Out of the shadows, into the light

Fiessler Australia & Sensor Measurement

Sensor Measurement is the official partner and distributor for Fiessler Elektronik across Australia and New Zealand. We bring over 70 years of pioneering German safety engineering directly to local industrial sectors, offering comprehensive sales support, expert application engineering assistance, and reliable local technical guidance.

Advanced Optoelectronic Machine Safety & Worker Protection

When high-speed automation and heavy-duty manufacturing machinery require fail-safe protection for operators, companies globally depend on Fiessler. As a world-class leader in optoelectronic safety technology, Fiessler specializes in engineering highly robust, responsive optical guarding systems designed to prevent workplace injuries while maximizing production uptime and efficiency.

Our premium safety solutions ensure strict compliance and secure operations across major industrial setups, including:

  • Metal Press Brakes: Safeguarding operators during bending processes using advanced, laser-guided finger protection systems that adapt to changing tools.

  • Automated Robotic Cells: Implementing invisible optical perimeters to instantly halt robotic machinery the moment a human enters the zone.

  • Packaging & Palletizing Lines: Deploying safety barriers with smart blanking and muting controls to allow materials to pass through while keeping workers safe.

  • Material Handling & Conveyors: Protecting high-traffic access areas with multi-beam safety light grids built for continuous industrial environments.

Our Comprehensive Fiessler Elektronik Product Range

We supply the full portfolio of high-grade standard products and tailored custom safety solutions directly to Australian industries:

  • Safety Light Curtains & Grids (Type 4 / Category 4 compliant for maximum risk protection)

  • AKAS® Laser Safety Systems (The global industry standard for press brake guarding)

  • Safety Laser Scanners (For flexible, programmable 2D area monitoring)

  • Configurable Safety Controllers & Relays (For managing complex, multi-sensor safety networks)

  • Direction-Sensing Light Barriers & Custom Optical Sensors

Every Fiessler solution we provide is engineered to achieve the highest international safety standards (SIL3, PLe, Category 4), minimizing false trips and offering rugged construction that withstands the demanding conditions of Australian factories.

Always ahead of its time

In 1956, Dipl. Ing. H.W. Fiessler founded the company Fiessler Elektronik, with the aim of manufacturing optoelectronic devices. Customer-specific problem solutions have formed the focus of the company’s business ever since.

Work started on the development and production of safety light barriers over 60 years ago. Since those early days, thousands of Fiessler Elektronik light barriers have been successfully installed and used in industrial applications. Today, Fiessler Elektronik is a world leader in the field of light barrier technology.

The company Fiessler Elektronik is now in its second generation of family management. A highly qualified team of employees and an impressive vertical depth of production form the basis for innovative products in the field of safety engineering and customer-specific optosensor technology. A quality assurance system certified to ISO 9001 guarantees customers a consistently high standard of quality across all Fiessler Elektronik products and services.

In safe hands

Wherever industrial production goes on, wherever people work alongside machines, the safety technology in place must be totally dependable. Because it is working to protect not only employees but employers too, who have a legal as well as a moral obligation to provide a safe working environment in line with valid directives. Which makes the development and production of safety solutions a highly responsible job – one that Fiessler Elektronik has mastered with the utmost reliability. Our quality assurance system is certified to ISO 9001 and guarantees a consistently high standard of quality across all our services and products – which all comply with international safety directives without exception. We are also a long-standing member of national and international standardization committees.


The way we treat the environment is another indicator of our well-developed sense of responsibility: Fiessler invests in new energy sources and covers the majority of its energy requirement using the company’s own photovoltaic system.

Patents and pioneering achievements

Technological progress is moving forward at headlong speed. Machines and plants are undergoing continuous further development – and effective safety technology has to keep pace. Fiessler Elektronik has mastered the art of doing just that. As a modern, innovative company, our headquarters in Aichwald in Southwest Germany operates its own efficient research and development department. Here, we recognize new trends early on, come up with new ideas and new impetus and turn these into marketable safety solutions and bespoke systems for individual customers. This outstanding technical problem-solving expertise has gained us far more than just the Baden-Württemberg Innovation Award: It is what makes Fiessler Elektronik a pioneer. And the holder of countless patents in the field of EMC technology, safety light curtains, ABKAS® press brake safety systems and FPSC safety controllers.

One factor you can depend on

Neither too small nor too large: Fiessler Elektronik has the size it needs to assert itself as a global player, but still retain the flexibility to respond to the individual needs of every customer. A precise risk analysis – either on site or using a machine photo – is usually the starting point. On the basis of our in-depth application advice based on individual customer needs, we go on to design and produce a specifically tailored, technically independent system solution which requires no additional switchgear. Our impressive vertical depth of production and the ideal size of our company mean that we can respond rapidly to customer enquiries.

The comprehensive Fiessler product portfolio also includes high-grade safety components, safety software programmed to fit the bill by our specialists, professional commissioning, safety tests in compliance with all the relevant standards and a 24-hour hotline allowing customers to reach us from around the world.
