Honeywell SS41F

The SS41F and SS41G are small, versatile digital Hall- effect devices that are operated by the magnetic field from a permanent magnet or an electromagnet, and are designed to respond to alternating North and South poles. A built- in regulator provides enhanced stability of operation over 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 SS41F is factory tested at 25°C [77°F] and the SS41G is factory tested at both 25°C [77°F] and 125°C [257°F] Both products are designed for high volume applications. These products are available in one package style: SS41F, SS41G: Flat TO- 92- style package with straight leads in bulk packaging which allows for a compact PC board layout

• Small, leaded, flat TO- 92- style package allows for a compact PCB layout
• Wide operating voltage range of 4.5 Vdc to 24 Vdc allows these sensors to be used in a variety of applications
• Current consumption of only 5 mA max. at 4.5 Vdc for energy efficiency
