Why Choose the Carlo Gavazzi PA15INPA-1 Photoelectric Sensor?

The Carlo Gavazzi PA15INPA-1 is a compact diffuse-reflective photoelectric sensor with background suppression designed for accurate object detection in industrial automation. Its adjustable sensing distance of 50–150 mm allows the sensor to distinguish a target from objects or surfaces positioned behind it, helping provide reliable detection in demanding machinery and material-handling applications.

The PA15INPA-1 operates from a 10–30 V DC supply and provides an NPN make-and-break output, giving both NO and NC switching functions. A fast operating frequency of up to 1000 Hz makes the sensor suitable for rapid production processes, while modulated 880 nm infrared light supports dependable optical sensing.

Built into a durable aluminium housing measuring approximately 36 × 18 × 60 mm, the PA15INPA-1 combines compact dimensions with IP67 ingress protection. The M12 plug connection, yellow output LED and built-in protection against reverse polarity, short circuits and electrical transients simplify installation and support reliable long-term operation.

Reliable Background-Suppression Object Detection

Background-suppression photoelectric sensing is useful where the sensor must detect a target while ignoring surfaces located beyond the selected sensing point. Rather than relying solely on the amount of reflected light, the PA15INPA-1 provides an adjustable detection range that helps separate the intended object from the background, supporting consistent detection in automated machinery.

The Carlo Gavazzi PA15INPA-1 combines this sensing principle with high-speed operation, NPN NO and NC switching, an industrial DC supply range and a rugged aluminium enclosure. Its compact dimensions and M12 connection make it a practical choice for machine builders and automation engineers requiring accurate, easily integrated optical sensing.

Typical Applications

• Packaging and processing machinery.
• Conveyor object and product detection.
• Automated assembly equipment.
• Component presence and position monitoring.
• Material handling and sorting systems.
• Production counting and detection systems.
• Applications requiring suppression of a nearby background.
• General industrial automation and machine control.
