Overview
The Banner Engineering SM312DQD is an industry-standard mini-beam photoelectric sensor built for reliable diffuse-mode detection in manufacturing and automation environments. With a 380mm sensing range and dual NPN/PNP output capability, this sensor supports both light-operate and dark-operate configuration via switch selection. The integral 4-pin M12 quick-disconnect connector simplifies field installation and replacement.
Key Features
- Diffuse sensing mode — detects objects without requiring a reflector or opposed setup
- Bipolar output — configurable NPN or PNP transistor output for flexible PLC integration
- Light/Dark operation — switch-selectable operating mode for detect-on-presence or detect-on-absence
- M12 quick-disconnect — integral 4-pin QD connector for fast plug-and-play deployment
- Infrared LED source — robust sensing immune to ambient light interference
- Rugged construction — PBT thermoplastic housing, acrylic lenses, stainless steel hardware, IP67 rated
- Potentiometer adjustment — field-tunable sensitivity for application-specific optimization
