Linear’s 2-N-1 125 kHz Proximity Reader works with certain HID, AWID & Farpointe and SecuraKey protocols (depending upon the part number). The proximity reader is designed to fulfill two different mounting requirements – without needing any additional hardware! The 2-N-1 can be installed as either a mullion-mount reader or, when paired with the provided adapter plate, turns the reader into a single-gang electrical box style reader. Customers get a clean, low profile for both mullion and single-gang installations ready to install right out of the box for either configuration. Linear’s cards and tags do not contain batteries, requiring no maintenance. Reduce your stock and never be on the job again without the right model reader.
