Why Choose the Carlo Gavazzi PD30CNB25PAPS Background-Suppression Photoelectric Sensor?
The Carlo Gavazzi PD30CNB25PAPS is a compact diffuse-reflective photoelectric sensor with adjustable background suppression designed for precise object detection in industrial automation and machine-building applications. As part of the Carlo Gavazzi PD30 PointSpot photoelectric sensor series, it combines focused red-light sensing with reliable PNP complementary outputs in a slim rectangular housing.
The PD30CNB25PAPS provides a sensing distance of up to 250 mm and uses 625 nm red light with PointSpot optics. Its background-suppression principle allows the sensor to distinguish the intended target from objects or surfaces located behind it, improving detection reliability where conventional diffuse-reflective sensing could be affected by the background.
Operating from a 10–30 V DC supply, the sensor provides PNP complementary NO+NC outputs with selectable light/dark switching. A pre-wired 2 m cable, compact 10 × 30 × 20 mm ABS housing and IP67 protection make the PD30CNB25PAPS well suited to space-constrained industrial installations.

Reliable Background Suppression for Industrial Automation
Background-suppression photoelectric sensors evaluate reflected light so that objects within the configured sensing range can be detected while more distant surfaces are ignored. This makes them particularly useful where the target moves in front of machine panels, conveyor structures or other backgrounds that could otherwise cause unwanted switching.
The PD30CNB25PAPS combines PointSpot red-light optics, adjustable background suppression and complementary PNP outputs in a compact housing. Its fast switching performance and clearly visible sensing spot make alignment straightforward and support accurate detection of products, components and workpieces in automated machinery.
Typical Applications
- Product presence detection on conveyors.
- Packaging and processing machinery.
- Component position and orientation sensing.
- Assembly and manufacturing equipment.
- Detection where a nearby background must be ignored.
- Counting and sorting systems.
- OEM machinery and factory automation.
