There's no need for a matching end point sensor! Thru-beam sensor.
Now, targets that vary in color, surface finish, or angle are detected without issues. Catalogs. They work by having an emitter side that sends out a beam of human-invisible IR light, then a receiver across the way which is sensitive to that same light. Renishaw is a global company with core skills in measurement, motion control, spectroscopy and precision machining. Reflective laser sensor:The sensor head contains both a laser light emitting element and a light receiving element, so it is also called a transmitter/receiver. To detect targets, the sensor emits a laser beam to make it reflect from the surface of the target, and receives the reflected beam to detect the target. We found that it can go a little further depending on the ambient light and the color of the thing distrupting it. This series has a range of up to 5m (16.4') and offers hard wired and M12 connector cable options. It also has easy-to-understand description of the characteristics, technologies, and advantages of various laser sensors.
