Description
PCB terminal block, 744 Series, orangeOur PCB terminal block (item number 744-303/000-012) is the perfect way to connect conductors quickly and securely. It is a universal connector that can be used almost anywhere, e.g., as a pluggable PCB connector, panel feedthrough header, connector for rail-mount terminal blocks, or a floating connector for different mounting methods. Conductors should only be connected to this PCB terminal block if their strip length is between 8 and 9 mm . This product features one conductor terminal and utilizes PUSH WIRE®. Our PUSH WIRE® connection offers a quick and easy method for connecting solid conductors. The item’s dimensions are (11.4 x 10.1 x 12.5) mm (width x height x depth). This PCB terminal block is suitable for conductor cross sections ranging from 0.5 mm² to 1.5 mm².Tin is used for coating the contact surfaces. An operating tool is used to operate this PCB terminal block. The PCB terminal block is designed for THT soldering. Insert the conductor into the board at an angle of 0°..
