It is a useful thing on your project. Whether you're just trying to make a few quick connections to test your circuit or having trouble making your multimeter leads stay where you need them, these spring-loaded clips are a workshop must-have.
This 12-inch (30-cm) cable has 26 AWG wires and a 3-pin female JST PH-style connector that works with Sharp analog distance sensors that have mating PH connectors. The other ends of the wires are unterminated; they can be cut to length to match your application. The wire color scheme matches the Sharp distance sensor pinout: red for power, black for ground, and white for signal.
