PCB Screw Terminal Connector Kit, 5mm Pitch

A 5mm pin pitch gives this screw-terminal connector kit a defined spacing for PCB wiring, while the screw-clamp format is intended to hold compatible wires in place. It includes 2-pin, 3-pin, and 4-pin connectors, so you can choose a block length that suits a particular connection rather than relying on one fixed layout. For a small electronics project, that can mean fitting the connector to the board and landing the wire with a screwdriver instead of making a permanent soldered connection. The kit is listed as 111 pieces, though the quantities given for each pin count add up to 110.

Getting the most from it

Use the pin count that matches the connections you need, and check the board layout before choosing a block: the stated spacing is 5mm (0.2 inch). The terminals are specified for 26–14 AWG wire, with a rated voltage of 300V and rated current of 10A. Those ratings are useful selection points, not a substitute for checking the requirements of the full circuit and installation.

The blocks can be spliced together, which offers some flexibility when a project needs a different run of positions. For example, while assembling an electronic module, you could use a shorter block for a couple of signal wires and a longer one where several connections sit together. The product description identifies applications including electronic modules, automatic controls, calculators, household appliances, and industrial equipment. It does not give dimensions beyond the pin spacing, so space-constrained layouts may need closer attention.

Why it’s worth it

The practical draw is having several common connector sizes in one kit, rather than buying a single pin count that may not suit every board. That makes it more adaptable for bench projects involving different PCB connections. If you prioritize a basic, modular way to terminate compatible wires, this format may be useful, if you prefer a soldered, fixed connection, a screw terminal is a different approach and may not be what you want. Worth considering if your board layout uses the stated pitch and your wire falls within the listed gauge range.

Key features

• 2-pin, 3-pin, and 4-pin PCB terminal blocks, listed as 60, 40, and 10 pieces respectively.
• 5mm (0.2 inch) pin spacing, blocks can be spliced together.
• Rated for 300V and 10A, and specified for 26–14 AWG wires.
• Green connectors, the product name also mentions a screwdriver, but the description does not clearly confirm its inclusion.

One detail worth noting before ordering: the stated counts total 110 connectors, not the 111 pieces in the kit name. The description also gives a temperature range of -40 to 105 without specifying its unit, so it is not possible to interpret that range confidently. It says the product is for industrial purposes, not medical use. It may not suit you if you need a confirmed piece-by-piece count, a clearly specified temperature range, or documentation for a particular installation. Without having tried it, those gaps are the main reasons to verify the listing details against your project needs.

Is it worth it?

This kit makes the most sense when you need several PCB terminal-block sizes, use 5mm spacing, and can work within the stated wire and electrical ratings. Its mix of pin counts is more flexible than choosing one connector size for every job, but the unclear total count and unspecified temperature unit reduce certainty. Buy it for straightforward, compatible electronics or control-board wiring, choose another connector approach if your design calls for soldered joints or if exact kit contents and fully specified operating conditions are essential.
