Why Choose the Carlo Gavazzi PA18ALP20TCSA Photoelectric Sensor?
The Carlo Gavazzi PA18ALP20TCSA is a robust polarised retro-reflective photoelectric sensor designed for dependable object detection in industrial automation, material handling and machine control applications. As part of the Carlo Gavazzi PA18 series, it combines reliable optical sensing with a durable M18 threaded metal housing suitable for demanding industrial environments.
This sensor uses polarised red modulated light and a reflector to detect objects passing through its optical path. Polarisation provides improved immunity to reflections from shiny surfaces, while adjustable sensitivity allows the sensor to be configured for the requirements of the application.
With a sensing range of up to 2000 mm, a 20–250 V AC supply, a two-wire normally closed (NC) output and an integral 2 m cable, the PA18ALP20TCSA provides a practical solution for conveyors, packaging machinery and general factory automation.

Reliable Photoelectric Detection for Industrial Automation
Polarised retro-reflective photoelectric sensors transmit light towards a reflector and monitor the returned beam. When an object interrupts the optical path, the sensor changes its switching state, allowing automated machinery to detect products, components and materials without physical contact.
The PA18ALP20TCSA combines this sensing principle with a rugged metal M18 housing, adjustable sensitivity and IP67 protection. Its polarised optical system helps distinguish the intended reflector from unwanted reflections, making it particularly useful where shiny or reflective objects are present.
Typical Applications
- Conveyor object and package detection.
- Packaging and bottling machinery.
- Production and assembly equipment.
- Material handling and logistics systems.
- Product counting and presence detection.
- Industrial machine position monitoring.
