Delivering exactly what you want when you want it!

McCaltek/Sicaltek Group was established in 1974. We have focused our total energy into the Research & Development and the manufacturing of  both standard and military custom computer, telecommunications and wire harness assemblies with copper or fiber optics connectivity.  We have a vast inventory of standard telecommunication, networking, industrial and computing cables and assemblies.


We produce our own products in our facilities both here in the US and overseas. We have facilities under 100% direct ownership in Taipei and Taiwan. All of our products are ISO 9001 certified.


"In Constant Pursuit of Excellence in Innovation, Service and Quality"  is the corporate philosophy of McCaltek/Sicatek Group. We insist on hard work and step-by-step progress rather than speculation and short-cuts. Our QA Department utilizes a triple testing program during production; Hi-Pot Testing, Pull Testing, as well as Temperature & Humidity Testing.  We are proud of our successful standing as an OEM supplier.


We will continue to seize upon market trends to supply our customers with fast and reliable service and top of the line products.
