Why Choose the Carlo Gavazzi PA18ALR30TCSA Photoelectric Sensor?
The Carlo Gavazzi PA18ALR30TCSA is a robust retro-reflective photoelectric sensor designed for dependable object detection in industrial automation. Part of the Carlo Gavazzi PA18 Series, it uses a reflector to return the emitted infrared beam and provides a sensing range of up to 3000 mm.
The PA18ALR30TCSA operates from a wide 20–250 V AC supply and features a two-wire normally closed (NC) output. Its modulated 880 nm infrared light, dark-switching operation and adjustable sensitivity provide a practical sensing solution for conveyors, packaging equipment, material handling systems and general industrial machinery.
Designed for heavy-duty applications, the sensor uses a long M18 cylindrical threaded metal housing with durable nickel-plated brass construction. This cable-connected version is supplied with an integral 2 m cable, while IP67 ingress protection, LED output indication and high immunity to ambient light support reliable operation in demanding industrial environments.

Reliable Retro-Reflective Detection for Industrial Automation
Retro-reflective photoelectric sensing places the emitter and receiver within the same sensor housing and uses a reflector installed on the opposite side of the detection area. An object is detected when it interrupts the returned infrared beam, allowing reliable non-contact detection while requiring electrical wiring on only one side of the application.
The Carlo Gavazzi PA18ALR30TCSA combines this proven sensing principle with a rugged M18 metal body, adjustable sensitivity, wide AC operating voltage and integral cable. Its long sensing range and IP67 construction make it a practical choice for machine builders and automation engineers requiring a durable retro-reflective sensor for general industrial applications.
