PCB terminal block, 257 Series, solder pin dimensions 0.7 x 0.7 mm Our PCB terminal block (item number 257-554) simplifies electrical installations. You can rely on tried and tested safety with these PCB terminal blocks, perfect for a host of applications when designing your devices. 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 reliable 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 (32.9 x 24.2 x 14.2) mm (width x height x depth). 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 push-button (angled). THT is used to solder the PCB terminal block. The conductor is designed to be inserted into the board at a 0° angle..
