B2B Enquiry:
The 41N Hall Effect Sensor is a unipolar digital magnetic sensor designed to detect the presence of a south-pole magnetic field. With fast switching capability and reliable performance, this sensor outputs a digital HIGH or LOW signal based on the detected field strength, offering a non-contact alternative for speed, proximity, and position sensing applications.
Packaged in a standard TO-92 through-hole case, the 41N sensor operates on a wide voltage range of 3.3V to 24V and is compatible with both microcontrollers and industrial logic circuits. Its low power consumption and fast response time make it ideal for brushless motor control, RPM monitoring, magnetic switches, and automation tasks.
