A1126 Datasheet (Allegro)

Product Features (Datasheet Data) 

The A1126 is a chopper-stabilized omnipolar ultrasensitive Hall-effect switch from Allegro MicroSystems. It supports operation up to 24 V and provides reliable performance across a wide temperature range (–40°C to +150°C). Dynamic offset cancellation ensures low switchpoint drift, superior temperature stability, and insensitivity to physical stress. It is an excellent alternative to reed switches.
