Sealevel Systems, Inc. reinvented the industrial I/O and computing industry with the first RS-422/485 communication adapter for the IBM PC. Since 1986, Sealevel has continued to redefine design, engineering and manufacturing for industrial computers, Ethernet serial servers, USB serial, PCI Express and PCI bus cards, and IoT hardware and software. Today we offer over 350 core products, available in nearly every configuration imaginable.
Located in the upstate of South Carolina, our modern, 52,000-square foot facility sits on a 17-acres site. To protect electronic components during assembly and test, we’ve installed over 20,000 feet of ESD tiling.
We are committed to the design and manufacturing of quality communications products and dedicated to providing reliable products, exceptional service and on-time delivery. Our commitment is further demonstrated by our ISO 9001:2015 certification and extensive on-site testing capabilities. All board-level assembly and testing take place at Sealevel using our state-of-the-art surface mount manufacturing line. All products are visually screened using Automated Optical Inspection (AOI) and 100% of the functionality is tested before shipment. Other equipment to assist in new product design and testing includes X-ray, vibration table and multiple environmental chambers.
Our in-house Engineering department includes hardware, software, mechanical, layout, compliance and test engineering teams. Our hardware design engineers specialize in complex computing and I/O design, excelling in SWaP optimization and functional density application. We have an extensive library of design work that addresses thermal and other environmental challenges that often impact mission critical communications.
