PCB terminal block, 237 Series, with 10 mm pin spacing Our PCB terminal block (item number 237-113) simplifies electrical installations. It is ideal for custom installations with different mounting types. Ensure that the strip lengths are between 5 and 7 mm when connecting conductors to this PCB terminal block. Featuring one conductor terminal along with a screw connection, this product is highly versatile. Screw-clamp connections can handle currents from a fraction of an ampere all the way up to several hundred amperes at low to moderate frequencies. Depending on the type of conductor, this PCB terminal block is ideal for conductor cross sections ranging from 0.5 mm² to 2.5 mm². Tin is used for coating the contact surfaces. This PCB terminal block is operated with an operating tool. The PCB terminal block is designed for THT soldering. The conductor is designed to be inserted at a 0° angle..
