●Soldering Conditions

•Recommended Reflow Conditions
Maximum temperature: 255°C
Time: Within 20 s

These conditions depend on the type of solder, the manufacturer, the amount of solder, the size of the circuit board, and the other mounting materials. You must check and select the actual conditions yourself.

●Metal Mask Thickness for Cream SolderPrinting

We recommend a metal mask thickness of 0.12 to 0.15 mm for cream solder printing. These conditions, however, depend on the type of solder, the manufacturer, the amount of solder, the size of the circuit board, and the other mounting materials. You must check and select the actual conditions.

●Pin Deformation

The pins will deform if you subject them to an excessive load. Deformed pins will reduce solderability when the Connectors are mounted. Do not drop the Connectors or handle them roughly. Do not connect or disconnect Connectors that are not mounted to a circuit board. Doing so may deform the pins.


●Wiring Terminal Blocks

Directly Connecting Wires
(1) Use wires with conductors that are within the connectible wire range.
(2) Prepare the ends of the wires as shown below.
Refer to Ratings / Characteristics for the wire stripping length.

(3) Do not presolder the ends of the wires. Doing so will prevent correct connections.

●Connection Methods

Using Ferrules or Solid Wire

Connection Method Removal Method



Using Stranded Wires

Using Stranded Wires


Note: Do not apply excessive force to the Terminal Block when you insert the tool. The Terminal Block may be damaged.

●Terminal Block Connection Method

Using Crimp Terminals

(1) Use ferrules or tab terminals.
However, the Terminal Blocks are small, so sufficiently confirm the following before you use them.

(2) Insulation between Crimp Terminals If you use naked crimp terminals, there will be no finger protection.
Also, there will be limited clearance and creepage distances between adjacent terminals, so use crimp terminals with care.

●Special Screwdriver for Terminal Blocks

Use the XW4Z-00A Special Screwdriver to connect the Terminal Blocks.
You can also use any screwdriver with the following dimensions.
If you use any screwdriver other than the Special Screwdriver or one with the following dimensions, the Terminal Block may be damaged.
