AC5NSDC12V 12V Relay — 5A, 4Pin, 10Pack A compact, reliable 12V DC relay suitable for lowvoltage switching and generalpurpose control applications. The AC5NSDC12V (also listed as AC5N S DC12V or AC5NSDC12V) provides a simple way to switch loads up to 5A using a 12V DC control signal. Sold as a pack of 10 pieces for repairs, prototyping, and small production runs. Key benefits Reliable switching for lowpower loads: 5A contact rating supports a wide range of small loads without overspecifying expensive components. Simple integration: 4pin layout keeps wiring straightforward for control panels, modules, and small circuits. Costeffective spare pack: 10 identical relays let you multiple units or stock up for projects and maintenance. Main specifications Model: AC5NSDC12V (also appears as AC5N S DC12V, AC5NSDC12V) Coil voltage: 12V DC Contact rating: 5A Pin count: 4 pins Quantity: 10 pieces What it does and how it helps Converts a 12V DC control signal into on/off switching of a separate circuit, isolating control electronics from switched loads. Ideal for applications where space and simplicity matter; the 4pin design reduces wiring complexity. Provides an affordable and repeatable switching solution for hobbyists, technicians, and smallscale manufacturers. Compatibility and installation notes Designed for use with 12V DC control circuits. Use an appropriate driver or transistor when controlling the relay from lowcurrent sources such as microcontroller pins. Works well in prototyping, panelmounted control modules, and replacement applications where a compact 4pin relay is required. Ensure load current and type are within the 5A contact rating, and observe safe wiring and protection practices (fuse, flyback diode for inductive loads, etc.). Typical use cases Home automation and lighting: switch LED strips, relays for lighting circuits, or other household lowpower devices controlled by a 12V automation system. Electronics projects and prototypes: control small motors, solenoids, or external circuits from microcontrollerbased boards when used with a proper driver. Security and alarm systems: switch sensors, indicators, or auxiliary circuits in 12V control panels.
