Information About SM31RLQDP
The SM31RLQDP is part of the Banner Engineering MINI-BEAM® Series and functions specifically as a through-beam receiver. It must be paired with a compatible MINI-BEAM emitter to complete an opposed sensing system. The sensor is housed in a compact rectangular thermoplastic enclosure with IP67 environmental protection and an 18 mm threaded mounting design. Integrated LED indicators provide power and output status, while the DC-powered electronics support light/dark operate configuration.
