# PCB terminal block, 256 Series, with 5 mm pin spacing 

# Our PCB terminal block (item number 256-405) is the perfect way to connect conductors quickly and securely. It is a universal connector that can be used practi­ cally anywhere, for example, as a pluggable PCB connector, panel feedthrough header, connector for rail-mount terminal blocks, or a floating connector for dif­ ferent mounting methods. Conductors should only be connected to this PCB terminal block if their strip length is between 5 and 6 mm . Featuring one conductor terminal along with CAGE CLAMP®, this connector outperforms the competition. Our CAGE CLAMP® connection provides a secure and maintenance-free way to connect all types of conductors. You do not need to prepare the conductor in any way, such as crimping ferrules. The dimensions are (27.9 x 22.2 x 17.6) mm (width x height x depth). Depending on the conductor type, this PCB terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 2.5 mm². 

# Tin is used for coating the contact surfaces. This PCB terminal block is operated with a push-button. THT is used to solder the PCB terminal block. Insert the con­ ductor into the board at an angle of 45°.. Page 1/6 Version 29.04.2026 Continued on next page
