Magnetic proximity sensor/switch (DC 3-wire type / rectangular M9 case type)
Magnetic proximity switch SW-250A, SW-270A
【Sample available for loan!】 A unique magnetic switch different from reed switches and Hall elements. Designed for long life and maintenance-free.
This is a DC three-wire magnetic proximity switch using a saturated coil that utilizes high-frequency transmission. We offer four models tailored to different applications based on shape and protective structure. The 'SW-252A' and 'SW-272A', compliant with IP68, can be used underwater at all times. Additionally, leveraging the characteristics of magnetic detection type proximity switches, it allows for the differentiation of detected magnetic poles (both NS poles, only N pole, only S pole). Main Features: Four models available: rectangular case types 'SW-250A' and 'SW-252A', and M9 case types 'SW-270A' and 'SW-272A'. - The 'SW-250A' and 'SW-270A' with protection structure IP67 come with an operation indicator light. - The IP68 'SW-252A' and 'SW-272A' can be used underwater at all times. - Output formats (PNP, NPN) can be selected according to PLC input. - The 'SW-270A' and 'SW-272A' have screw threads on the sensor body, making height adjustment easy after installation! The detection distance can be freely set according to the magnetic force of the magnet, allowing multiple units to be used side by side without mutual interference. *For more details, please download the catalog or contact us.*
