Jumper Wires, Pre-Crimped Leads

Jumper Wires, Pre-Crimped Leads are a general term for a type of pre-crimped jumper products in electronic components, which are mainly used to quickly build circuit connections or realize signal transmission between modules. With its plug-and-play characteristics, this type of product significantly shortens the deployment cycle of electronic systems and is an indispensable basic component in laboratory development and industrial equipment.

1. What are Jumper Wires and Pre-Crimped Leads?

It is composed of multiple strands of copper core wires, and the two ends are pre-crimped with terminals of different specifications (such as male, female, rectangular connectors, etc.), without the need for users to solder by themselves.

 

It provides standardized combinations of multiple colors, lengths (such as 2 inches, 6 inches, and 12 inches), and termination forms (M-F, F-F, M-M).

 

2. Where are Jumper Wires and Pre-Crimped Leads Used?

Rapid Prototyping Design: With the crimp connector housing, it can be flexibly assembled into a customized harness, which is suitable for temporary connection of modules such as development boards and sensors.

Industrial Automation: As a rectangular cable assembly, it is used for the stable connection of high-density ports in control cabinets and PLC equipment.

‌Equipment Maintenance‌: Simplify the repair and upgrade process of electronic equipment by replacing damaged cables or expanding interfaces‌.

 

3. What are the ‌Technical Parameters of Jumper Wires and Pre-Crimped Leads?‌

‌Electrical Performance‌: Common voltage rating is 100V, and the current carrying range covers 700mA to higher specifications‌.

‌Cable Specifications‌: The wire diameter is mainly 24 AWG, and some models support 20 AWG or thinner 28 AWG for higher current‌.

‌Durability‌: Industrial-grade insulation materials are used to adapt to wide-temperature environments and frequent plug-in and unplug scenarios‌.

 

4. How to Choose Jumper Wires and Pre-Crimped Leads?‌

‌Mainstream Brands‌: Including Pololu, Molex, JST, etc., providing product lines with different packaging forms and certification standards (such as RoHS).

‌Selection Points‌: Pay attention to the connector type (such as rectangular, D-Sub), pin number matching, cable length, and termination direction (straight-through or bifurcated)‌.
