Overview

SS30AT Hall-effect digital position sensor IC, bipolar, SOT-23, pocket tape and reel, 3000 units/reel.

The SS30AT is a versatile, bipolar, Hall-effect sensor. These sensitive magnetic sensors offer reverse polarity protection and deliver stable output over a -40°C to 125°C [-40°F to 257°F] temperature range. Operation from any dc supply voltage from 4.5 Vdc to 24.0 Vdc. These sensors have been designed with the latest technologies to provide reliable, cost-effective solutions to many commercial, medical, and /or consumer applications requiring motor control and RPM sensing. Mounts directly on the electrical traces of a PCB.
