WORLD-BEAM QS30AF Sensor Push-Button-SET Adjustable-Field Sensor Features Push-button adjustable-field background suppression sensor detects objects within a defined sensing field, while ignoring objects located beyond the sensing field cutoff Easy cutoff point push-button SET options: Background Suppression SET, Object Detection SET and Dynamic SET, plus manual adjustments. Easy push-button N.O./N.C. and output OFF-delay setup Powerful, highly collimated visible red sensing beam Tough ABS housing is rated IEC IP67 NEMA 6 Easy-to-read operating status indicators, with 8-segment bargraph display Bipolar discrete outputs, PNP and NPN Selectable 30 millisecond OFF-delay Models available with 2 m or 9 m (6.5 or 30 ) cable or integral quick-disconnect Compact housing, mounting versatility via popular 30 mm threaded barrel or side-mount Visible Red, 660 nm Models Model Cutoff Point Cable* Supply Voltage Output Type 2 m (6.5 ) QS30AF 5-wire Cable 50 to 300 mm 10 to 30V dc Bipolar NPN/PNP (2 to 12 ) Integral 5-pin QS30AFQ Euro-style QD * 9 m (30 ) cables are available by adding suffix W/30 to the model number of any cabled sensor (e.g., QS30AF W/30). A model with a QD connector requires a mating cable (see page 9). WARNING . Not To Be Used for Personnel Protection Never use this product as a sensing device for personnel protection. Doing so could lead to serious injury or death. This product does NOT include the self-checking redundant circuitry necessary to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output condition. Consult your current Banner Safety Products catalog for safety products which meet OSHA, ANSI and IEC standards for personnel protection. Printed in USA 08/04 P/N 111384 rev. D WORLD-BEAM QS30AF Adjustable-Field Sensor Yellow Output Conducting Overview Indicator Configuration Green Power ON Push The QS30AF is an easy-to-use triangulation sensor which provides a sophisticated, Indicator Buttons yet cost-effective solution for demanding applications. The sensor features two identically configured outputs, one each NPN and PNP. Bargraph Display The sensors compact housing has a large, easy-to-see bargraph display plus bright LEDs for easy configuration and status monitoring during operation. The Cutoff sensor can be side-mounted, using its integral mounting holes, or front-mounted, Switchpoint via its 30 mm threaded barrel. SETUP Status Indicators: Optical Triangulation Delay Normally Closed The function of the QS30AF Sensor is based on optical triangulation (see Figure 2). The emitter circuitry and optics create a light source which is directed toward a Normally Open target. The light source bounces off the target, scattering some of its light through the sensors receiver lens to its position-sensitive-device (PSD) receiver element. Figure 1. QS30 features The targets distance from the receiver determines the lights angle to the receiver element this angle determines where the returned light falls on the PSD receiver element. The position of the light on the PSD receiver element is processed through digital electronics and analyzed by the microprocessor. The microprocessor will compare the target position to the cutoff limits and then change the outputs as required.
