Why Choose the Carlo Gavazzi PD30CTB20PAIS Background-Suppression Photoelectric Sensor?
The Carlo Gavazzi PD30CTB20PAIS is a compact diffuse-reflective photoelectric sensor with adjustable background suppression designed for precise object detection in industrial machinery and automation systems. As part of the Carlo Gavazzi PD30 photoelectric sensor series, it combines a 200 mm sensing range with infrared detection, PNP complementary outputs and a convenient top-mounted adjustment trimmer.
The PD30CTB20PAIS uses infrared light and background-suppression technology to detect objects within the configured sensing zone while ignoring more distant surfaces. This helps improve detection reliability where machine panels, conveyor structures or other background objects could otherwise interfere with conventional diffuse-reflective sensing.
Operating from a 10–30 V DC supply, the PD30CTB20PAIS provides PNP complementary NO+NC outputs with light and dark switching functionality. Its 2 m pre-wired cable, compact rectangular housing, fast switching performance and IP67 protection make it well suited to demanding industrial automation applications.

Reliable Background Suppression for Industrial Automation
Background-suppression photoelectric sensors are designed to detect objects within a defined sensing range while rejecting reflections from more distant surfaces. This makes them especially useful in machinery where targets pass in front of conveyor frames, guards, panels or other background objects that could otherwise cause false switching.
The PD30CTB20PAIS combines adjustable background suppression with infrared sensing and complementary PNP outputs in a compact industrial housing. Its top-mounted trimmer allows the sensing threshold to be configured conveniently after installation, making it a practical choice for machine builders and automation engineers requiring dependable close-range detection.
Typical Applications
- Product presence detection on conveyors.
- Packaging and production machinery.
- Component positioning and assembly systems.
- Detection where background surfaces must be ignored.
- Counting and sorting equipment.
- Material handling systems.
- OEM machinery and factory automation.
