Jumper Wires, Pre-Crimped Leads

Jumper wires, also known as pre-crimped leads, are electrical cables that terminate with a single bare wire. The end of the wire is crimped, or soldered, to a pin, typically a metal pin, allowing for easy and secure electrical connections. Jumper wires are used for a variety of applications where a quick, reliable connection is required.

Jumper wires can be used for a multitude of applications, such as connecting two printed circuit boards (PCBs) together, connecting a power supply to an electronic device or connecting signals from a sensor to a microcontroller. Jumper wires can also be used to create customized harnesses in cases where multiple connections have to be made between devices.

Jumper wires come in various sizes, each size having different current and maximum voltage characteristics. Typically, jumper wires are available individually, but in some cases dedicated daisy-chained jumper wires are also available. These daisy-chained jumper wires already have pre-made connections that allow for quick and easy connections. Depending on the application, jumper wires can also be supplied with an optical splice that is commonly used in fiber optic systems.

Jumper wires are used in a wide range of applications, but the most common application is for bridging two PCBs together. To bridge two PCBs, one end of the jumper wire needs to be soldered into a hole in the first PCB, while the other end of the jumper wire needs to be soldered into a hole in the second PCB. This will create a connection between the two PCBs and allow for signals, power, or data to be sent from one PCB to the other.

In some cases jumper wires are also used to connect a power supply to an electronic device, or to connect a sensor to a microcontroller. In these types of applications, one end of the jumper wire typically needs to be soldered into a terminal on the power supply, while the other end needs to be soldered into the terminal on the electronic device or sensor. This will create a connection between the power supply and the electronic device, or between the sensor and the microcontroller, allowing the electronics to power up or receive data from the sensor.

Jumper wires are also commonly used for creating customized harnesses. Customized harnesses are used in cases where multiple connections need to be made between two electrical components in a system. To build a customized harness, several jumper wires need to be soldered into the terminals of one device at one end, while the other end needs to be soldered into the terminals on the other device. This will create a customized connection between the two devices, allowing for the signals, power, or data to be transmitted between the two components.

Jumper wires are used in a wide range of applications and are a reliable way to create customized electrical connections. The ease of use, and their versatility, make them a great choice for quick and easy electrical connections.
