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 RF Tags.
EEPROM Memory
EEPROM (non-volatile memory) is used for RF 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 RF Tags. This method maintains superior communications reliability even where prob-
lems such as noise occur.
1,000byte of Memory
RF Tags have 1,000byte of memory. In addition to the ID data required on-site, data such as model
numbers and inspection information can be input.
100,000 Data Rewrites at Normal Temperatures
When the RF Tag is used at temperatures of up to 25
°
C, each block of EEPROM data can be rewritten
up to 100,000 times (in units of single block, 8-bytes).
Superior Environmental Resistance and High Reliability
Antennas and RF Tags now have greater environmental resistance and are not affected by vibration,
oil, or water.
