Power Supply Wiring

• 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.

Crimping of Ferrules and 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.

0～1mm

• When crimping, refer to the instructions of the crimping tool.

Max. 1.48mm

Max. 2.1mm

Faults which can occur during crimping:

• Cracks along the sides and die impressions

• Splitting of the ferrules

• Asymmetrical crimping shape

• Extreme burrs formed along the sides

• Ferrule not filled by conductor

• Single conductors pushed back by protruding from the insulated cover

• Single conductors squeezed off

• Insulation cover damaged by the crimping jaw

• Conductor insulation not pushed into the insulated cover

• Ferrule bent longitudinally after crimping
