Why Choose the Carlo Gavazzi PA18ALD04TCM6SA Photoelectric Sensor?
The Carlo Gavazzi PA18ALD04TCM6SA is a robust M18 diffuse-reflective photoelectric sensor designed for reliable object detection in industrial automation and control applications. As part of the Carlo Gavazzi PA18 series, it combines a durable metal threaded housing with infrared sensing technology and a versatile wide-range AC supply.
This sensor uses 880 nm infrared modulated light to detect objects without requiring a separate reflector or receiver. Its adjustable diffuse-reflective sensing system provides a rated operating distance of up to 400 mm, making it suitable for detecting products, components and materials on automated machinery and production equipment.
With a 20–250 V AC power supply, two-wire SCR output and normally closed (NC) switching function, the PA18ALD04TCM6SA is designed for straightforward integration into industrial control circuits. Its M18 cylindrical threaded metal housing, M12 connector and IP67 protection rating provide a practical solution for demanding factory 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 and automated handling systems.
The PA18 series is designed for industrial detection applications where compact construction, reliable switching and straightforward mounting are important. The PA18ALD04TCM6SA combines adjustable sensitivity, infrared sensing and a rugged metal M18 housing to provide dependable detection across a wide range of automation tasks.
Typical Applications
- Object detection on industrial conveyor systems.
- Packaging and production machinery.
- Product counting and positioning applications.
- Material handling and automated assembly equipment.
- Detection of containers, components and manufactured parts.
- Factory automation and machine building.
