Let's talk about us

Our experience basis on knowledge gained through 15 years in the west and central Europe [Great Britain, Deutschland, Poland, Switzerland]. 4TCAB it’s a small private company whose core value is to provide niche products.

Are we special?

Project Miranda – we were looking for per 2 months one type of Amphenol connector which is no longer in production. We found original parts in Hong Kong – Client trusted us and we trusted the client, we decide to spend a few months to find 20pcs of connectors and build a customized wire harness.

Projects Beta – in does projects we get fakes information. This is not faulted our client! Mostly our clients get wrong data or simply have old technical data. – We open the investigation (is it connector exist, how looks the opposite site, we check the graphics, is it original part, we check revision, analyze datasheet, we check application, terminals and model 3D), then we seek around the world to buy 10pcs FCA assembled from 6 modules. 4TCAB creates schematics and builds a special wire harness for our business partner.
