Always in step with developments: To capture the data accurately, you need devices which the complete range of detecting devices you can rely on. Our comprehensive range of SIRIUS Whatever information you need and no matter how you want detecting devices is just what you need for nearly any to get it, our portfolio offers the right solution. From standard field-level application. Our mechanical high-precision sen- position switches in a plastic or metal enclosure for any con- sors dependably detect any motion sequence, convert the ceivable standard or safety-related application, to position event into electrical signals and transmit the data to your switches with short-stroke contact block for high-precision dis- control systems, so that you can immediately shut down connect, and position switches with separate actuator or with your machines and systems if a fault occurs. Reliably and solenoid interlocking, e.g. for the secure interlocking of with everything under control. protective doors. We also offer a complete range of non-contact sensors to help you monitor the entire process in any application. Our portfo- lio includes optical sensors such as light curtains and laser scanners as well as our dependable family of proximity switches. Whether you use the switches for standard functions or in safety circuits, no unexpected movement escapes our detect- ing devices no matter how harsh the conditions are. Positive- opening IEC 60947-5-1 compliant contacts are suitable for use as mechanical position switches in applications up to EN 954-1 Category 4. 2 Introduction
