# Dimensions in mm # L = (pole no. – 1) x pin spacing + 5 mmL1 = L + 1.5 mm ≙ version without mounting flange . # PCB terminal block, 745 Series, operating tool # Easily, quickly and safely connect conductors with this PCB terminal block (item number 745-104). It is a universal connector that can be used almost 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 prod­ uct incorporates one conductor terminal and utilizes CAGE CLAMP®. Our CAGE CLAMP® connection offers a proven and maintenance-free way to con­ nect all types of conductors. You do not need to prepare the conductor in any way, such as crimping ferrules. Dimensions: (21.5 x 23 x 22.9) mm (width x height x depth). Depending on the conductor type, this PCB terminal block is ideal for conductor cross sections ranging from 0.08 mm² to 4 mm². # Tin is used for coating the contact surfaces. This PCB terminal block is operated with an operating tool. The PCB terminal block is designed for THT sol­ dering. The conductor is designed to be inserted at a 45° angle..
