<h2>PCB terminal block, 744 Series, operating tool</h2><br/><br/>This PCB terminal block (item number 744-304) is designed for easy and secure connections. You can count on proven safety with these PCB terminal blocks, perfect for a wide range of applications when designing your devices. Conductors can only be connected to this PCB terminal block if their strip length is between 8 and 9 mm . Featuring one conductor terminal along with PUSH WIRE®, this product is highly versatile. Our reliable PUSH WIRE® connection offers the fastest method for clamping conductors. It utilizes the conductor's stiffness to overcome the clamping spring's contact force. Dimensions: (14.9 x 10.1 x 12.5) mm (width x height x depth). Depending on the conductor type, this PCB terminal block is ideal for conductor cross sections ranging from 0.5 mm² to 1.5 mm².<br/><br/><h3></h3><br/><br/>Tin is used for coating the contact surfaces. An operating tool is used to operate this PCB terminal block. THT is used to assemble the PCB terminal block. Insert the conductor into the board at an angle of 0°..<br/>
