Banner Engineering Corporation SM51E-A LED Scanner

Banner Engineering's SM51E-A LED Scanner is a compact opposed-mode photoelectric sensor from the SM51 family, designed for non-safety automation tasks where a slim, flatpack footprint matters. Encased in a 1/2‑inch‑wide, die‑cast metal housing with totally encapsulated circuitry, it is built for harsh industrial environments and is compatible with 12–18 VDC supply via a shielded 4‑conductor cable up to 6 ft long. In an opposed‑mode configuration, the SM51E‑A forms a light-beam pair suitable for curtain‑of‑light sensing, edge detection, and code-reading applications on conveyors and machine lines. The family emphasizes rugged construction and straightforward interfacing to Banner logic modules such as MICRO‑AMP and MAXI‑AMP, with outputs that suit standard dc loads. A status indicator LED provides visual feedback when light is detected, helping technicians verify operation quickly. The flatpack design enables dense side‑by‑side mounting on 1/2‑inch centers, making it easy to build compact sensing curtains without adding bulk. Note: these sensors are intended for machine automation sensing and do not include self‑checking safety circuitry for personnel protection, so they should not be used as safety devices.
