DESCRIPTION
The 65037 Hall effect stud sensor detects the presence of a ferrous material and provides a switched output. The
sensor switches LOW in the presence of a ferrous target and switches HIGH when the target is removed. The
sensor is built into a threaded stainless steel tube and contains a single element Hall effect IC with an integral
Samarium Cobalt magnet and pole piece to optimize sensor performance. Additional circuitry is added to expand
the operating supply voltage range and provide surge protection against outside induced transcients.

NOTES:
1.
Operating Air Gap is dependant on magnetic properties of target. A high grade A2 steel target was used for datasheet characterization. A high end
magnet incorporated into the target can increase operating Air Gap by a factor of 5 or more.
