"MF-T Reflex and MF-L Reflex are muting units with integrated retro-reflective photocells in the same profile type as the Focus Light Curtain\/Grid. No additional sensors are required because the muting units contain the required components. The Reflex series simplifies the set up of muting sensors, as only 1 side requires a cable connection. The reflective side is a polarized reflector bar. MF-T Reflex and MF-L Reflex are connected directly to the Focus Receiver with M12 connectors.","MF-T Reflex (Option 3)","MF-T Reflex contains four transmitters\/receivers and a separate reflector unit. Range 6m. Used in the muting mode for transport of material into and\/or out of hazardous areas. For other functions refer to Option 1. This unit, together with light beam F4-K1C-500 provides electrical connections on only one side.","MF-L Reflex (Option 4)","MF-L Reflex contains two transmitters\/receivers and a separate reflector unit. Range 6m. Used in the muting mode for transport of material into and\/or out of hazardous areas. For other functions refer to Option 2. This unit, together with light beam F4-K1C-500 provides electrical connections on only one side.","Note: MF-L Reflex unit is primarily intended for material transport \"out\" of a working area. The standard Focus Light Curtain\/Grid delivered does not function together with the MF-L Reflex version. The Focus Light Curtain\/Grid L version needs to be ordered separately, as well as the MF-L unit.","Note: The muting sensors A and B must be placed so that the sensor A is always activated at least 30 ms before sensor B.D: indicates the minimum length of the material that is to actuate the muting sensors that must be maintained during the passage through the light curtain\/grid. d2: indicates the measurement between the two pre-assembled muting sensors within the MF-T Reflex andMF-L Reflex (= 150mm)."
