Why Choose the Carlo Gavazzi PA18CSD04PAM1SA Photoelectric Sensor?

The Carlo Gavazzi PA18CSD04PAM1SA is an M18 diffuse-reflective photoelectric sensor designed for reliable non-contact object detection in industrial automation, packaging, conveying and machine control applications. Part of the Carlo Gavazzi PA18 series, it combines an industrial-standard cylindrical PBTP housing with integrated amplification and complementary PNP transistor outputs.

Using modulated infrared light, the PA18CSD04PAM1SA detects light reflected directly from the target object, eliminating the need for a separate reflector. Its sensing distance is adjustable up to 400 mm using a 270° sensitivity potentiometer, allowing the sensor to be configured for different target distances and application requirements.

The sensor operates from 10–40 V DC and provides complementary PNP normally open and normally closed outputs with a load current of up to 200 mA. An M12 × 1 connector, compact M18 × 67 mm housing and IP67 protection support convenient installation and dependable service in industrial machinery.

Adjustable Diffuse-Reflective Detection for Industrial Automation

Diffuse-reflective photoelectric sensing uses the target itself to return emitted infrared light to the sensor receiver. When an object enters the sensing zone, the reflected light causes the complementary output circuit to change state, providing contact-free presence detection without the separate reflector required by retro-reflective systems.

The PA18CSD04PAM1SA provides an adjustable sensing distance of up to 400 mm, allowing its detection threshold to be tailored using the built-in sensitivity control. Combined with 100 Hz switching, complementary PNP outputs and an M12 connection, this makes it a practical sensor for component detection, product monitoring and general machine automation.

• Conveyor object and package detection.
• Packaging and processing machinery.
• Component presence and position monitoring.
• Product counting applications.
• Material handling systems.
• Assembly and manufacturing equipment.
