What ERNI Electronics does

ERNI Electronics, legally ERNI Group AG, is a German designer and manufacturer of electronic connectors founded in 1947 and headquartered in Adelberg. The company builds a specialized portfolio of board-to-board, wire-to-board, and power connectors organized around proprietary product families including MicroStac, MicroCon, MicroSpeed, SMC, MicroBridge, MiniBridge, MaxiBridge, PowerElements, and Power Taps. Differentiated engineering choices include fine-pitch grids down to 0.8mm, transmission rates up to 25 Gbit/s with EMC optimization, and current handling up to 360A, addressing space-constrained and high-reliability applications.

ERNI's stated end markets are factory automation, automotive, medical technology, industrial machinery, industrial railway, and building automation, with factory automation and automotive flagged as primary segments. The company generates revenue through hardware sales of connector products; pricing is not publicly disclosed and customers are directed to TE Connectivity for quotations. Since its acquisition by TE Connectivity (NYSE:TEL), ERNI has been repositioned as a retained sub-brand within TE's industrial connector portfolio, with all go-to-market activity executed through TE's global direct sales organization, authorized distributors, and corporate e-commerce channels.

ERNI employs 101–250 people, operates as a private subsidiary, and no longer reports standalone financials. Customer support, sample ordering, and technical documentation are delivered through TE Connectivity's web platform and account management infrastructure.
