Overview
The Banner S18AW3FF50Q1 is a fixed-field infrared photoelectric sensor from the S18 series, engineered for robust performance in demanding industrial automation applications. This barrel-mount sensor combines epoxy encapsulation with fixed-field detection optics to deliver consistent object sensing without alignment adjustments. Rated for IP67 and IP69K protection, it withstands splashing, dust ingress, and high-pressure wash-down environments common in food processing, beverage bottling, and manufacturing facilities.
Key Features
- Fixed-Field Detection: 50 mm sensing range with fixed optics; no field adjustment required
- Environmental Protection: IP67/IP69K sealed housing withstands washdown and harsh conditions
- Solid-State Output: SPST AC solid-state switch rated 300 mA continuous, light-operate configuration
- AC Powered: 20–250 V AC input; operates worldwide without DC/AC supply conversion
- Quick-Disconnect: 4-pin 1/2″-20 UNF micro-integral quick-disconnect connector for fast replacement
- Infrared Sensing: 880 nm modulated infrared beam for reliable object detection
