Overview
What is inside the IDTS-IHZ16N 16-port UHF RFID reader
The IDTS-IHZ16N is the IDTS-IHZ4N with sixteen SMA antenna ports and is otherwise the same reader. Its housing is the IHZ4's aluminium, anti-shock case, here carrying sixteen SMA jacks marked ANT 1 to ANT 16. The RF side is an N704 third-generation reader module, and an interface board adds Ethernet, serial and I/O. It reads and writes ISO 18000-6C (EPC Gen2) and ISO 18000-6B tags.
Planning read points with sixteen antennas
Sixteen ports let one reader serve many read zones: a row of dock doors, every lane of a multi-lane gate, portals with antennas on several sides, or many shelf and cabinet zones in a stock room. Give each antenna its own zone and mount the reader centrally so the coaxial runs stay short. More than 30 dB of port-to-port isolation limits leakage between the reader's antenna ports; separating the zones themselves is down to antenna placement and output power.
Dense-reader mode helps where several readers share a hall. Range is the maker's test figure, so survey the site with your own tags before fixing the layout, and confirm each of the sixteen cables with antenna-connection detection before the trays are closed. Antennas for each zone are in our RFID antenna range.
One connection for sixteen zones
All sixteen zones report over a single Ethernet 10/100 link to the server, WMS or middleware on your LAN. RS-232 serves a nearby PC or controller, and RS-485 a PLC or serial network on a long cable run. Wiegand, for access or attendance controllers, comes only as an ordered customisation.
Two opto-isolated inputs and two relay outputs serve the whole layout, so plan which zones get them. A photo-eye, loop detector or door switch on an input lets your software start reading when something reaches that zone, and a relay can then light a lamp, sound a hooter or signal a barrier controller there. Relay ratings are in the specs table; bigger loads need a contactor.
IHZ16N or IHZ16: which to choose
IDTS-IHZ16N
N704 engine; Ethernet, RS-232 and RS-485; a pair of inputs and a pair of relays; Wiegand by customisation. Pick it when those links and two I/O pairs cover all sixteen zones.
IDTS-IHZ16
Impinj E710 engine in the same housing, also with sixteen antenna ports. Compared with the IHZ16N, it brings USB for bench set-up, Wiegand as standard, three inputs with three relays, and a higher listed read rate and read range. Choose the IDTS-IHZ16 when you need any of those.
For fewer zones, the IDTS-IHZ4N (four antenna ports) and the IDTS-IHZ8N (eight) are the same N704 reader.
Typical applications
- Warehouse dock doors
- Conveyor lines
- Production lines
- Library and file rooms
- Attendance and access gates
- Apparel stock rooms
- Vehicle and asset gates
