Because the needs of our customers are ever evolving, we're continually developing new products that leverage emerging technology and the growing Industrial Internet of Things (IIoT).

The Sealevel Facility
Located in the upstate of South Carolina, our modern, 52,000-square foot facility sits on a 17-acre site. To protect electronic components during assembly and test, we've installed over 20,000 square feet of ESD tiling.

Our Quality Commitment
We are committed to the design and manufacturing of reliable, quality communications products and dedicated to providing 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 Automate 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 tables.

Putting the I/O in IIoT
Sealevel's SeaConnect family of IIoT products is one of our most popular and fastest growing lines. Currently, we are working with over 40 accounts to implement cellular-connected applications in a variety of vertical markets.
