A built-in regulator provides stable operation over 4.5 Vdc to 24 Vdc supply voltage range, and internal circuitry prevents sensor damage in case the supply voltage polarity is accidentally reversed. The SS41 Series Bipolar Hall-effect sensors are small, versatile digital Hall-effect devices that are operated by the magnetic field from a permanent magnet or an electromagnet. The open-collector sinking output voltage is easily interfaced w ith a w ide variety of electronic circuits. NOTE: These digital Hall sensors have an operating temperature range of -40 C to 125 C [-40 F to 257 F], appropriate for commercial, consumer, and industrial environments.
