Wenglor P1NE201 Through Beam Sensor

Wenglor P1NE201 Through Beam Sensor serves as a high-performance optical receiver designed for extreme reliability, utilizing a visible red light barrier to detect objects across distances of up to 20 meters. Unlike reflex-style sensors, the P1NE201 operates by identifying the direct interruption of light between an emitter and receiver, making it completely immune to the target’s color, gloss, or transparency. Enhanced with an IO-Link 1.1 interface, this sensor not only delivers high-speed switching for rapid production lines but also provides smart diagnostic data, ensuring seamless integration into modern Industry 4.0 environments.

Application of Wenglor P1NE201 Through Beam Sensor

Large-Area Monitoring: Detecting objects across wide spans or entrances up to 20 meters.
Transparent Detection: Reliably sensing clear glass, plastic bottles, or thin films.
Dark Target Sensing: Identifying jet-black or light-absorbing materials with 100% accuracy.
Protrusion Control: Checking for misaligned parts or overhangs on pallets in automated warehouses.
Web-Break Monitoring: Detecting tears in continuous rolls of paper, foil, or textiles.
Dust & Mist Resistance: High-intensity beam penetrates airborne dust and steam better than reflex sensors.
High-Speed Counting: Accurate counting of fast-moving items with a 0.5 ms response time.
Predictive Maintenance: Using IO-Link to monitor signal strength and signal when lenses need cleaning.
