E3S-AR11 | Omron E3S-A Retro-Reflective Photoelectric Sensor 2m NPN
Omron · Sensors & Instrumentation
Description The Omron E3S-AR11 is a retro-reflective photoelectric sensor designed for object detection up to 2 meters in industrial automation systems. It operates on 10 to 30 VDC and provides an NPN open-collector output with selectable Light-ON or Dark-ON modes. The sensor is equipped with a 2 m pre-wired cable for direct installation in control panels and production equipment. Technical Specifications Condition New/Never Used Surplus Brand Omron Category Sensors & Switches Part Number E3S-AR11 Subcategory Photoelectric Series E3S-A Sensing Method Polarized Retro-Reflective Sensing Distance 0.1 m to 2 m Light Source Red LED (660 nm) Supply Voltage 10 to 30 VDC Current Consumption 30 mA max. Output Type NPN Open Collector Switching Current 100 mA max. Response Time 0.5 ms max. Connection Method Pre-Wired Cable (2 m) Ingress Protection IP67, NEMA 4X Operating Temperature -25°C to +55°C Body Material Polybutylene Terephthalate (PBT) Weight 6 oz Information About E3S-AR11 The E3S-AR11 is part of the Omron E3S-A series of square-body photoelectric sensors built for industrial environments. It uses a polarized retro-reflective sensing method with a red LED light source and supports detection when paired with a compatible reflector. The housing is constructed from durable polybutylene terephthalate (PBT) and rated IP67 for protection against dust and water ingress. Designed for stable operation, it includes a two-turn endless sensitivity adjustment and integrated status indicators for installation and monitoring. Key Features: Retro-Reflective Sensing: Detects objects from 0.1 m to 2 m using a reflector. NPN Open-Collector Output: Supports up to 30 VDC and 100 mA switching current. Selectable Operation Mode: Configurable for Light-ON or Dark-ON operation. 10–30 VDC Supply Voltage: Wide operating voltage range for DC systems. Fast Response Time: 0.5 ms maximum operate or reset time. IP67 Protection Rating: Resistant to dust and water for industrial use. Two-Turn Sensitivity Adjustment: Fine tuning with visual indicator. Pre-Wired 2 m Cable: Direct connection for simplified installation. The E3S-AR11 delivers the reliability and precision required for industrial photoelectric detection and object sensing applications.
