2.45GHz Active tag introduction

1. The Appearance

2. Introduction

This tag is a 2.4GHz active tags, matched with MR3001A reader, it can be written to data and read out data, it

has 240 Bytes memory for users to store data. It uses two button lithium batteries to supply the source, and it has a

long lifetime and change battery is easily. At normal status, the tag is in sleep mode to save battery, when

MR3001A is working, it will wake up this tag, then the tag will send its ID to reader to finish the communication.

3. Applications and Features

●MR3820A active tag can be used in location system or personnel registry, and even conference attendance, etc.

●It should be matched with MR3001A reader to use in the real application

●Independent sending and receiving frequency, has a strong anti-interference ability

●The maximum indentify range can reach more than 80m(depend on the antenna of reader and the tag’s sending

power), ultra-wide frequency band design

●Multi-tag indentify at the same time (more than 50/s) while it can not be affected and limited by the amount of

tag within the antenna’s indentify range.

●Large memory for users to store data
