PCB terminal block, 2621 Series, with 3.5 mm pin spacing Our PCB terminal block (item number 2621-3106) simplifies electrical installations. It offers the flexibility needed for different mounting types. Conductors should only be connected to this PCB terminal block if their strip length is between 8 and 9 mm . This product features one conductor terminal and utilizes Push-in CAGE CLAMP®. Push-in CAGE CLAMP® technology provides a universal connection solution for any type of conductor. It allows both solid and fine-stranded conductors with ferrules to be inserted directly into the clamping point without the need for tools. The dimensions are (22.5 x 18.1 x 13.5) mm (width x height x depth). Depending on the type of conductor, this PCB terminal block is suitable for conductor cross sections ranging from 0.14 mm² to 1.5 mm². Tin is used for coating the contact surfaces. An operating tool is used to operate this PCB terminal block. The PCB terminal block is designed for THT soldering. Insert the conductor into the board at a 90° angle..
