The MC version includes integrated ferrite plates behind the base that compensate for metal interference, delivering up to 16 inches of read range when mounted on a metal surface at least as large as the reader. This makes it the correct choice for metal pedestals, metal enclosures, and pole-mounted installations where the standard MR-1824 would suffer significant read range loss. Dual data output via Wiegand and RS-232 interfaces provides flexible integration with access control panels. An independent external linear regulated DC power supply is required.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine AWID MR-1824MC Sentinel-Prox proximity reader with metal compensation for direct metal surface mounting\u003c\/li\u003e\n\u003cli\u003eUp to 16 in read range on metal surfaces at least 8 x 8 in — correct choice for metal pedestals and enclosures\u003c\/li\u003e\n\u003cli\u003eIntegrated ferrite plates behind base eliminate metal interference without requiring plastic spacers\u003c\/li\u003e\n\u003cli\u003e3-color LED and 4 kHz piezo-electric beeper provide visual and audible feedback controllable by host panel\u003c\/li\u003e\n\u003cli\u003eSelf-testing and self-diagnostic functions confirm correct performance and detect power instability without controller connection\u003c\/li\u003e\n\u003cli\u003eRe-present mode prevents multiple reads from single card presentation\u003c\/li\u003e\n\u003cli\u003eDual simultaneous output via Wiegand and RS-232 serial interface\u003c\/li\u003e\n\u003cli\u003eCompatible with all AWID 125 kHz proximity credentials including clamshell cards, keytags, and adhesive wafers\u003c\/li\u003e\n\u003cli\u003eSuitable for indoor and outdoor installation with minimum IP64-rated housing when exposed to rain or snow\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 1815-284\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e AWID MR-1824MC Sentinel-Prox\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRead Range:\u003c\/strong\u003e Up to 16 in (40 cm) on metal surfaces (varies with mounting, voltage, and credential type)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetal Compensation:\u003c\/strong\u003e Integrated ferrite plates — optimized for metal surfaces at least 8 x 8 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExcitation Frequency:\u003c\/strong\u003e 125 kHz transmit and receive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAntenna Output:\u003c\/strong\u003e Omni-directional low-frequency RF field\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply:\u003c\/strong\u003e +5 VDC to +12 VDC, linear regulated (400 mA at 5V, 1A at 12V) — external supply required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommunication Protocols:\u003c\/strong\u003e Wiegand electrical interface, RS-232 serial interface\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCode Formats:\u003c\/strong\u003e 26-bit to 50-bit AWID credentials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicators:\u003c\/strong\u003e 3-color LED (red-amber-green), 4 kHz piezo-electric beeper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable (Integrated):\u003c\/strong\u003e 10 conductors, 22 gauge, 18 in, overall shielded, gray plastic jacket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable (Wiegand):\u003c\/strong\u003e 4 to 7 conductors, 18 gauge, stranded, shielded, up to 500 ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 8.0 x 8.0 x 1.35 in (20.3 x 20.3 x 3.43 cm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 57 oz (1,617g)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e ABS 2-part enclosure, dark gray, epoxy resin potted electronics, ferrite plates behind base\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Direct metal surface or pedestal using metal-plate adapter and 4 screws through reader cover\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e -31°F to 150°F (-35°C to 65°C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Humidity:\u003c\/strong\u003e 0% to 95% non-condensing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e ISO-9001:2000, FCC Part 15, IC, UL listed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnvironmental Protection:\u003c\/strong\u003e Minimum IP64-rated housing required when exposed to rain or snow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e AWID\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e New, genuine OEM part\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eConclusion\u003c\/h3\u003e\n\u003cp\u003eThe DoorKing 1815-284 AWID MR-1824MC is the correct proximity reader for installations where direct metal surface mounting is required. If mounting on a non-metal surface, the standard MR-1824 (1815-283) is the appropriate choice. Confirm credential compatibility with AWID 125 kHz proximity cards and verify environmental protection and power supply requirements before ordering to ensure proper system integration and long-term reliability.\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003ca class=\"elite-button\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0141\/9617\/8998\/files\/1815-283_specs.pdf\"\u003eCut Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"DoorKing","offers":[{"title":"Default Title","offer_id":40883978403951,"sku":"1815-284","price":744.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0141\/9617\/8998\/files\/1815-284.jpg?v=1753912051","url":"https:\/\/elitegates.net\/products\/doorking-1815-284-awid-proximity-reader-mr-1824mc","provider":"Elite Gates","version":"1.0","type":"link"}
