PCB terminal block, 253 Series, PUSH WIRE® Our PCB terminal block (item number 253-107/000-012) is the perfect way to connect conductors quickly and securely. You can count on tried and tested safety with these PCB terminal blocks, perfect for a wide range of applications when designing your devices. Strip lengths must be 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 delivers reliable performance. Our PUSH WIRE® connection uses the stiffness of the conductor to overcome the clamping spring's contact force, allowing faster and easier conductor clamping. Dimensions: (37 x 16.6 x 12.8) mm (width x height x depth). This PCB terminal block is suitable for conductor cross sections ranging from 0.5 mm² to 1.5 mm² on one side and for conductor cross sections ranging from 0.5 mm² to 1.5 mm² on the other side. The contact surface is coated with tin. This PCB terminal block is operated with an operating tool. THT is used to solder the PCB terminal block. The conductor is designed to be inserted into the board at a 0° angle..
