PCB terminal block, 257 Series, with 5 mm pin spacing Our PCB terminal block (item number 257-847) makes connecting wires quick and easy. You can count on tried and tested safety with these PCB terminal blocks, perfect for a host of applications when designing your devices. Ensure that the strip lengths are between 5 and 6 mm when connecting conductors to this PCB terminal block. This product incorporates one conductor terminal and utilizes CAGE CLAMP®. Our CAGE CLAMP® connection offers a safe 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 (7.8 x 24.2 x 14.2) mm (width x height x depth). Depending on the type of conductor, this PCB terminal block is designed for conductor cross sections ranging from 0.08 mm² to 2.5 mm². Tin is used for coating the contact surfaces. Push-button (angled) is used to operate this PCB terminal block. THT is used to solder the PCB terminal block. Insert the conductor at a 0° angle..
