The SCHURTER MSS-IO is an electronic switch designed with a resistive, wear-free sensing principle. Unlike mechanical or capacitive switches, it detects a change in resistance when actuated, which reduces mechanical wear and increases operational life. The switch is sealed with a closed-surface construction, protecting it against water, dust, and cleaning agents. It requires a light actuation force of approximately 1–3 N and is rated for more than 20 million actuations, making it suitable for environments where frequent use and durability are required.
A key feature of this device is its IO-Link interface, which provides bidirectional digital communication with a host controller over a standard M12 connector. IO-Link operates at COM2 speed (38.4 kBaud) and allows engineers to configure parameters, monitor status, and receive diagnostic information during operation. This makes it possible to adjust the switch’s behavior in real time and supports predictive maintenance strategies, which are increasingly important in automated systems.
The switch offers flexible operating modes, including momentary and latching functions, with configurable output types such as PNP, NPN, push-pull, normally open (NO), or normally closed (NC). It operates from a 24 V DC supply and is designed for a wide temperature range of –40 °C to +85 °C. The front housing meets IP67 and IP69K protection ratings, providing resistance to high-pressure cleaning, and the switch is tested for corrosion resistance in salt spray environments according to IEC 60068-2-11.
These characteristics make the MSS-IO suitable for use in automation systems, robotic interfaces, control panels, and installations in hygienic environments such as food processing or laboratory equipment. The combination of a robust physical design with IO-Link connectivity enables integration into Industry 4.0 environments, where digital communication, remote configuration, and system-level diagnostics are essential.
