RSF Elektronik

What RSF Elektronik does

RSF Elektronik Ges.m.b.H. is an Austrian precision-measurement manufacturer, headquartered in Tarsdorf and operating as a wholly-owned subsidiary of HEIDENHAIN since at least 2023. The company designs and produces high-precision linear encoders (exposed series MC 15, MS 14, MS 15, MS 25, MS 45 and sealed series MSA 7xx, MSA 8xx, MSA 170, MSA 373/374/375), modular angle encoders (absolute MCR/MCS 15/16 and incremental MSR 15/45, MSS 15 series), and precision linear and circular graduations manufactured using thin-layer technology on glass or carrier substrates. Its core technical differentiator is contact-free single-field scanning, enabling measurement resolutions from the micrometre to the nanometre range, with accuracy grades of ±5 µm/m. Products serve industrial automation, CNC machine tools, robotics (including cobots with collision monitoring), and — newly certified — maritime and hazardous (ATEX) environments.

The company operates exclusively B2B, selling engineered encoder subsystems to OEMs and system integrators on quote-based, multi-year contracts, with no public consumer pricing. Distribution is executed almost entirely through HEIDENHAIN's global subsidiary network (France, UK, Netherlands, USA, South Korea, Switzerland, Italy, Japan, Singapore, Sweden, Belgium, China, Taiwan) plus regional distributors (Turkey, Israel, Spain, Portugal, Finland), giving RSF reach into 25+ countries without bearing stand-alone channel costs. Manufacturing is split between Tarsdorf (encoders and graduations) and a wholly-owned cable-systems subsidiary in Střítež (Czech Republic). The company holds EN ISO 9001, EN ISO 14001, ATEX (TÜV-A 24ATEX3003Q), DNV maritime, IEC 61010-1, UL/CSA 61010-1, and EcoVadis certifications, and runs apprenticeship pipelines in electrical design, production electronics, mechanical manufacturing, and technical drawing to sustain its technical workforce. Management consists of two Managing Directors, Ulrich Reisecker and Christian Ried.
