pb15inpa-1 – photo bs pl npn no+nc plg
Carlo Gavazzi PB15INPA-1 is a diffuse reflective photoelectric sensor with background suppression, adjustable 150 mm sensing distance, NPN NO + NC outputs and an M12 connector for industrial automation applications.
Why Choose the Carlo Gavazzi PB15INPA-1 Photoelectric Sensor?
The Carlo Gavazzi PB15INPA-1 is a compact and reliable diffuse reflective photoelectric sensor with background suppression designed for object detection in industrial automation and machinery applications. As part of the Carlo Gavazzi PB photoelectric sensor series, it combines an integrated amplifier, adjustable sensing range and robust plastic housing for dependable operation in demanding environments.
This sensor uses an NPN transistor output with complementary NO + NC switching, allowing flexible integration with PLC inputs, machine controllers and other industrial control equipment. Background suppression technology helps the sensor distinguish the intended target from objects or surfaces located behind it, improving detection reliability in automated systems.
With an adjustable sensing distance of up to 150 mm, a fast 1,000 Hz operating frequency and a 10–30 V DC supply, the PB15INPA-1 is well suited to high-speed presence, position and component detection. Its M12 connector supports straightforward installation and replacement in industrial machinery.

Reliable Photoelectric Detection for Industrial Automation
Diffuse reflective photoelectric sensors detect objects by transmitting light towards a target and monitoring the reflected light. Background suppression helps prevent distant surfaces from being mistaken for the intended target, providing more consistent detection where machinery, conveyors or structures are positioned behind the sensing point.
The Carlo Gavazzi PB series combines compact construction with integrated electronics and fast switching performance. The PB15INPA-1 is particularly suitable for automated machinery where reliable object presence or position detection and straightforward PLC integration are required.
Typical Applications
- Industrial conveyor object detection.
- Packaging and production machinery.
- Component presence and position monitoring.
- Assembly and handling equipment.
- Automated counting and detection systems.
- PLC-controlled machinery and factory automation.
