Data Sheet

NXT Series Proximity Readers

NXT-3R NXT-5RNXT-1R

Keri’s NXT Series Proximity Readers are designed to blend aesthetics, read range
performance, and small package size with an extremely thin profile into a product that is
priced significantly less than competing proximity readers. The readers are for use exclusively
with Keri’s revolutionary access control system based on the NXT Series of IP-based Controllers.
Encrypting identification data between the card and reader and supervising the reader from
the controller to check for failure provides the most secure reader solution available. With an
allowable cabling distance of 1,000 feet (300 m) from the controller the NXT Series of Readers
dramatically reduce cabling costs when compared to traditional 6- or 7-conductor reader
interfaces. The readers are compatible with all NXT Series Cards and Tags.

The NXT-1R Euro Mount Prox Reader offers the best combination of size and read range
available. Able to mount directly on a wall or to a European switch box, it offers a size and
profile not found in many other proximity readers.

The NXT-3R Mullion Reader, designed for mounting on metal window doorframes/mullions,
is one of the smallest proximity readers on the market yet offers exceptional read range.

The NXT-5R Wall Switch Reader can be mounted on a US single gang electrical box or flat
on a wall. Read range is up to 6” (15 cm) when mounted at least 1” (2.5 cm) off metal. Read
range will be slightly reduced if the reader is mounted using a metal electrical junction box
with only the thickness of the wall material separating the reader from the box.
