Description
The AH1815 Hall-Effect sensor is a small, non-latching, magnetic actuated switch. These can be used to detect the presence of a magnet and are often found in wheel encoders, flow sensors, and other non-contact switches. These operate very similar to a Reed Switch, but are considerably smaller. However, it should be noted that Reed Switches can typically carry more current. This sensor operates on 2.5 – 5.5VDC and consumes just 24uW @ 3V.
If you are looking for a latching version of this Hall-Effect Sensor; we also carry the UL1881 Latching Hall-Effect Sensor.
