Swelex

What Swelex does

Swelex AB is a Swedish technical distributor of electronic components and engineered connectivity solutions, headquartered in Farsta, Stockholm, with a warehouse and cable-assembly production facility in Gävle. The company distributes 12 core product categories spanning connectors, cabling and connectivity, EMC/RFI/EMI shielding, sensors and measurement, thermal management, RF and microwave components, visual indication and lighting, cooling fans and airflow, electronic enclosures, power supplies and relays, safety products, and system solutions / contract manufacturing. It serves 8 vertical markets including industrial automation (primary), aerospace / space / defence, MedTech, IT and telecom, transport and railway, security, energy, and HVAC, with named partnerships to Tier-1 component manufacturers such as Hirose, Smiths Interconnect, Omnetics, ept GmbH, Delta Electronics, TE Connectivity, and Eaton, plus Nordic distribution rights for AC Tasarım and Heatit Controls.

The business operates on a quote-based distribution model with two pricing tiers — standard products (2-7 working day quote delivery) and customized assemblies (10-14 working day quote delivery) — and combines a field sales force covering Sweden and the wider Nordic region with an inside sales team, technical sales representatives, and application engineers. Revenue is generated through one-time product sales augmented by professional services for customer-specific cable assemblies, EMC gaskets, and system integration work. Distribution is supplemented by direct go-to-market activities including trade show participation (Electronics Fair, Evertiq Expo, Elmässan, Data Centre Expo), on-site customer mini-fairs, a proprietary 'Tech Talk' content platform, and an EMC educational publication.

Swelex AB was formed in December 2023 by unifying Stig Wahlström Elektronik AB (founded 1951), SATCO Komponent AB, and Jolex AB under a single brand, and in 2026 it absorbed Stig Wahlström Automatik AB to add cable-assembly and soldering production capacity. The company is a wholly-owned subsidiary of the Swedish technology trading group Addtech Nordic AB. Certifications include ISO 9001 and ISO 14001 (Intertek, 2024), with EN 9100 and EN 9120 in progress for aerospace and defence distribution, and the company received an EcoVadis Silver Medal for sustainability in May 2025.
