BANNER Engineering has announced new World-Beam QS30 diffuse laser sensors, available from Micromax , that feature a visible laser beam for ease of alignment and long-range diffuse-mode sensing capabilities.
The QS30 is an easy-to-use, high-performance laser sensor whose many configuration options make it suitable for demanding applications.
It provides high-performance sensing in low-contrast applications up to 400mm away from the object for Class I and 700mm for Class II.
Its unique optical design permits use through transparent walls for hopper or view-port applications and accurate feature detection, such as presence of threads on a bolt or tapped into an opening.
It can also be used for edge detection, end of material detection or overheight identification.
The easy-to-see bargraph displays bright LEDs, providing the user valuable feedback during setup and operation. For maximum efficiency and convenience, one or more sensors can be programmed from an external switch or PLC, via a remote TEACH wire.
The wire can also be used to disable the push buttons for security. Disabling the push buttons prevents undesired tampering by unauthorised personnel.
Significant is the ease and accuracy of setup with the visible light beam of the laser and the dynamic feedback of an 8-segment LED bargraph display.
The QS30 features simple, push-button single or two-point static, and two-point dynamic TEACH programming, plus a manual adjustment mode for fine-tuning.
Static TEACH computes each sensing condition individually after the good and bad conditions are presented.
Dynamic TEACH is used to program the sensor "on-the-fly" during actual machine-run conditions by taking multiple samples of the light and dark conditions and automatically setting the threshold at the required level.
The QS30 diffuse laser is available in a Class I laser format with a range of 400mm or Class II laser with an active range of 700mm.
The unit operates from 10 to 30V dc, and includes reverse polarity protection, two 150mA solid state outputs (NPN and PNP), and transient voltage protection.
The 30mm threaded nose, side-mounting holes and special brackets provide numerous mounting options. It features a rugged housing, rated IEC IP67 and NEMA 6. Users can choose models with a 2m, 5-conductor PVC cable, a 9m PVC cable, or 5-pin integral Euro-style quick disconnect.
