HALL EFFECT GEAR-TOOTH SENSORS  
–ZERO SPEED  
The A3046EU/LU, A3056EU/LU, and A3058EU/LU Hall effect  
gear-tooth sensors are monolithic integrated circuits that switch in  
response to differential magnetic fields created by ferrous targets.  
These devices are ideal for use in gear-tooth-based speed, position,  
and timing applications and operate down to zero rpm over a wide  
range of air gaps and temperatures. When combined with a back-  
biasing magnet and proper assembly techniques, devices can be  
configured to give 50% duty cycle or to switch on either leading,  
trailing, or both edges of a passing gear tooth or slot.

The six devices differ only in their magnetic switching values and  
operating temperature ranges. The low hysteresis of the A3046/56EU  
and A3046/56LU makes them perfectly suited for ABS (anti-lock brake  
system) or speed sensing applications where maintaining large air  
gaps is important. The A3046EU/LU features improved switch point  
stability with temperature over the A3056EU/LU. The high hysteresis  
of the A3058EU and A3058LU, with their excellent temperature  
stability, makes them especially suited to ignition timing applications  
where switch-point accuracy (and latching requirements) is extremely  
important.
