Why Choose the Carlo Gavazzi ET1820PPAS Through-Beam Photoelectric Receiver?
The Carlo Gavazzi ET1820PPAS is an industrial through-beam photoelectric receiver designed for reliable long-range object detection in machinery, conveying and automation systems. Part of the ET1820 series, it features a robust M18 cylindrical threaded metal housing and is intended for use with the corresponding ET1820 through-beam emitter.
The ET1820PPAS provides a sensing range of up to 20 m with adjustable sensitivity and uses 880 nm modulated infrared light. Its complementary PNP NO+NC outputs support both light-on and dark-on switching, giving machine builders and system integrators flexibility when configuring detection logic.
Operating from a 10–40 V DC supply, the receiver can switch loads up to 200 mA and provides a typical switching frequency of 170 Hz. The cable-connected version uses a durable nickel-plated brass housing with IP67 protection and is supplied with a 2 m cable for straightforward installation in industrial environments.

Reliable Long-Range Detection for Industrial Automation
Through-beam photoelectric sensing uses a separate emitter and receiver positioned opposite each other, providing reliable detection when an object interrupts the light beam. With a rated operating distance of up to 20 m, the ET1820PPAS is well suited to applications requiring dependable detection over significantly greater distances than typical diffuse or retro-reflective sensors.
The combination of adjustable sensitivity, PNP NO+NC outputs and light-on or dark-on operation gives designers flexibility when integrating the receiver into machine control circuits. Its 170 Hz typical switching frequency, IP67 metal construction and electrical protection functions make it suitable for demanding automated machinery and material-handling installations.
Typical Applications
- Conveyor object detection.
- Material-handling systems.
- Packaging and processing machinery.
- Automated production equipment.
- Presence and position detection.
- Long-range object detection.
- Warehouse and logistics automation.
- Industrial machine control systems.
