This model employs retroreflective sensing, using a reflector to detect targets within a 2-meter range, minimizing alignment effort and reducing false detections. The sensor integrates a two-turn endless sensitivity adjuster with an indicator LED, allowing precise configuration and visual feedback during setup. Its fast 500 µs response time enables accurate detection of moving objects in conveyor, packaging, and material handling systems. Encased in a rugged housing with IP67 and NEMA 4X ingress protection, the E3S-AR91 withstands dust, moisture, and cleaning environments, ensuring long service life. Key Features: Retroreflective Detection: Simplifies installation with a single device and reflector setup. Long Sensing Range: Detects objects reliably up to 2 meters away. Selectable Output Mode: PNP output configurable for Light-ON or Dark-ON operation. Fast Response Time: 500 µs for high-speed detection in automated systems. Red LED Light Source: Visible 700 nm beam simplifies sensor alignment. Two-Turn Sensitivity Adjuster: Allows precise manual tuning with visual feedback. Rugged Protection: IP67 and NEMA 4X ratings ensure resistance to water, dust, and washdown conditions. Wide Operating Voltage Range: Operates from 10 to 30 VDC for flexible system integration. The E3S-AR91 delivers the reliability and precision required for high-speed object detection and positioning in industrial automation and packaging applications.
