Information About E3S-AR11
The E3S-AR11 is part of the Omron E3S-A series of square-body photoelectric sensors built for industrial environments. It uses a polarized retro-reflective sensing method with a red LED light source and supports detection when paired with a compatible reflector. The housing is constructed from durable polybutylene terephthalate (PBT) and rated IP67 for protection against dust and water ingress. Designed for stable operation, it includes a two-turn endless sensitivity adjustment and integrated status indicators for installation and monitoring.
