Why Choose the Carlo Gavazzi PA18ALD04TCSA Photoelectric Sensor?
The Carlo Gavazzi PA18ALD04TCSA is a robust M18 diffuse-reflective photoelectric sensor designed for reliable non-contact object detection in industrial automation and machinery applications. As part of the Carlo Gavazzi PA18 series, it combines a durable cylindrical metal housing with infrared sensing technology and a wide-range AC power supply.
This sensor uses 880 nm modulated infrared light and a diffuse-reflective sensing principle, allowing objects to be detected without a separate reflector or receiver. Its adjustable sensing system provides a rated operating distance of 0–400 mm, making it suitable for detecting products, components and materials on automated production equipment.
With a 20–250 V AC power supply, two-wire output and normally closed (NC) switching function, the PA18ALD04TCSA is designed for straightforward integration into industrial control circuits. Its M18 threaded metal housing, 2 m cable connection and IP67 protection rating provide a dependable sensing solution for demanding industrial environments.

Reliable Photoelectric Detection for Industrial Automation
Diffuse-reflective photoelectric sensors detect objects by transmitting light towards a target and monitoring the light reflected back to the receiver. Because the transmitter and receiver are contained within the same sensor housing, no separate reflector is required, helping simplify installation on production machinery, conveyors and automated handling systems.
The Carlo Gavazzi PA18 series is designed for general-purpose industrial sensing where compact construction, reliable switching and straightforward installation are important. The PA18ALD04TCSA combines adjustable sensitivity, modulated infrared light and a rugged M18 metal housing to provide dependable detection across a wide range of factory automation applications.
