Wenglor P1NH302 Reflex Sensor Background Suppression

Wenglor P1NH302 Reflex Sensor Background Suppression offers an ultra-compact and high-precision sensing solution that utilizes laser light technology and the triangulation principle to detect objects with surgical accuracy. Designed to excel in confined industrial spaces, the P1NH302 ensures a constant switching distance regardless of the target’s color, texture, or shape, effectively eliminating interference from shiny or complex backgrounds. By integrating a sophisticated IO-Link interface, this sensor not only allows for the flexible configuration of PNP/NPN outputs but also provides critical diagnostic data, making it a cornerstone for reliability in high-speed, automated production lines.

Application Of Wenglor P1NH302 Reflex Sensor Background Suppression

Packaging Detection: Identifies multi-colored or patterned boxes on conveyors without being “tricked” by dark logos or bright graphics.
Presence Verification: Confirms the correct placement of components in assembly lines by measuring height differences.
Logistics Sorting: Reliably detects the leading edges of packages, including those made of rough or recycled cardboard.
Tray Fill Monitoring: Checks for the presence of products within containers while ignoring the container’s bottom.
High-Speed Counting: Tracks up to 1,000 items per second, ideal for rapid-fire production and bottling lines.
Dynamic Background Suppression: Ignores moving robotic arms or metallic machinery parts located behind the target.
Predictive Maintenance: Uses IO-Link to alert operators if the lens is dirty, preventing unexpected downtime.
