EM300

Name: EM300
Brand: Identix
SKU: ID-EM300

Compact four-port RAIN RFID reader powered over Ethernet

Part numberID-EM300

The EM300 drives four external antennas at once from a 150 x 90 mm box, each with its own radio settings. It runs on PoE or USB at up to +30 dBm, and its keyboard emulation drops into software built for barcode scanners.

Choose it when

You need to cover a door, a counter or a short line with up to four antennas from one small box. It runs on PoE or USB, and each antenna has its own radio settings.

Outdoors? Choose the EM300H. Many tags at once or heavy conveyor traffic? Choose the EZ500 or EZ700.

Questions we hear

What do I buy with it?

Up to four antennas and their RF cables, chosen for your read zone. Identix does not supply tags. ExitView already includes an EM300, so you buy no reader there.

Can I use more than four antennas?

Yes. A CATENA turns one port into eight antennas, up to 32 on a four-port reader. An RF splitter turns one port into two, up to 8 antennas.
