Fiessler Electronics

What Fiessler Electronics does

Fiessler Elektronik GmbH & Co. KG is a German family-owned manufacturer of optoelectronic industrial safety equipment, headquartered in Aichwald, Baden-Württemberg, and founded in 1956 by Dipl. Ing. Hugo Wolfgang Fiessler. The company is led today by second-generation managing directors Dr. Ing. Lutz Fiessler and Dipl. Kfm. t.o. Götz Fiessler, with the third generation having joined in 2018. Its technology stack is built around infrared-based optoelectronic sensing and a programmable modular safety controller.

The product portfolio is organized into two lines. The Safety Products line comprises the AKAS family of press brake safety systems (AKAS, AKAS-LC, AKAS-SBH, AKAS-SBM), the FMSC modular and configurable safety controller (supporting EtherCAT and Profinet), a range of Type 4 safety light curtains (ULVT, ULCT, BLVT, BLCT) with response times of 6–25 ms and ranges up to 24 m, safety contact mats (STM), and safety foot switches (FE-FS). The Standard Products line extends the same optical sensing platform into non-safety-rated industrial automation: light curtains, GLSL hole detectors, CCD sag sensors, GR infrared barriers, sentinel traffic lights, coding strips, and standard foot pedals. Supporting tools include SISTEMA safety-evaluation libraries and FMSC Studio configuration software. All safety products meet Type 4 (IEC 61496), SIL 3 (IEC 61508), and PL e (EN ISO 13849); the company is ISO 9001 certified and a long-standing member of national and international standardization committees. Fiessler holds patents across EMC technology, AKAS, FMSC, and safety light curtain designs.

Commercially, Fiessler operates a hardware-led business with attached professional services — risk analysis, application consulting, machine control, safety inspections, modernization, spare parts, EMC service, and SISTEMA support — sold predominantly through direct enterprise field sales. Distribution is handled by over 20 country-specific representatives covering five continents and 27+ countries, supplemented by multilingual websites (German, English, French, Turkish) and category-specific technical sales phone lines. Customers are industrial manufacturers (CNC machining, press brake and folding operations, automated production systems) and metal fabricators requiring certified operator protection. The company is the world market leader in press brake safety systems and a recognized global technology leader in safety light barriers.

Core offering

Fiessler Elektronik manufactures and sells proprietary optoelectronic industrial safety systems for protecting machine operators in manufacturing environments. Its offerings center on the AKAS press brake safety system (world market leader), the FMSC modular safety controller, a Type 4 safety light curtain family (ULVT/ULCT/BLVT/BLCT), STM safety contact mats, and FE-FS safety foot switches, alongside a complementary standard product line of light curtains, hole detectors, sag sensors, infrared barriers, sentinel traffic lights, coding strips, and standard foot pedals. The company also delivers professional services including risk analysis, application consulting, machine control, safety inspections, plant modernization, spare parts supply, EMC service, and SISTEMA software support.

Product overview

Fiessler Elektronik is a technology leader in industrial safety systems, organized around a core modular safety controller (FMSC) and two main product lines: Safety Products and Standard Products. Safety Products include the AKAS® press brake safety system (including AKAS-LC, AKAS-SBH, and AKAS-SBM variants for folding machines), the FMSC modular safety controller as the central programmable platform, and a comprehensive family of Type 4 safety light curtains (ULVT, ULCT, BLVT, BLCT), safety contact mats (STM), and safety foot switches (FE-FS). Standard Products encompass non-safety-rated industrial automation sensors including light curtains, hole detectors (GLSL), sag sensors (CCD), infrared barriers (GR), sentinel traffic lights, coding strips, and standard foot pedals. Fiessler's SISTEMA libraries and FMSC Studio demo software support safety evaluation and controller configuration. The company holds ISO 9001 certification and its products meet Type 4 (IEC 61496), SIL 3 (IEC 61508), and PL e (EN ISO 13849) safety standards. With over 70 years of experience and representatives in more than 20 countries across five continents, Fiessler serves the metalworking, automotive, and general manufacturing industries.
