Feedthrough terminal block, 741 Series, solder pin dimensions 0.7 x 0.7 mm Our feedthrough terminal block (item number 741-508) simplifies electrical installations. Ensure that the strip lengths are between 5 and 6 mm when connecting conductors to feedthrough terminal block. This product incorporates one conductor terminal and utilizes CAGE CLAMP®. 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. Dimensions: (76.5 x 22.5 x 12.8) mm (width x height x depth). Depending on the type of conductor, feedthrough 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. The feedthrough terminal block is designed for THT soldering.
