Slim Connector-Terminal Block Conversion Units
XW2D
CSM_XW2D_DS_E_2_1
New Slim Connector-Terminal Block
Conversion Units.
• Mounting area reduced by 35% (in comparison with
40-pole XW2B Units) to contribute to downsizing
control panels and automatic equipment.
• Fallout prevention for terminal screws.
• Round or forked crimp terminals can be used.
• Mount to DIN Track or via screws.
Unique DIN Track lock can maintain open status
during DIN Track attachment and removal.
• Terminal cover can be locked open.
• Screw terminals are arranged by color in groups
of five to simplify counting terminal numbers.

Safety Precautions
Precautions for Correct Use
● Wiring
● Mounting Units to and Removing Units from DIN Track
• Always turn OFF the power supply before wiring.
Otherwise, cables or other conductors can short the terminals and cause the Unit to fail.
• Do not connect or disconnect Connectors with the power
turned ON. Otherwise, it may cause malfunctions.
• XW2D Connector-Terminal Block Conversion Units can be
mounted side-to-side on DIN Track.
• Secure both ends of the XW2D with End Plates.
• When removing the Unit from a DIN Track, insert a flat-head
screwdriver into the slider and pull the lock out.
● Wiring Terminal Blocks
Using Crimp Terminals
(With a Terminal Block with M3 Screws)
Round crimp terminals
Forked crimp terminals
3.2 mm dia.

Applicable crimp terminals
Applicable wires
Round crimp terminals

(0.30 to 1.25 mm2)
● Terminal Screw Tightening Torque
● Handling M3 Screw and Round Terminals
Raise the M3 screw with a Phillips screwdriver as shown in diagram (1) and slide the screw toward you to keep the space
open. Follow the steps in diagrams (1) and (2) below when using round crimp terminals.
Use a tightening torque of 0.7 N·m when connecting wires or
crimp terminals to the terminal block.
