LEMO connector

What LEMO connector does

LEMO is a privately held Swiss manufacturer of high-performance push-pull circular connectors and cable assemblies, founded in 1946 in Ecublens VD, Switzerland. The company designs and produces modular and custom interconnect solutions for demanding environments, with product lines spanning ORIGINALS, REDEL, OPTIMA, SUPREME, and SPECIALTIES, alongside technical cables and cable assemblies manufactured by its wholly-owned subsidiary Northwire, Inc. (acquired 2014). Its underlying technology centers on a proprietary push-pull locking mechanism, hermetic and high-voltage variants, signal-integrity-optimized mixed configurations, and specialized capabilities including fibre optic, RF, and high-flex-life retractile cable coiling. Approximately 90% of production is vertically integrated and based in Switzerland, with employees operating in more than 20 countries.

LEMO's business model is built on quote-based hardware sales of connectors and cables supplemented by professional services including cable assembly, customized interconnect design, and end-to-end signal integrity engineering. The company distributes exclusively through its own global subsidiaries and authorized dealers, with a self-serve Product Finder tool for quote and sample requests, and runs an enterprise field-sales motion across nine vertical segments: medical (primary), security and defence, test and measurement, semiconductor, energy and industrial, audio video, motorsport, transportation/aerospace/UAV, and specialities. All production sites are ISO 9001 certified at minimum, with Northwire additionally certified to ISO 13485 (medical), AS9100 (aerospace/defense), and ISO 17025.

The customer base spans medical device OEMs, defense and aerospace primes, semiconductor equipment manufacturers, and industrial automation customers, with no named logo-level customer disclosures. Pricing is not publicly disclosed and is set per quote for both catalogue COTS items and custom configurations. Leadership is headed by CEO and President Alexandre Pesci; Northwire CEO Katina Kravik and LEMO Benelux MD Niels Zonnenveld round out the operating team alongside General Counsel Marcel Kochan and Head of Field Application Engineering Serge Buechli. Recent strategic activity centers on five new product launches across 2024-2025 (REDEL SP IP68, REDEL P Series, OPTIMA D Series, M Series Single Pair Ethernet, and a multi-coax solution) and continued use of the European Distribution Center in the Netherlands for European market coverage.
