Explore performance details, construction highlights, applications, and technical information in one clear overview.
The MN203S is a magnetically coded sensor designed to detect a defined coded target. Its contactless operating principle allows position monitoring without mechanical contact between the sensor and actuator. This supports reduced wear and reliable operation during repeated machine cycles. The rectangular housing provides a compact installation format. It is suitable for industrial machine monitoring applications.
The sensor provides two normally open potential-free outputs for suitable control applications. These outputs can be used to monitor the defined actuator position. The potential-free switching arrangement provides flexibility when integrating the sensor into control circuits. The sensor is designed for dependable switching performance. Correct system-level wiring should follow the applicable machine safety design.
The MN203S provides IP67 and IP69K protection when the cable arrangement is suitably protected. Its industrial construction supports demanding machine environments. The operating temperature range extends from -25 to 80 °C under specified conditions. Shock and vibration resistance support use on industrial machinery. This makes it suitable for applications exposed to mechanical movement and environmental stress.
The sensor can be used for monitoring guarded machine positions and coded actuator states. It is suitable for industrial equipment requiring reliable non-contact position information. The 0.1 m cable configuration supports compact machine wiring. Its defined actuator concept helps provide controlled detection. The MN203S is suitable for machine automation and safety-related monitoring where the complete system is appropriately designed.
