It operates as an electromagnetic relay with a 12V DC coil, allowing a small trigger current (from a switch, sensor, or control module) to safely energize and switch a much larger load current — a fundamental building block in automotive wiring, aftermarket electronics, and 12V power control circuits.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eBuilt with an SPDT (Single Pole, Double Throw \/ 1 Form C) contact configuration, this relay provides both normally-open and normally-closed switching paths from a single common terminal, making it versatile for a range of switching applications including headlights, fans, horns, fuel pumps, lighting circuits, and other accessory loads. The contacts are rated for up to 30A at 14VDC, giving it enough switching capacity to handle demanding automotive and industrial loads reliably.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe relay features a compact, fully sealed plastic housing that protects the internal contacts and coil from dust, moisture, and vibration — an important consideration in the harsh, high-vibration environment of a vehicle engine bay or chassis. It includes a metal mounting bracket with a bolt-hole, allowing it to be securely fastened to a vehicle body panel, relay box, or DIN rail bracket, along with standard male spade (quick-connect) terminals for simple, tool-free wiring connections.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003eKey Specifications:\u003c\/h2\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e HKE (Zhejiang HKE)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e CMA31-C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Voltage:\u003c\/strong\u003e DC 12V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Configuration:\u003c\/strong\u003e SPDT \/ 1 Form C (Change-over)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Rating:\u003c\/strong\u003e 30A @ 14VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Material:\u003c\/strong\u003e Silver Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDielectric Strength:\u003c\/strong\u003e 500VAC (1 minute)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical Life:\u003c\/strong\u003e 100,000 operations\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range:\u003c\/strong\u003e -40°C to +85°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Bracket Mount (bolt-hole tab)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Type:\u003c\/strong\u003e Quick-connect spade terminals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 dir=\"ltr\"\u003eApplications:\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cp\u003eAutomotive accessory switching (lights, horns, fans, fuel pumps), power window and central locking systems, motor control circuits, aftermarket 12V electronics, marine and RV wiring, and general-purpose high-current DC switching applications.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003ePackage Includes:\u003c\/h2\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e1 x HKE CMA31-C 12V 30A Automotive Relay\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"digilog.pk","offers":[{"title":"Default Title","offer_id":51846807879958,"sku":"b399","price":250.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/0764\/1366\/files\/HKECMA31-C12V30AAutomotiveRelay.jpg?v=1788942050","url":"https:\/\/digilog.pk\/products\/hke-cma31-c-12v-30a-5-pin-automotive-relay","provider":"digilog.pk","version":"1.0","type":"link"}
