Why Choose the Carlo Gavazzi PD30CNB20PASA Photoelectric Sensor?
The Carlo Gavazzi PD30CNB20PASA is a compact and reliable diffuse-reflective photoelectric sensor with adjustable background suppression designed for precise object detection in industrial automation and machine control applications. As part of the Carlo Gavazzi PD30 series, it combines a sensing range of up to 200 mm, visible red light and complementary PNP outputs in a compact rectangular housing.
The PD30CNB20PASA uses 625 nm modulated red light and background suppression technology to detect target objects while ignoring surfaces beyond the selected sensing distance. Its adjustable sensitivity enables the detection point to be matched to the application, helping provide stable operation where objects must be distinguished from nearby machine backgrounds.
Operating from a 10–30 V DC supply, the PD30CNB20PASA provides PNP complementary NO+NC outputs with light and dark switching. A 2 m integral cable, fast 500 Hz switching frequency and IP67 housing make it well suited to conveyors, packaging equipment, assembly machinery and other industrial automation systems.

Reliable Background-Suppressed Detection for Industrial Automation
Background-suppression photoelectric sensors such as the Carlo Gavazzi PD30CNB20PASA detect light reflected from the target while using optical triangulation to reject objects or surfaces beyond the selected sensing point. This makes them particularly useful where a conventional diffuse-reflective sensor could be influenced by a nearby conveyor, machine panel or other background.
The PD30 series combines compact dimensions with adjustable sensing and fast solid-state switching. The PD30CNB20PASA provides a 200 mm sensing range, complementary PNP outputs and visible red light, allowing machine builders to implement reliable object presence and position detection in space-constrained automated equipment.
Typical Applications
- Industrial conveyor and material handling systems.
- Packaging and production machinery.
- Object presence and position detection.
- Component detection against nearby backgrounds.
- Parts counting and product monitoring.
- Assembly and automated manufacturing lines.
- Handling and pick-and-place equipment.
- OEM machinery and industrial automation systems.
