Product Overview
Features
The V680-series RFID System actively supports many different types of system, such as distributed-control
systems and many-product, small-lot production systems, with non-contact data communications using
electromagnetic induction.
 Non-contact Data Communications
The V680 Series uses electromagnetic induction to enable non-contact, bi-directional data communi-
cations between Antennas and Tags.
 EEPROM Memory
EEPROM (non-volatile memory) is used for Tag memory. No battery is required, so there is no need to
be concerned about battery service life.
 CRC Used for Transmission Error Detection
A bi-directional 16-bit CRC (Cyclic Redundancy Check) has been added as the error detection method
for wire transmissions between ID Controllers and Antennas, and for wireless transmissions between
Antennas and Tags. This method maintains superior communications reliability even where problems
such as noise occur.
 One Kilobyte of Memory
Tags have one kilobyte of memory. In addition to the ID data required on-site, data such as model num-
bers and inspection information can be input.
 Long Service Life of 100,000 Data Rewrites at Normal Temperatures
When the Tag is used at temperatures of up to 25°C, each bit of EEPROM data can be rewritten up to
100,000 times.
 Superior Environmental Resistance and High Reliability
Antennas and Tags now have greater environmental resistance and are not affected by vibration, oil, or
water.
