Why Choose the Carlo Gavazzi EO1804PPAS-1 Photoelectric Sensor?

The Carlo Gavazzi EO1804PPAS-1 is a robust M18 diffuse-reflective photoelectric sensor designed for reliable non-contact object detection in industrial machinery and automation systems. Part of the Carlo Gavazzi EO1804 family, it combines a heavy-duty metal cylindrical housing with a PNP complementary NO+NC output, providing both normally open and normally closed switching functions for flexible integration with compatible PLCs and controllers.

Unlike an inductive sensor that detects metal targets, the EO1804PPAS-1 uses modulated 880 nm infrared light to detect objects by their reflected light. Its sensing range is adjustable from 0–400 mm, with sensitivity conveniently set using a 270° single-turn potentiometer. Light-on and dark-on switching capability provides additional flexibility when configuring the sensor for different machine-control requirements.

With a 10–40 V DC supply range, output load capability up to 200 mA and switching frequency up to 120 Hz, the EO1804PPAS-1 is well suited to responsive industrial object detection. Its M12 connector, nickel-plated brass housing and IP67 protection rating provide a durable and service-friendly solution for demanding automation environments.

Reliable Diffuse-Reflective Object Detection

The Carlo Gavazzi EO1804PPAS-1 operates by transmitting modulated infrared light towards the detection area and monitoring the light reflected from an object. Because the emitter and receiver are integrated into the same M18 housing, no separate reflector or opposing receiver is required, making the sensor straightforward to install in many machine automation applications.

Its adjustable 400 mm maximum sensing range allows the detection threshold to be matched to the application, while complementary PNP NO+NC outputs provide flexible control logic. The robust metal housing, M12 connection and protection against short circuits, reverse polarity and electrical transients make the EO1804PPAS-1 particularly suitable for general-purpose industrial sensing.
