Overview
The Banner SM312DMHSM5VQD is a miniature photoelectric sensor engineered for presence and absence detection in industrial automation and machine control applications. Operating on 5VDC, this self-contained diffuse-mode sensor combines compact form factor with robust performance. The SM312 series delivers consistent sensing across registration, conveyor, and packaging applications where space and reliability are critical.
