Our Brands
We provide reliable, innovative, and smarter automation products tailored to each customer's specific needs and requirements under the Comark and Nematron brand names.
In June 2014, Nematron Corporation was acquired by Comark. This strategic acquisition strengthened Comark’s position in the industrial automation market with both an established product line and distribution channels.  Nematron’s highly engineered products are primarily focused on the severe and hazardous industrial automation markets and carry a number of 3rd party approvals required to participate in this space.   Nematron’s operations have been fully integrated into Comark’s Milford, MA headquarters.
Going forward, Comark will retain Nematron as our brand primarily targeted at severe and hazardous industrial automation applications.
In December 2014, Total Control Solutions (TCS) was acquired by Comark.  This strategic acquisition bolstered Comark’s capabilities to custom design industrial computers to meet the specific needs of OEM’s in the industrial automation market. TCS’s operations have been fully integrated into Comark’s Milford, MA headquarters.
Going forward TCS will be rebranded with the Comark brand, while retaining all of the former capabilities TCS offered.
In July 2017, Data Ltd. Inc. (DLI) was acquired by Comark. The combination of Comark and DLI brings the consolidated customer base an industry-leading choice of industrial computing solutions. DLI’s mobile computing technology is a perfect complement to Comark’s high-value, rugged and reliable industrial computing solutions. The expanded product line will benefit Comark and DLI customers who are looking for compact, innovative and ruggedized solutions.
