George Risk Industries MM-10 Rare Earth Magnetic Contact

Product Description

The George Risk Industries MM-10 is a rare earth magnetic contact designed for use in security, access control, and alarm system installations. This compact contact measures 1/4 inch in diameter by 3/4 inch in length and uses a rare earth magnet core to deliver reliable magnetic field strength in a small form factor. The unit is sold individually and is well suited for low-profile door, window, and gate sensor applications where space is limited. Licensed security and alarm technicians are the primary installers of this component.

The MM-10 fits residential and light commercial security applications where a flush-mount or surface-mount magnetic contact is needed. Its small diameter makes it appropriate for narrow door frames, cabinet doors, and similar installations where standard-size contacts would not fit. It falls within the miscellaneous contacts category and is commonly used alongside alarm control panels and magnetic reed switches.

Key Features

• Rare earth magnet core provides strong magnetic field strength relative to its small size
• Compact 1/4 inch diameter form factor suits tight or narrow mounting locations
• 3/4 inch length accommodates flush or near-flush installation depths
• Sold as a single unit for targeted replacement or new installation

Compatibility

Designed as an OEM-style magnetic contact for use in residential and light commercial security and alarm systems requiring a small-diameter rare earth magnetic actuator.

Installation Notes

Installation is typically performed by licensed alarm or low-voltage security technicians in accordance with local codes and NFPA 72 guidelines where applicable. Power down or disarm the alarm control panel before servicing any connected contacts or wiring. Ensure the magnet and reed switch are aligned within the manufacturer-recommended gap distance for reliable activation. Do not over-torque mounting hardware on narrow door frame installations to avoid cracking the frame or shifting alignment.
