APPLICATION EXAMPLES

Restricting the use of machines and devices
BEFORE

Anyone can operate the machines.

Are you in charge of this device?

AFTER

Inadvertent operation andsetting changes are prevented,
reducing equipment
malfunctions and failures.
Mount the RFID reader on the operation
panel of a machine and register theworkers in the RFID reader. ID cards canthen be used to authenticate each worker.

Managing access to control rooms and inside safety fences
BEFOREDo not know if workers are left inside.

AFTER

By recording entry/exit logs,
workers can be prevented
from being trapped or left
behind in a work area.
Worker's names are linked to ID cards suchas employee ID cards, and that data is sent
when a card is read. Logs are recorded on
the host device to track entry/exit.

4

Is there anyone inside?

KW2D SERIESManage inspection history at production lines
BEFOREWork sheets were written by hand.

Are signatures still handwritten?

AFTER

The operator can record theirwork history by holding theemployee ID card over thereader.
The time and work details can be recordedby using the RFID reader together with atouch panel or PLC to ensure digital
traceability.

By connecting with devices such as touch panels and PLCs,
the RFID reader can be used for wide variety of applications.

Instructions
Applicable Wire

Crimping of Ferrules and Wiring

Power Supply Wiring• Choose an appropriate ferrule for the wire.
• Cut the wire carefully to get a flat end.
• Make sure that ferrule sleeve is completely filled by the conductor.
Depending on the cross section, the conductor should protrude
approx. 0 to 1mm from the ferrule sleeve.

• The KW2D Series RFID Reader has a push-in style terminal block.
• An inrush current of 25A or lower (when input is 24V DC) flows when
the power is turned on. Use a power supply with sufficient capacity.
• To prevent induction, keep the power line as short as possible, and as
far away as possible from motor lines.
• The following table shows the signals that correspond to the signal
codes. Be careful not to mistake the connections.
