Installation method  Fixing screws in four locations, with two locations fixed with reader/writer mounting screws
*1 V680S-A63/A64/A66 includes four mounting holes for fixing.
When mounting with a reader/writer already installed, or when no mounting holes for a new connector cover are available 
other than the reader/writer mounting holes, the connector cover can be fixed in two locations with the same mounting holes 
used for the reader/writer. 
This makes it possible to install the connector cover without the need for additional mounting holes. 
When tightening the products together in two locations, use the longer screw for the thicker part of the connector cover 
being tightened (thickness: 11.2 mm for V680S-A63, 6 mm for 680S-A64/A66).

Section 1 Product Specifications 
 High-temperature Applications (V680-D1KP58HTN)  
 Data Retention 
• Due to the characteristics of EEPROM, any data that is written to an RF Tag may be lost if it is used 
in a high-temperature environment that exceeds 125° C for a total of more than 10 hours. Always 
reset the data holding time before a total of 10 hours is reached.
• Communications between the Reader/Writer and RF Tags may fail in high-temperature environments 
of 85° C or higher. Do not perform communications between the Reader/Writer and RF Tag in a high-
temperature environment of 85° C or higher.
• Due to the characteristics of EEPROM, the UID (RF Tag ID code) may be lost if an RF Tag is used in 
a high-temperature environment that exceeds 125° C. Do not use commands that use the UID in 
high-temperature environments that exceed 125°C. 
•Do not use the ID READ command. 
•You cannot use FIFO trigger communications.

The V680-D1KP54T RF Tag can be placed in the Attachment in either direction. 
The direction does not affect operation.
Section 4 Installation 
Do not repeatedly place the RF Tag in the Attachment and remove it from the Attachment. If you do so, the RF Tag will 
become loose or the Attachment will be damaged.
If you must remove an RF Tag from the Attachment, insert a flat-blade screwdriver in the gap under the RF Tag. Do not 
try to remove it with your bare hands. Doing so may result in injury.
2. Mount the Attachment with M3 screws. 
Tighten the screws to a suitable torque.
Tightening torque: 0.3 to 0.5 N·m
 Installation with Adhesive 
Select an adhesive that is suitable for the materials. Use the correct application method and amount. 
Always confirm that the RF Tag is securely attached before you use it.
The RF Tags are made from PPS resin. We recommend epoxy adhesives to mount them on metal or 
hard plastic.
The epoxy adhesives that are listed in the following table are recommended for the given temperature 
ranges.
