PCB terminal block, 745 Series, solder pin dimensions 0.8 x 1.2 mm This PCB terminal block (item number 745-3104) streamlines wire connections, making them both quick and easy. It is a universal connector that can be used practically anywhere, for example, as a pluggable PCB connector, panel feedthrough header, connector for rail-mount terminal blocks, or a floating connector for different mounting methods. Ensure that the strip lengths are between 8 and 9 mm when connecting conductors to this PCB terminal block. This product incorporates one conductor terminal and utilizes CAGE CLAMP®. Our renowned universal connection known as CAGE CLAMP® is Page 1/6 Version 21.03.2026 Continued on next page
# Data Sheet | Item Number: 745-3104 https://www.wago.com/745-3104 the industry standard when it comes to connection technology and electrical interconnections. The dimensions are (21.5 x 23 x 19.4) mm (width x height x depth). This PCB terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 4 mm². The contact surface is coated with tin. This PCB terminal block is operated with an operating tool. The PCB terminal block is designed for THT soldering. Insert the conductor into the board at a 45° angle..
