How do I order a product or repair online?
First, find your product in the webshop. On the product page, you can add the product or repair to your shopping cart. Then proceed to checkout. 
Why should I choose JC-Electronics?
You can rely on a stock of 300,000 pieces of industrial electronics from leading top-quality brands, both new and refurbished. Therefore, you can also find drives, PLCs, HMIs, and industrial PCs that are no longer produced with us. You always get a 2-year warranty. Additionally, refurbished products are circular, helping you reduce your ecological footprint.  Good to know: New products and tested refurbished products ordered before 16:00 CET are shipped the same day.
Why can I trust refurbished electronics from JC-Electronics?
All products are thoroughly cleaned, defects are repaired, and weak elements are proactively replaced. If they pass the endurance test, the products can be sold. You can recognize them by the JCertified warranty seal. The entire process has received the RecQ quality mark from DEKRA and the ISO14001:2015 certificate
How much warranty do I get on a product?
You always get a 2-year warranty on products, both refurbished and new. This is twice as much as the standard factory warranty from many manufacturers.
Are all products available from stock immediately?

Why should I buy refurbished electronics?
