This Degson 3-pin PCB terminal block gives a board a reliable way to accept external wiring without soldering wires directly onto pads, which matters for connections that might need to be reconnected, serviced or swapped later. It features a screw connector with wire protection, so a wire is physically clamped in place by a tightened screw rather than depending purely on a solder joint that could eventually crack under mechanical stress or vibration.
The pitch, meaning the spacing between each of the three pin positions, is 5.0mm, a widely used standard that matches many existing terminal block families and PCB footprints, making it easy to design around or substitute for other 5mm-pitch blocks if needed.
It carries a rated current of 17.5A and a rated voltage of 250V, giving it enough headroom for a wide range of low-voltage power and even some mains-adjacent control wiring, and it is designed to accommodate wire sizes from 16 to 14AWG, corresponding to roughly 1.5mm² cross-sectional area. Contact surfaces are made from tin, chosen for good electrical conductivity and reasonable resistance to corrosion over the terminal's working life.
The block is classified under overvoltage category III/2, a rating relevant to installations exposed to higher transient voltages, such as fixed building wiring, giving some indication of the safety margin built into its design beyond simple low-voltage hobby use.
PCB designers and anyone building a custom board that needs a secure, serviceable way to bring external power or signal wiring onto the board will find this a standard, dependable connector, particularly where solder-only connections aren't robust enough.
