WHY DIODES – SENSORS2
Why DIODES
Highly
Integrated
Small and
Low-Profile
Sensors
Innovative Product Solutions
Product Flexibility
Unipolar
Output switches on with a single pole (either N or S)
Returns to its default state when the field is removed
Wide range of output options
Omnipolar
Output switches on with either a N or S pole
Returns to its default state when the field is removed
Wide range of operating switch points (magnetic thresholds)
Latched
Output switches on with either a N or S pole
Output held until opposite pole detected
Wide operating voltage and temperature ranges
Optimized for low current applications
Programmable switch point and operation
Ultra small SMD to through hole package options
System Stability and Reliability
Temperature supply and load stability
Special function
AMR sensors
Nickel temperature sensors
High
