The miniature float switches of the MR1N series are designed for demanding industrial applications where high media resistance and reliability are required. The 8 mm switch tube enables precise switching points despite its compact design. With a housing made of stainless steel 1.4571 and a float made of 1.4301, the sensor is suitable for higher pressures and aggressive media. The reed technology operates without continuous current and ensures durable, interference-free level detection. Installation is horizontal via a G 1/8 internal thread, offering stable, pressure-resistant integration.
