New Product XW4H/XW4K/XW4L PCB Terminal Blocks: Push-in SMT Terminals with 2.54mm Pitch Push-in Terminals to Easily Complete Connections. PCB Terminal Blocks with 2.54mm Pitch. • Push-in connection method allows repeated repairs. • Hold-down structure for strength on PCBs. • Active lock mechanism for superior vibration and shock resistance. • Both vertical and horizontal models available. • Suction cover included to enable automatic mounting. • Can be mounted to the back surfaces of PCBs. Features • Just insert solid wires or ferrules to complete wiring. With Stranded wires, all you need is a flat-blade screwdriver. Solid wire or ferrule Stranded wires Connection completed! Insert the screwdriver into the release hole and then insert the stranded wires. XW4Z-00A • Hold-downs are provided on both ends to achieve robust mounting by increasing solder mounting strength. The hold-downs are circled in red. • An active lock mechanism prevents the Terminal Blocks from coming off to provide superior vibration and shock resistance.

Accessories Special Screwdriver XW4Z-00A Models Minimum ordering quantity (pieces) XW4Z-00A 1 Safety Precautions Precautions for Correct Use ● Soldering Conditions ● Metal Mask Thickness for Cream Solder Printing • Recommended Reflow Conditions Maximum temperature: 255°C Time: Within 20 s 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. (°C) Peak temperature 255 Soldering temperature 240 Preheating temperature 150 ● Pin Deformation (s) Preheating time: Within 60 to 120 s Soldering time: Within 20 to 40 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. 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. 7 ● Terminal Block Connection Method XW4H, XW4L ● 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 and Specifications for the wire stripping length. 6±1mm (3) Do not presolder the ends of the wires. Doing so will prevent correct connections. ● Connection Methods Using Ferrules or Solid Wire 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. Removal Method (Unit: mm) Release holes A A 0.4 2 dia. Terminal insertion holes 9 Just press the ferrule all the way in. Insert the screwdriver into the release hole and pull out the ferrule. 2 Using Stranded Wires 40 Using Stranded Wires To insert a stranded wire, insert a screwdriver into the release hole and then insert the wire. To remove a stranded wire, insert a screwdriver into the release hole and then pull out the wire. Note: Do not apply excessive force to the Terminal Block when you insert the tool. The Terminal Block may be damaged. • Application examples provided in this document are for reference only.
