EM300H

IP67 outdoor RAIN RFID reader with built-in 7 dBi antenna

Part numberID-EM300H
Impinj GEN2X

The EM300H takes the EM300 outdoors: IP67 housing, a built-in dual linear 7 dBi antenna and two extra SMA ports. An 8 MB buffer keeps reads during network outages and syncs them when the link returns.

Choose it when

You read vehicles or goods outdoors, at a gatehouse or a yard entrance, where rain and dust reach the reader. IP67 housing, 7 dBi antenna already inside.

Indoors, with four external antennas? The EM300 has four antenna ports. The EM300H has two.

Questions we hear

What happens if the network goes down?

An 8 MB buffer keeps the reads. When the link returns, the reader syncs them.

How do I power and connect it?

PoE (802.3af/at) or USB for power. Ethernet, USB, Wi-Fi and Bluetooth for data. Two SMA ports take external antennas.
