PCB terminal block, 257 Series, with 5 mm pin spacing Our PCB terminal block (item number 257-486) ensures effortless electrical installations. You can count on tried and tested safety with these PCB terminal blocks, perfect for a wide variety of applications when designing your devices. Strip lengths must be between 5 and 6 mm when connecting conductors to this PCB terminal block. This product features one conductor terminal and utilizes CAGE CLAMP®. Our highly-rated and maintenance-free CAGE CLAMP® connection makes it easy to connect all types of conductors without having to prepare the conductor. For example, you don't need to crimp ferrules. Dimensions: (182.9 x 24.2 x 14.2) mm (width x height x depth). Depending on the conductor type, 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. This PCB terminal block is operated with push-button (angled). THT is used to assemble the PCB terminal block. The conductor is designed to be inserted into the board at a 0° angle..
