Magnetic proximity switch, N pole/S pole, individual 2 outputs, waterproof, IP-67
Magnetic proximity switch DW-100, DW-350
Magnetic switch (magnetic sensor) using our unique element, different from reed switches, Hall elements, and MR elements, identifies and outputs the N pole and S pole.
There are various detection elements such as reed switches, Hall elements, MR elements, and TMR elements, but our company utilizes a unique "saturable coil" for sensing. Since the outputs are generated separately for the N pole and S pole, the range of applications expands depending on the combination of magnets used. By selecting the appropriate magnets, the detection distance can be extended to over 100mm. It can detect magnets underground. Depending on the application, it can also sense within the soil of golf courses, baseball fields, and various sports venues. For example, if the S pole is detected for positioning, it can decelerate, and if the N pole is detected, it can stop. Normally, it operates under N pole control, and if the S pole is detected, it can perform an unconditional emergency stop, all with a single switch. By using N and S magnets on tags, binary codes can be created, which can also be utilized for sorting tasks. Since it detects the magnetic field generated by the magnets, it is not affected by dirt or dust. Sample lending is available. It can be used in various scenarios, from polarity discrimination of magnets to non-contact detection, from manufacturing lines to inspection jigs. Custom options, such as completely submersible types, are also available while maintaining the electrical specifications.
