Laser adjustable-field sensors with standard housing

May 2006 Sensors & Transducers

Banner Engineering is offering its World-beam QS18 Laser adjustable-field sensors. They deliver high-performance sensing with a visible Class 1 laser, tightly collimated sensing beams and precision background suppression.

"QS18LAF sensors feature our compact World-beam housing for the greatest mounting flexibility, yet they deliver high power and provide a sharp cut-off," said Brad Johnson, application engineer for Banner Engineering. "The narrow visible beam is perfect for small object detection and precision position control. The QS18LAF accurately detects hard to see objects, even on dark background, such as recessed, milled or bored holes that do not fully penetrate a material. The compact housing makes it a good choice for background suppression applications in small, difficult-to-reach areas."

Applications

These sensors are suitable when high power and small beam size are important. They are good for a wide range of applications in the metal stamping, packaging, material handling, semiconductor and pharmaceutical industries. Examples include the following:

* Detecting small transitions in a position control application.

* Verifying the proper die in a stamping application.

* Sensing small parts in a conveyance application.

* Detecting tiny features in an inspection application.

* Error proofing in a packaging application.

Several features of the World-beam QS18LAF sensors make them particularly easy to install and use:

* Adjustable-field background suppression sensors sense small parts of varying colours while ignoring the background.

* Crosstalk rejection algorithm protects against optical disturbance from adjacent sensors.

* Multiturn potentiometer on the top of sensor models allows user adjustment.

* Bright green and amber status LEDs are visible from 360°.

* Compact housing has two side-mount holes.

* An extensive offering of versatile mounting brackets are available.

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