What HEJM does

HEJM Automatisierungstechnik GmbH is a privately held German industrial-electronics specialist headquartered in Radolfzell that develops software and hardware for positioning systems and manufactures flexible industrial electronics. The company serves machine manufacturers and industrial automation companies through a portfolio organized into four families: controllers (Steuerungen), axis modules (Achsmodule), displays (Anzeigen), and customized solutions (Kundenspezifische Lösungen). Core technology rests on a modular hardware and software building block system that supports both standardized catalog products and bespoke designs delivered from a single Radolfzell site covering development through production.

The controller line spans the Linux-based TEPC industrial PC and a series of positioning controllers (PS312, PS4x1, PS7x1, PS7x2, PS511, PS811, PS821) with varying axis counts, display types and I/O. Axis modules include the DR300 series and SAM131/161/241 servo modules for brushed and brushless DC motors, complemented by MC231, MC3x1 and MC531 displays for measurement and dosing. The customized solutions family covers the LBX Industry 4.0 gateway (ARM Cortex-A53, integrated web server, digital/analog I/O), LS200 magnetic measuring system, RGB Control Board, CC261 current monitor, and VCM100 voltage/current measuring device—together enabling retrofit, preventive maintenance and machine-to-IT data transfer use cases.

HEJM operates a direct sales model with phone, email and web contact channels, and a bilingual German/English website indicating some international intent, although the named served geography is DACH. Revenue is generated through hardware sales of controllers, axis modules and displays and through professional services for custom electronics development, including software customization for small-series applications. The company is led by two managing directors—Jürgen Mandlmaier and Daniel Fürst—with no disclosed external investors, funding rounds, subsidiaries, partnerships, or M&A activity.
