Sensing With Lasers

The LLP models feature a small, tightly collimated laser sensing beam of 4 mm or less, allowing for precise sensing at ranges up to 18 m. These models are ideal for long-range precise object detection such as box alignment on a conveyor, or overheight detection, says the vendor. The LLPC models are designed for small object detection where the target can be smaller than the sensing beam itself. These models feature low-contrast fine sensing capabilities for reliable detection in challenging sensing applications involving small or clear objects, such as wafers and LCD glass, or for detecting thread or wire breaks on knitting machines. Both sensor models rely on a visible Class 1 laser. They offer two discrete outputs and an easy-to-read 8-segment LED bargraph display for status during set-up and operation.
