.

A single-turn potentiometer on the back of sensor models allows user adjustment.

Bright green and amber status LEDs are visible from 360.

The compact housing has popular 18mm threaded barrel and two side-mount holes.

There is an extensive offering of versatile mounting brackets is available.

Six connector options are available: 2m or 9m integral cable; 4-pin Euro-style or integral pigtail QD; and 4-pin Pico-style or integral pigtail.

QD World-Beam QS18 laser sensors feature 10 to 30VDC operation and complementary solid-state outputs.

The output is current sourcing (PNP) or current sinking (NPN) depending on model.

World-Beam Series sensors from Banner deliver a universal solution for sensor users who demand a wide range of available sensing modes.

They are easy-to-apply, easy-to-use sensors that resist environmental contamination from moisture, dirt, EMI/RFI and crosstalk.
