PCB terminal block, 253 Series, operating tool Our PCB terminal block (item number 253-104) is the perfect way to connect conductors quickly and securely. It is ideal for custom installations with different mounting types. Ensure that the strip lengths are between 8.5 and 9.5 mm when connecting conductors to this PCB terminal block. Featuring two conductor terminals along with PUSH WIRE® as well as PUSH WIRE®, this product is highly versatile. Our trusted PUSH WIRE® connection offers the fastest method for clamping conductors. It utilizes the conductor's stiffness to overcome the clamping spring's contact force. The dimensions are (22 x 16.6 x 12.8) mm (width x height x depth). Depending on the type of conductor, this PCB terminal block is ideal for conductor cross sections ranging from 0.5 mm² to 1.5 mm² on one side and for conductor cross sections from 0.5 mm² to 1.5 mm² on the other side. The contact surface is coated with tin. An operating tool is used to operate this PCB terminal block. THT is used to assemble the PCB terminal block. The conductor is designed to be inserted into the board at a 0° angle..
