• Proximity sensing of Ferrous targets
• Gear tooth sensing
• Speed sensing
• Angular Position sensing
• Linear Position Sensing
DESCRIPTION
The 65035 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.
