Through-beam laser sensors detect objects
BEA LASERS Eagle Eye Sensors contains both a through-beam photoelectric laser source (emitter) and a receiver, providing a similar function as a proximity sensor, but with enhanced benefits. The combination emitter/receiver package is ideal for detecting the presence of objects, such as products on an assembly line, material or liquid level control, product positioning or profiling, and other applications. The housing and components are ruggedized to withstand the ambient stresses of a factory environment and the set is also IP67 rated. Products are available with a red (650nm) laser, and a dot optic. The laser is pulsed / modulated, which helps the receiver to distinguish the signal from extraneous light and achieve a long sensing range. The maximum operating distance between the emitter and the receiver, or sensing range, is 20 meters.
