PCB terminal block, 237 Series, operating tool Our PCB terminal block (item number 237-136) is the perfect way to connect conductors quickly and securely. It is a universal connector that can be used practically anywhere, e.g., as a pluggable PCB connector, panel feedthrough header, connector for rail-mount terminal blocks, or a floating connector for different mounting methods. Conductors can only be connected to this PCB terminal block if their strip length is between 5 and 7 mm . This product features one conductor terminal and utilizes a screw connection. Products with screw-clamp connections are easy to reuse on-site, you can replace wires and devices using standard hand tools. This PCB terminal block is suitable for conductor cross sections ranging from 0.5 mm² to 2.5 mm². 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. Insert the conductor into the board at a 0° angle..
