Part numbers
From the manufacturer's datasheet for LDF+ RS485 BACnet.
Overview
The LDF+ measures brightness in rooms and workspaces for control of lighting and blinds. The sensor is matched to the response of the human eye. The straight prism suits interior lighting and the diagonal prism suits outdoor lighting. The remote sensor connects to the USE-M housing with a standard RJ45 patch cable, 1.5 m on these versions, so the housing can be fitted somewhere accessible. The dual versions take two sensors and can give the average, minimum or maximum of both, set in the USEapp. It reports over RS485 BACnet MS/TP.
