CONNECTRONICS, INC. provides quality network cables, custom-designed cable assemblies, fiber optic and wire harness assemblies without the long lead-times normally associated with build to order products. Since 1978, our strict quality control practices insure your cables will arrive as expected each and every time. All cable assemblies are fully tested and comply with all applicable standards. We are ISO 9001-2008 Certified and have staff members certified to instruct and inspect in accordance with IPC/WHMA-A-620. Our employees are well motivated and receive continuous training. They take pride in their work and are anxious to go the extra mile to earn your trust.

Custom Assembly

We can produce virtually any connectorized cable assembly from your drawings or pinout specifications. Complete customization is available including special labeling.

Wire Harness

Used in medical, aerospace, power control, telecommunications and a host of other applications. We are currently building complex harness assemblies for flight simulators, medical equipment and communication distribution systems.


Soldering is as much an art as it is a skill. Few cable manufacturers have the expertise to offer this service. At Connectronics, our experienced solder technicians have undergone IPC/WHMA-A-620 training and are certified by our in-house instructors to both solder and inspect. They are good at what they do and are eager to tackle your solder job no matter how complex or tedious.


Connectronics offers both CAT5e and CAT6 patch cables in various lengths and colors. All cables are fully certified to exceed TIA/EIA standards. Certification documentation is included with each cable.

Every assembly is tested at least TWICE!

During our manufacturing process, each assembly is thorougly tested during various stages of assembly. When completed, a final series of tests and inspections are performed which include electrical parameters, cosmetic features, correct labeling, etc. This extensive testing insures that you get exactly what you ordered with the quality you expect.

Connectronics, Inc. is ISO 9001-2008 Certified.
