Tech Lowdown

Recently, other companies have begun promoting high retention USB connectors as the best solution for eliminating the most common problem with USB devices used in industrial environments – a disconnected cable. We agree that higher retention USB connectors are an improvement – in fact, we have been using high retention connectors on our USB I/O products since 2006.

However, the best way to completely avoid a disconnected USB cable is to secure the connection with Sealevel’s patent-pending SeaLATCH locking USB connector. Before you select your next USB I/O device, make sure you know the facts:

  • Fact! Any standard USB cable will work in any SeaLATCH
  • Fact! SeaLATCH cables are comparable in price to standard high-
    quality USB cables.
  • Fact! The Sealevel solution combining a high retention connector and SeaLATCH locking USB cables offer the highest security against accidental cable disconnection from any manufacturer, period.

At Sealevel, we don't inflate claims about our products. We don't need to. Our products, our support, and our people have been stating the facts for over 20 years. Learn how to incorporate SeaLATCH locking USB into your industrial applications.
