Hauber & Graf electronics GmbH Distributor für elektronische Bauelemente

What Hauber & Graf electronics GmbH Distributor für elektronische Bauelemente does

Hauber & Graf Electronics GmbH is a German specialist distributor of power electronics components, headquartered in Steinheim an der Murr and founded in 2003. The company focuses on the railway technology (Bahntechnik) and industrial power electronics sectors, distributing power semiconductors (IGBTs, MOSFETs, GTOs, thyristors, diodes, IGCTs), current and voltage sensors, and ancillary components. As an authorized distributor for major manufacturers including LEM, Hitachi Energy, Starpower, Itelcond, Powersem, Rohm, IXYS, Littelfuse, Electronicon, and MacMic, the company has built a portfolio positioned around the accelerating electrification of rail and e-mobility applications across Germany and Europe.

The company's product portfolio includes three flagship offerings: the TEMA4G energy data acquisition system (combining LEM EM4TII+ energy meters with PEMG2 transmission modules certified for railway applications), the FRS/FL coreless integral current sensors (measuring up to 9000A and 42kA respectively), and the Hitachi Energy RoadPak SiC MOSFET modules (1200V/1150A) for electromobility converters. The company operates a direct sales model combining inside technical sales and field sales representatives, with quote-based pricing and no public price list, supplemented by trade fair presence at PCIM Europe and Power2Drive. A secondary "Sonderposten" channel sells surplus and older-batch components at reduced prices.

Since 2024, Hauber & Graf Electronics has operated as a wholly-owned subsidiary of Solicomp GmbH following a full acquisition finalized at a Munich notary office. The company maintains ISO 9001:2025 certification (re-certified July 2025, valid until June 2028) and serves customers through an 11-person team. Revenue is generated through product distribution with pricing determined by manufacturer relationships, volume, and component complexity. The customer base is primarily enterprise B2B in the railway and industrial OEM segments, with no named end-customer logos publicly disclosed.
