George Risk Industries N2020-12WG-W 3/8-Inch Recessed Closed-Loop Magnetic Contact

Monitor the open or closed position of a protected opening with a recessed magnetic contact and matching magnet assembly. George Risk Industries N2020-12WG-W uses a 3/8 in recessed contact format and a closed-loop configuration for alarm and access-control circuits that need a contact state from a door, window, cabinet, or enclosure. The contact body installs out of sight within the opening structure rather than remaining exposed on its surface. An MM-600 rare-earth magnet accompanies the contact. Rare-earth magnetic material provides the magnetic field used by the contact, while the wide-gap configuration accommodates installations where the magnet and contact cannot be positioned at a very tight separation. This makes the assembly relevant when door construction, frame geometry, or mounting depth creates more space between the moving and fixed surfaces than a close-gap arrangement permits. Selection centers on three stated characteristics: the 3/8 in recessed size, closed-loop circuit arrangement, and wide-gap pairing with the MM-600 magnet. These details matter when replacing an existing recessed contact or specifying a new monitored opening, because the contact must match the prepared opening and the magnet must suit the available alignment gap. Use it where a concealed magnetic position sensor is required and the installation calls for the supplied rare-earth magnet arrangement.
