The Carlo Gavazzi ET1820-1 is a robust through-beam photoelectric emitter designed for reliable object detection in industrial automation, material handling and machine control applications. Part of the Carlo Gavazzi ET18 photoelectric sensor series, it uses modulated infrared light and operates with a separate compatible receiver to create a dependable photoelectric detection system.
Designed around an industrial-standard M18 cylindrical threaded metal housing, the ET1820-1 combines durable construction with a long 20 m maximum sensing range. The emitter uses an 880 nm infrared LED, making it suitable for through-beam installations where reliable detection over significantly greater distances than typical diffuse-reflective sensors is required.
The ET1820-1 operates from a 10–40 V DC supply and features a convenient 4-pin M12 connector for straightforward installation and replacement. Its nickel-plated brass housing, IP67 protection rating and operating temperature range of -20 to +60 °C make it well suited to demanding industrial environments.
Through-beam photoelectric systems use separate emitter and receiver units positioned opposite one another. The emitter projects a beam towards the receiver, and an object is detected when it interrupts this optical path. This operating principle provides excellent detection reliability and enables considerably longer sensing distances than many single-housing photoelectric sensing methods.
The Carlo Gavazzi ET1820-1 is designed as the emitting element of such a system. Its long sensing range, rugged M18 metal construction and DC supply make it particularly suitable for machinery, conveyor systems and industrial installations where dependable non-contact object detection is required.
