Magnet N-pole and S-pole identification device (Magnetic polarity identification device)
SW-350
You can easily distinguish between the N pole and S pole of a magnet. It is suitable for school science projects. LEDs corresponding to each of the N pole and S pole will light up.
The N and S poles of the magnet can be visually identified. When magnetic fields are detected, the LED lights up red for the N pole and blue for the S pole (when using the DW-350). Additionally, it is equipped with individual transistor outputs, making it easy to apply in circuits. It operates from DC 10V, so power supply using batteries in series is also possible. You can use it for various applications, from elementary school experiments to sophisticated control devices, depending on your ideas. *Strong magnets can be obtained at 100 yen shops, so feel free to try various things.

basic information
Model DW-350 (Reference) Power supply DC 10V to 30V (7 AA batteries in series are also OK) Transistor output 2 channels Protection structure IP67 compliant Size M12×4mm, Cable 2m (nut included) *Since the threshold is around 0.5mT, it cannot distinguish between magnets below that level or small magnetic forces such as those from the magnetic stripe of a cash card.
