Description

These small and versatile digital Hall-effect devices are operated by the magnetic field from a permanent magnet or an electromagnet, and are designed to respond to alternating North and South poles. The built-in regulator provides enhanced stability of operation from 4.5 Vdc to 24 Vdc supply voltage range, and internal circuitry is designed to prevent sensor damage in case the supply voltage polarity is accidentally reversed. The open-collector sinking output voltage is easily interfaced with a wide variety of electronic circuits. The SS41 is tested at both 25°C [77°F] and 125°C [257°F]. For design flexibility,
