General Description

The A1160 is a unipolar, Hall-effect switch with an externally enabled diagnostic function.

In normal operating mode, the A1160 functions as a standard, unipolar Hall-effect switch.

The output transistor turns on (output signal switches low) in the presence of a sufficient magnetic field (>BOP(max)).
