George Risk Industries 190-12WG-G 3/4 Inch Recessed Wide-Gap SPDT Door Contact

Monitor the open or closed condition of a steel door with a recessed magnetic contact that keeps the sensing hardware inside the prepared opening. The 3/4 inch format addresses installations using that recessed bore size, while the wide-gap construction supports applications where contact-to-magnet spacing needs more tolerance than a standard-gap arrangement. Its SPDT switching arrangement gives the connected security circuit a changeover contact rather than a single fixed contact state. George Risk Industries 190-12WG-G fits physical-security door monitoring where a flush recessed presentation is required instead of a surface-mounted contact. Specify it for steel-door openings that call for a 3/4 inch recessed device and a wide-gap magnetic interface. The SPDT configuration is material to panel wiring: it provides a common connection and two switched states, allowing the installer to select the circuit behavior required by the connected input. This version is differentiated by the combination of steel-door application, recessed 3/4 inch format, wide-gap operation, and SPDT contact form. Those details should match the door preparation, magnet spacing, and input circuit before installation. It is not described as a surface contact or as a standard-gap device, so substituting another contact style can change both fit and circuit behavior. Use it where these named characteristics are required.
