Banner Engineering now offers its World-Beam QS30 diffuse laser sensors that feature a visible laser beam for superior 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 400 mm away from the object for Class I and 700 mm for Class II. This new sensor performs effortlessly in error-proofing applications requiring parts or process event presence detection. Its unique optical design also 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 bar graph displays bright LEDs, providing the user valuable feedback during set-up 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 pushbuttons for security. Disabling the pushbuttons prevents undesired tampering by unauthorised personnel.
Especially significant is the ease and accuracy of set-up with the visible light beam of the laser and the dynamic feedback of an 8-segment LED bar graph display. The QS30 features extremely simple, pushbutton 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 400 mm or Class II laser with an active range of 700 mm. The unit operates from 10 to 30 V d.c. and includes reverse polarity protection, two 150 mA solid-state outputs (NPN and PNP), and transient voltage protection. The popular 30 mm threaded nose, side-mounting holes and special brackets provide numerous mounting options. It features a rugged housing, rated IEC IP67. Users can choose models with a 2 m 5-conductor PVC cable, a 9 m PVC cable, or 5-pin integral Euro-style quick disconnect.
Banner Engineering is the world's leading manufacturer of photoelectric and ultrasonic sensors, fibre-optic assemblies, electronic machine guarding systems, and precision measurement systems.
