Why Choose the Carlo Gavazzi PA18ALP20TCM6SA Photoelectric Sensor?
The Carlo Gavazzi PA18ALP20TCM6SA is a robust polarised retro-reflective photoelectric sensor designed for reliable object detection in industrial automation, material handling and machine control systems. As part of the Carlo Gavazzi PA18 series, it combines a durable threaded metal barrel housing with simple adjustment and dependable optical sensing.
The sensor uses polarised red modulated light to detect objects between the sensor and a suitable reflector, helping improve immunity to unwanted reflections from shiny surfaces. Its two-wire normally closed output and wide AC operating voltage range make it suitable for straightforward integration into industrial control circuits.
With a sensing distance of up to 2000 mm, a 20–250 V AC supply and an M12 connector, the PA18ALP20TCM6SA provides a practical sensing solution for production machinery, conveyors, packaging equipment and general factory automation.

Reliable Photoelectric Detection for Industrial Automation
Polarised retro-reflective sensors operate by transmitting light towards a reflector and monitoring the returned beam. When an object interrupts the reflected light path, the sensor changes its output state, allowing machinery and automation systems to identify the presence or absence of materials, components or packages.
The PA18ALP20TCM6SA uses polarised light to improve discrimination between the intended reflector and reflections from shiny objects. Its metal M18 housing, IP67 protection and wide AC operating range make it particularly well suited to general-purpose industrial sensing applications.
