A1232 Description
The A1232 is a highly sensitive, temperature-stable magnetic sensing device ideal for use in ring-magnet-based speed and direction systems in harsh automotive and industrial environments. It contains two bipolar, Hall-effect switches precisely arranged 1.63 mm apart. The switch outputs are thus in quadrature when interfaced with the proper ring magnet design.
