Linear’s 2-N-1 125 kHz Proximity Reader works with certain HID® AWID™ Farpointe® Data Pyramid Series protocols. 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.
