Why Choose the Carlo Gavazzi PA18ALR30TCM6SA Photoelectric Sensor?
The Carlo Gavazzi PA18ALR30TCM6SA is a robust retro-reflective photoelectric sensor designed for reliable object detection in industrial automation. Part of the Carlo Gavazzi PA18 family, it uses a reflector positioned opposite the sensor to return the emitted infrared beam, enabling dependable detection across distances of up to 3000 mm.
The PA18ALR30TCM6SA 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 make it a practical solution for general-purpose sensing on machinery, conveyors and automated production equipment.
Built into a long M18 cylindrical threaded metal housing, the PA18ALR30TCM6SA is engineered for demanding industrial installations. An M12 plug connection simplifies installation and replacement, while IP67 ingress protection and high immunity to ambient light support reliable operation in challenging environments.

Reliable Retro-Reflective Detection for Industrial Automation
Retro-reflective photoelectric sensing places the light emitter and receiver in the same sensor housing and uses a reflector mounted on the opposite side of the detection area. When an object interrupts the returned infrared beam, the sensor changes its output state. This arrangement provides a practical way to achieve reliable detection over longer distances while requiring electrical wiring on only one side of the sensing area.
The Carlo Gavazzi PA18ALR30TCM6SA combines this sensing principle with a rugged M18 metal housing, adjustable sensitivity and a wide AC operating voltage. Its M12 connection and IP67 construction make it particularly suitable for machine builders and automation engineers requiring a durable, easily replaceable retro-reflective sensor.
