PM Series Magnet
The PM series magnet is a high-strength Neodymium magnet securely housed within a stainless-steel socket cap screw, offering a rugged and compact solution for proximity sensing and magnetic triggering applications. Available in both North Pole and South Pole versions, this series provides flexibility for polarity-specific sensing requirements.
Design Notes:
- Gap is from the face of the sensor to the surface of the magnet’s South Pole surface.
- Clear “S” engraving on South Pole variant or “N” for North Pole variant ensures quick visual identification during installation.
- Gaps are calculated and will vary slightly part to part.
- Use non-magnetic mounting hardware when installing.
- Refer to the sensor specifications sheet to determine operate gap range.
- The presence of ferrous metals near the magnet effects field strength at the sensor location.
- The presence of steel, magnets, or electromagnetic fields will affect the operate gap range.
Standards and Certifications
- Polarity Selection: Choose between North or South Pole versions to match sensor orientation or system requirements.
- Engraved Marking: Clear “S” engraving on South Pole variant or “N” for North Pole variant ensures quick visual identification during installation.
- Potted Construction: Magnet is securely embedded within the bolt casing for enhanced durability and environmental protection.
- Compact Integration: Ideal for applications requiring a threaded mounting solution with embedded magnetic functionality.
