Dimensions in mm L = (pole no. x pin spacing) + 1.5 mm . PCB terminal block, 254 Series, solder pin dimensions 0.5 x 0.75 mm This PCB terminal block (item number 254-458) is designed to connect conductors quickly and easily. It is perfect for custom installations with different mounting types. Ensure that the strip lengths are between 10 and 12 mm when connecting conductors to this PCB terminal block. This product fea­ tures one conductor terminal and utilizes PUSH WIRE®. Our PUSH WIRE® connection offers a simple and reliable solution for connecting solid conduc­ tors. The item's dimensions are (41.5 x 19.7 x 13.5) mm (width x height x depth). This PCB terminal block is suitable for conductor cross sections ranging from 0.5 mm² to 2.5 mm². The contact surface is coated with tin. This PCB terminal block is operated with an operating tool. THT is used to solder the PCB terminal block. Insert the conductor into the board at an angle of 45°.. Page 1/6 Version 20.03.2026 Continued on next page **==> picture [557 x 819] intentionally omitted <==** **----- Start of picture text -----**
