Reference Mount Pad
Note: The land pattern is an example. Please evaluate your soldering paste and reflow conditions with the product mounted on your equipment.
Magnetic Field Application Direction
Note: Ensure the sensing direction of the sensor aligns with the applied magnetic field direction.

Magnetic Electric Conversion Characteristic
VOUT level changes based on the applied magnetic field intensity (Positive logic). ON/OFF switching occurs depending on the magnetic field strength.
Timing Diagram
Note 1: The magnetic sensor has an internal intermittent switch circuit. The timing of VOUT change is within the ICC on period. Note 2: Consider the speed of magnetic field change relative to the intermittent operation speed in your design.
Packing Specifications
Form of packing: Tape & reel (180, 3000pcs per reel).
Reflow Condition
Maximum reflow condition: Absolute maximum package peak temperature is 260 for less than 10 seconds. Temperatures in the table/figure are package surface temperatures. Preheating conditions must be within the specified range.
Reliability Test
