Banner Engineering SMA91EQDH AC DC Scanner Module

The Banner Engineering SM91EQDH is a through-beam VALU-BEAM scanner block used for long-range object detection in industrial automation. It is a DC scanner in the VALU-BEAM 912 family that accepts universal power from 10 to 250 V AC or DC via a 4-pin M12 connector, and it employs an infrared emitter at 880 nm with a sensing range up to 60 m. The rugged housing is designed for mounting with standard limit-switch hole spacing, making it straightforward to retrofit on conveyors, machinery, or packaging lines. When the beam is interrupted, the receiver provides a digital indication suitable for direct integration with control logic, alarms, or counting schemes in manufacturing environments. Typical applications include non-contact part detection on long conveyor runs, end-of-line sensing, and process control tasks where reliable beam interruption detection is required. This DC-scanner variant—SMA91EQDH/SM91EQDH—belongs to Banner’s VALU-BEAM family and is valued for compact form factor and compatibility with Banner emitters to form complete through-beam sensing systems.
