Sealevel Releases Locking USB 3.0 Cables to Meet Increasing Industrial & Rugged Demands

November 17, 2022

Sealevel Systems announces the release of three new high-retention, SeaLATCH® locking USB 3.0 cables. Designed for shock and vibration tolerance, and to support an increasing number of USB 3.0 devices, the locking connectors ensure reliable, consistent performance in any application or environment. 

Increasing Need for Locking, High-Retention USB Solutions

In recent years, RS-232 ports have largely been displaced from computers as USB ports emerge as the preferred serial interface for industrial environments. Data rate speed and durability are the twoprimary factors influencing this migration. With the introduction of USB 3.2 in 2017, data rates that are up to 100,000 faster than RS-232 have been achieved. Additionally, the small pins on traditional serial ports can be easily bent, minimizing their reliable operation in extreme environments where shock, vibration, and other physical disturbances are present. However, one of the primary features of USB can also be its downfall:  the USB mechanical connector was intentionally designed to be quickly connected and disconnected. As a result, accidental cable disconnection is a common failure for industrial USB devices. 

About SeaLATCH Locking USB Connectors

Sealevel’s patent-pending SeaLATCH® locking USB connectors feature a thumbscrew that provides a secure, metal-to-metal connection to avoid interrupted operations for critical communications. SeaLATCH locking USB ports are integrated into Sealevel: 

“We’re excited about the increasing applications that benefit from locking connectors. Originally, this was a driver primarily for our military and aerospace customers but now we are seeing drone and UAV use increase across industries – and the inherent vibration makes a solution like SeaLATCH highly desirable,” aid Earle Foster, Sr VP of Sales for Sealevel.
