Banner Engineering SMI91ESRQD Photoelectric Sensor

The Banner Engineering SMI91ESRQD VALU‑BEAM emitter is a compact mini‑style photoelectric source that forms the transmitting half of Banner’s VALU‑BEAM sensing pair. It provides a 3 m sensing range and operates from a 10–30 V DC supply; it has no output channel because it is an emitter, not a receiver. The unit features a Mini‑style Integral Quick‑Disconnect (QD) connector for fast, tool‑free wiring and mounting. Banner lists this model as obsolete and directs customers to consider a suitable replacement, reflecting its status in the current VALU‑BEAM lineup. The SMI91ESRQD is not intrinsically safe, and its documentation includes certifications such as FM/ATEX references, indicating compliance considerations when paired with compatible receivers in appropriate environments. When used with a matching VALU‑BEAM receiver, the emitter projects an infrared beam across the 3 m gap, enabling presence/absence sensing on conveyors, packaging lines, and automation equipment where space is limited and rapid alignment is beneficial.
