pd40cnb08np – photo br pl 80mm npn no+nc cab
Carlo Gavazzi PD40CNB08NP is a compact diffuse-reflective photoelectric sensor with background suppression, an adjustable 15–80 mm sensing range, 10–30 V DC supply, complementary NPN NO + NC outputs and a 2 m cable for precise industrial object detection.
Why Choose the Carlo Gavazzi PD40CNB08NP Photoelectric Sensor?
The Carlo Gavazzi PD40CNB08NP is a compact diffuse-reflective photoelectric sensor with background suppression designed for precise short-range object detection in industrial machinery and automation systems. Part of the Carlo Gavazzi PD40 series, it provides an adjustable sensing distance of approximately 15–80 mm, making it particularly suitable for detecting components where nearby machine structures or surfaces could otherwise interfere with sensing.
Background suppression allows the PD40CNB08NP to respond to the intended target while reducing unwanted switching caused by objects beyond the selected sensing distance. Its NPN transistor output with complementary NO + NC switching provides flexible integration with compatible PLCs, machine controllers and other industrial automation equipment.
The PD40CNB08NP operates from a 10–30 V DC supply and offers an operating frequency of 250 Hz. This version is supplied with a 2 m fixed cable and features a compact 20 × 32 × 10 mm ABS housing with IP67 protection, providing a practical sensing solution for space-restricted industrial machinery.

Precise Short-Range Detection with Background Suppression
Diffuse-reflective photoelectric sensors detect objects using light returned directly from the target, eliminating the need for a separate reflector or receiver. Background suppression adds distance discrimination so that the sensor can respond to objects within the selected sensing zone while reducing unwanted response to machine panels, conveyor surfaces and other structures located farther away.
The Carlo Gavazzi PD40CNB08NP combines this sensing principle with an adjustable 15–80 mm range and compact industrial housing. This makes it well suited to applications where precise short-range presence or position detection is required and installation space is limited.
Typical Applications
- Small-component presence detection.
- Packaging and production machinery.
- Short-range conveyor object detection.
- Assembly and handling equipment.
- Component position and orientation monitoring.
- Automated counting and inspection systems.
- Compact PLC-controlled machinery and factory automation.
