The EMX IRB-325 is a thru beam infrared photoeye pair designed as an external entrapment protection device Type B1 for automatic gates and doors. It provides a clear beam break signal to the operator so the system can react when the beam is obstructed. This model is specified for up to 65 ft line of sight range and is UL325 2018 compliant with operators that require normally closed monitoring. It is intended for modern safety focused installations where monitored photoeyes are required by the operator or by site requirements. Power input supports 12 to 24 VDC AC, and the receiver provides Form C relay contacts to match common gate and door operator inputs. Sensitivity can be set on the unit to help dial in performance for different site distances and conditions. The housings are NEMA 4X rated for outdoor exposure, and the steel hoods help protect against environmental exposure and accidental contact around active equipment areas. Install and wire per EMX instructions and the operator manufacturer requirements for your system.
