PCB terminal block, 745 Series, solder pin dimensions 0.8 x 1.2 mm Our PCB terminal block (item number 745-103) ensures effortless electrical installations. It is perfect for custom installations with different mounting types. 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 reliable and maintenance-free CAGE CLAMP® connection makes it easy to connect all conductor types without having to prepare the conductor. For example, you don't need to crimp ferrules. The dimensions are (16.5 x 23 x 22.9) mm (width x height x depth). This PCB terminal block is suitable 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 into the board at an angle of 45°..
