Convergent laser sensor

PicoDot is a Class II convergent-beam laser sensor that features a precise convergent point size of 0.25 mm at its focal distance, making it well suited to wafer mapping applications. The unit provides an overall sensing distance of 50-115 mm with a focal distance of 100 mm; and its small size (40 ? 45 ? 12.7 mm) and light weight suit it for use on robotic end effectors. PicoDot`s sensing response time is 0.2 milliseconds, allowing its use in high-speed applications such as lead or pin counting. It operates from 10-30 Vdc and is available with either NPN or PNP output. Banner Engineering Corp., Minneapolis, MN; ph 612/595-3797, fax 612/544-3213.
