PCB terminal block, 237 Series, 0 °conductor entry to board Connect conductors quickly and safely with this PCB terminal block (item number 237-103). It offers the flexibility needed for different mounting types. Ensure that the strip lengths are between 5 and 7 mm when connecting conductors to this PCB terminal block. Featuring one conductor terminal along with a screw connection, this connector outperforms the competition. When properly tightened, screw-clamp connections ensure that wires are connected securely—both physically and electrically—as they contact a large section of wire. 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. An operating tool is used to operate this PCB terminal block. THT is used to solder the PCB terminal block. Insert the conductor into the board at a 0° angle..
