Nominal voltage and current (make sure that the terminal blocks meet the voltage and current that will flow throughout your PCB)Īmong the most popular terminal blocks with hardware designers, you will find a TE Connectivity terminal block with a nominal current of 13.5 A, 300 V, 5.08 mm pitch.Type of connection (normally you will have either a screw-in or plug-in connection).Mounting type (DIN rail versus mounted on a PCB).Terminal blocks serve as an effective method of connecting wires, whether it’s to ground them, secure multiple wires together, or provide communication between a device and a controller.Īlthough terminal blocks can be classified according to their device type and structure, there are some extra considerations that should be taken into account when selecting a terminal block for your design.

They’re built from an insulating frame and a clamping component. T erminal blocks offer designers an easy and secure way to transmit data, signals, and power to your printed circuit board designs.
