The Banner Engineering VALU-BEAM SMI91ESRQD emitter provides a 3 m through-beam light source for automation sensing, powered from 10–30 V DC and featuring a mini-style integral quick-disconnect (QD). As the emitter half of a VALU-BEAM pair, it outputs no electrical signal itself and is intended to be paired with a matching receiver to detect beam interruptions. This SMI91ESRQD variant belongs to Banner's VALU-BEAM family and is designed for compact, field-installable installations in industrial environments, offering a 3 m sensing range and 10–30 V DC input.
