PCB terminal block, 257 Series, gray Easily, quickly and safely connect conductors with this PCB terminal block (item number 257-552). It is a universal connector that can be used practically 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 can 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 is highly versatile. Our highly-rated 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 (17.9 x 24.2 x 14.2) mm (width x height x depth). Depending on the type of conductor, this PCB terminal block is ideal 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 at an angle of 0°..
