pb15inpa – photo bs pl npn no+nc cab
Carlo Gavazzi PB15INPA is a diffuse reflective photoelectric sensor with background suppression, an adjustable 150 mm sensing distance, NPN NO + NC outputs and a 2 m cable for industrial automation applications.
Why Choose the Carlo Gavazzi PB15INPA Photoelectric Sensor?
The Carlo Gavazzi PB15INPA is a compact and reliable diffuse reflective photoelectric sensor with background suppression designed for precise object detection in industrial machinery and automation systems. As part of the Carlo Gavazzi PB photoelectric sensor series, it combines an integrated amplifier, adjustable sensing range and robust flat plastic housing for dependable operation in demanding applications.
The PB15INPA uses an NPN transistor output with complementary NO + NC switching, providing flexible integration with PLC inputs, machine controllers and industrial control systems. Its background-suppression sensing principle helps distinguish the required target from surfaces or objects positioned behind it, improving detection reliability in automated production environments.
With an adjustable sensing distance of up to 150 mm, an operating frequency of 1,000 Hz and a 10–30 V DC supply, the PB15INPA is suitable for fast presence, position and component detection. This cable-connected version is supplied with a 2 m cable for straightforward connection within machinery and control installations.

Reliable Photoelectric Detection for Industrial Machinery
Diffuse reflective photoelectric sensors detect objects by transmitting light towards a target and evaluating the returned light. Background suppression enables the sensor to differentiate the intended target from more distant surfaces, helping provide consistent object detection where conveyors, machinery or structural components are positioned behind the sensing point.
The Carlo Gavazzi PB series combines compact flat-housing construction with integrated electronics and fast switching performance. The PB15INPA is particularly suitable for automated machinery requiring dependable presence or position detection, while its complementary NPN outputs provide flexibility when interfacing with industrial control equipment.
Typical Applications
- Industrial conveyor object detection.
- Packaging and production machinery.
- Component presence and position monitoring.
- Assembly and material handling equipment.
- Automated counting and detection systems.
- PLC-controlled machinery and factory automation.
