Tiny, unique, 3 lead semiconductor device can be connected to a simple 1 transistor circuit to operate a LED or close relay contacts when a magnet is brought near it. When the magnet is flipped over (change poles) and brought near the sensor-the relay contacts will open or the LED will go off. These are brand new and we include in each package of Hall Effect sensors a schematic of the hookup of a one transistor driven circuit described above. The Hall Effect sensors are about half the size of a T092 transistor and will have several different markings, however they are all basically the same part. Package of 4. G1994
