Minneapolis, MN—Banner Engineering Corp.7月3日推出其新的World-Beam QS30系列仓促roreflective laser sensors. LLP models feature a tiny, tightly collimated laser-sensing beam of 4 mm or less, allowing for precise sensing at up to 18 m, or 60 feet. LLPC models offer superior small object detection, in which the target can actually be smaller than the sensing beam itself. Both sensors feature a visible Class 1 laser and superb optical performance for the highest sensing power and accuracy, two discrete outputs, and an easy-to-read, eight-segment LED bargraph dis-play for status during setup and operation.

‘While the LLP and LLPC models share many of the same physical and component characteristics, they represent two totally unique sensing techniques-each with very specific functions,’ says Joe Dolinsky, technical manager for Banner’s photoelectric products. ‘LLP, with its tightly focused laser spot and maximum excess gain feature, provides a powerful, precise long-range sensing solution that is not easily fooled by diffuse or shiny objects, and operates with exceptional reliability, even in dirty environments. It’s ideal for long-range precise object detection, such as box alignment on a conveyor, or over-height detection.

“The LLPC features excellent low-contrast fine sensing capabilities for reliable detection in traditionally challenging sensing applications involving small or clear objects. It is ideal for detection of wafers and LCD glass, or thread and wire breaks on knitting machines.’

Banner adds that setup is fast and easy for both sensor models with pushbutton programming and an advanced microprocessor design. Both units may be manually SET using the integrated push buttons or via a remote cable that can also be used to disable the push buttons to prevent undesired tampering.

Operating at 10- to 30-V dc, WorldBeam QS30 sensors have a maximum output rating of 150 mA for each of their outputs. These outputs can be set for light operate (N.C.) or dark operate (N.O.), and feature a bipolar configuration with one NPN (current sinking) and one PNP (current sourcing) outputs.
