Measuring 0.125 x 0.375 x 0.875 inches, this magnet serves as the actuating half of a two-part reed switch contact set. When aligned with its corresponding reed switch, the magnetic field holds the circuit in its normal state. Displacement beyond the rated gap triggers the switch, signaling an open door or window. Security and alarm technicians install this type of component during new sensor installations or as a direct replacement when the original magnet is lost or damaged.\u003c\/p\u003e\n\u003cp\u003eThis magnet is suited for residential and light commercial security and access control applications. It is typically surface-mounted or recessed into door frames, window sashes, or casings alongside a matching reed switch contact. The compact profile makes it practical for installations where space is limited or where a low-profile appearance is required. Each unit is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCompact rectangular form factor at 0.125 x 0.375 x 0.875 inches for space-constrained installations\u003c\/li\u003e\n  \u003cli\u003eDesigned to actuate reed switch contacts in door and window security sensor assemblies\u003c\/li\u003e\n  \u003cli\u003eSold individually, allowing single-unit replacement without purchasing a full contact set\u003c\/li\u003e\n  \u003cli\u003eSuitable for surface-mount or recessed installation in frames and sashes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement actuating magnet for use with compatible magnetic reed switch contact assemblies in residential and light commercial security sensor applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed security or alarm technicians. Deactivate and disarm the security system before removing or replacing any sensor component. Proper gap alignment between the magnet and the reed switch contact is critical to reliable operation — consult the reed switch manufacturer specifications for maximum allowable separation distance. Secure the magnet with appropriate fasteners or adhesive as specified for the mounting surface type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 0.125 x 0.375 x 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Unit\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: George Risk Industries\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MMF-875\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GEORGE RISK INDUSTRIES INC.","offers":[{"title":"Default Title","offer_id":51690814112050,"sku":"MMF-875","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6bdfa478b7b6ef2f2fdf2c0ea76a138.jpg?v=1788275674","url":"https:\/\/voomisupply.com\/products\/george-risk-industries-mmf-875-replacement-magnet","provider":"Voomi Supply","version":"1.0","type":"link"}
