ERNI Electronics (Thailand) Co. Ltd.

About us

In January 2013 the cable manufacturer Abotron became a member of the ERNI Group. This facilitates synergies between connector and cable manufacturing. Thailand based production was renamed ERNI Electronics Thailand Co. Ltd. and extends ERNI's network of manufacturing facilities for cable assemblies. Capabilities are designed for small and medium lot sizes for both cable harnesses and full product assemblies.

Our factory in Lamphun is fast becoming ERNI Group's second hub for connector manufacturing in addition to our factory in Adelberg, Germany. Production of several product lines has been transferred to Lamphun to benefit from low costs and exemplary quality facilities. As a result, production lines for new connectors are set up from launch in Lamphun to enhance our range of products.

We look forward to expanding our customer base as well as continuously improving our worldwide services to meet and exceed customer expectations. With almost 30 years of experience we provide excellent contract manufacturing and the complete outsourcing of projects ranging from simple consumer devices to complex and challenging high end subassemblies for various industries.
