Redel S.A.

What Redel S.A. does

Redel S.A., operating as LEMO, is a Swiss-headquartered designer and manufacturer of high-reliability push-pull circular connectors and complementary interconnect solutions. Founded in 1946 as a family workshop in Sainte-Croix, Vaud, the company organized its portfolio around five connector sub-brands (ORIGINALS, REDEL, OPTIMA, SUPREME, SPECIALTIES) and a wholly-owned cable subsidiary (Northwire), alongside technical cable products and three service lines: cable assembly, customised interconnect solutions, and end-to-end signal integrity services. The underlying technology centers on the proprietary push-pull locking mechanism that LEMO originated in 1958, extended over decades into IP68 sealing, high-voltage, high-power, fiber optic, RF, and mixed-configuration variants optimised for medical, defense, aerospace, and semiconductor use cases.

The business model is a quote-based, enterprise field sales motion targeting OEMs and system integrators in regulated, mission-critical verticals, supported by a global hybrid distribution network of direct subsidiaries and authorized distributors, with quote and sample request workflows originating from the company website. Revenue is generated primarily through hardware sales of proprietary connectors and cables, supplemented by professional services revenue from cable assembly, customised interconnect solutions, and signal integrity engagements. The company is privately held, with no disclosed external investors, and serves what it describes as "thousands of longstanding satisfied customers" across medical, security and defence, test and measurement, semiconductor, energy and industrial, audio/video, motorsport, and aerospace/UAV end markets.
