Precision Cutoff Sensor Offers Accurate Object Detection Regardless of Color or Background
Minneapolis, MN-February 19, 2003-Banner Engineering Corp. has announced new WORLD-BEAM® QS30AF high-accuracy adjustable-field sensors. Designed to sense objects in challenging applications where the target and its background have similar color or reflective qualities, the powerful visible red sensing beam and precision background suppression circuitry allow the sensor to detect only objects within the defined sensing field while ignoring objects beyond a cutoff point of up to 300 mm (12"). "This is an easy to use triangulation sensor with an advanced microprocessor and position-sensitive-device (PSD) receiver element, it offers accurate detection of a very precise target location -and is a cost-effective solution at just $129.00" said Joe Dolinsky, Technical Manager for Banner's photoelectric products. "The QS30AF is ideal for error proofing, feature detection, edge detection, material runout, proper fill level or presence and absence detection for applications in packaging, material handling, printing, automotive and the feederbowl industry" Dolinsky added.
The QS30AF's advanced microprocessor simplifies setup and the dynamic feedback of its 8-segment LED bargraph display adds additional flexibility, clearly showing unit status as it is constantly updating. With extremely simple, push-button-SET programming the user merely needs to establish a background point to be ignored or the object to be sensed. In Dynamic SET, which is used to program the sensor "on-the-fly" during actual machine-run conditions, the sensor takes multiple samples of the reflective conditions and automatically sets the cutoff point half-way between the target and background. Dynamic SET is programmed through a remote wire, which can also be used to disable the push buttons to prevent undesired tampering at the sensor.
"An addition to Banner's WORLD-BEAM family of sensors, the QS30AF features the universally accepted 30 mm threaded housing and a broad assortment of mounting brackets. This compliments our background suppression product offering nicely and really offers Banner customers a choice of sensors for every application" Dolinsky also stated.
The 10 to 30V dc QS30AF background suppression sensor has a maximum output rating of 150 mA for each of its outputs. It can be set for light operate (N.O.) or dark operate (N.C.), and feature a bipolar configuration with one NPN (current sinking) and one PNP (current sourcing) outputs. The sensors tolerate
vibration, mechanical shock, and washdown. Internal circuitry guards against false pulse on power-up, continuous overload, and short circuit of outputs.
The QS30AF's tough ABS/ polycarbonate blend housing meets IEC IP67 and NEMA 6 standards and operates in temperatures of -10°C to +55°C (+14°F to +131°F). The sensors are available with a 2 m (6.5') PVC cable, 9 m (30') PVC cable or 5-pin integral Euro-style quick-disconnect cable. List prices begin at $129.00.
