    Because we take safety to the next level

    The intelligent deTec safety light curtains are ideal for the protection of hazardous areas, entrances, and hazardous points. Modern technologies such as NFC and IO-Link with their diverse functionality increase the level of automation and thereby productivity. The result: Simple on-site diagnostics, fast commissioning, and comprehensive data for automating downstream processes. Furthermore, the flexible connection concept in combination with the uniform housing design ensures low cabling, installation and configuration costs. The required functions are activated without software via the matching system plug. Thanks to different enclosure ratings as well as variants for explosion-hazardous areas, deTec also provides solutions for applications in harsh environments.

    The deTec unites safety and automation in one sensor

    In addition to a high level of safety, intelligent safety sensors also offer a wide range of automation options. The deTec4 product variant not only protects people, but also provides valuable data for downstream process steps via IO-Link. This means you don’t need as many sensors. The sensor also makes a valuable contribution to the mobile maintenance of your machines or plants.
    Versatile automation options Use extensive process data for downstream automation processes, e.g. for height measurements.
    More efficient cause analysis Comprehensive service data allows you to perform predictive maintenance, e.g. when sensors start to get dirty, and for quick and easy cause analysis.

    Increase the level of automation and process transparency of your machines and plants

    From a single mold and always flexible

    The deTec safety light curtain is ready for use in no time at all. Thanks to the uniform housing and mounting concept as well as standard cables, the device is always equally easy to implement in the machine design.
    Flexible connection design Thanks to its high modularity, the deTec allows for functions to be activated quickly and easily by means of the appropriate system plug for each application, and completely without software.
    Uniform housing and mounting concept deTec and brackets are tailored to one another and flexible to use. Housing profile, end caps, and brackets are all from a single source and offer a secure hold as well as many alignment possibilities.

    Benefit from minimal cabling, installation and configuration work

    Safety light curtains for the strict requirements of your industry

    Depending on the area of application, the topic of safety encompasses other aspects: in food production and processing, hygiene standards must also be taken into account. In explosion-hazardous areas, it is a matter of compliance with explosion protection standards. In the machine tool industry, the resistance of the safety light curtain to the chemicals in coolants, lubricants and cleaners often plays a decisive role. When protecting machines and systems, there are also high requirements for shock and vibration resistance and thus sensor availability.
    High hygiene standards With its easy-to-clean housing made of food-safe plastic and stainless steel, the deTec IP69K is ideal for protecting washdown zones.
    Explosive areas Different Ex zones can be protected by different deTec variants.
    Resistant to chemicals The deTec HG variants with a front screen made of chemically-hardened float glass is especially resistant to coolants and lubricants.
