Precautions for Correct Use Precautions for Correct Use
• The cross section of the signal wires that can be connected to each soldering terminal must be
≤
0.3 mm

• Do not short circuit any terminals when soldering. Recommended is to cover every soldered
wire with an insulated tube.
• When using multi-conductor cables, separate the input- and output cables.

Terminal Block Unit
Besides direct connection as described above, it is also possible to make all the connections for the
external signals to screw-terminals. This is easier and less time-consuming than soldering the wires
to the external connector. For this purpose you should use a Terminal Block Unit. The following Ter-
minal Block Units are recommended for using together with the CJ1W-CT021 High-speed Counter
Unit:
• XW2B-40G4, which has 40 screw -terminals (M2.4) available
• XW2B-40G5, which has 40 screw -terminals (M3.5) available
These Terminal Block Units can be mounted to a DIN-rail or can be mounted using screws. The con-
nector on front of the Unit should be connected to a Terminal Block Unit through a standard (40 wire)
cable. For this purpose you can use the standard available cables with product-number XW2Z-xxxB.
The length of the cable is indicated by 'xxx' in centimetres. The following cables are available:
• XW2Z-050B (0.5 m)
• XW2Z-100B (1 m)
• XW2Z-150B (1.5 m)
• XW2Z-200B (2 m)
• XW2Z-300B (3 m)
• XW2Z-500B (5 m)
