5Pcs Black SIP 1A05 Relay Switches 1A NO 4‑Pin Module by Jinshining

Description

Product Overview

The Jinshining 5Pcs Black SIP 1A05 relay set is engineered for dependable performance in demanding industrial and scientific environments. Each relay operates at a nominal 5 V DC supply and supports a continuous current of 1 A, making it suitable for a wide range of low‑power signal switching tasks. The internal reed switch provides a DC resistance between 450 and 550 ohms, ensuring stable contact resistance and predictable behavior over the product’s lifespan. The normally open (NO) contact configuration means the circuit remains open until the relay is energized, offering precise control for applications such as sensor interfacing, indicator lighting, and control logic.

Physically, the relays adopt a compact 4‑pin SIP (Single In‑line Package) footprint measuring just 1 × 1 × 0.2 inches and weighing 1.23 oz, allowing dense placement on printed circuit boards (PCBs). The black housing provides a neutral aesthetic that blends seamlessly with most electronic assemblies while offering protection against electromagnetic interference. The package includes five identical units, giving designers the flexibility to implement multi‑channel switching or maintain spares for future maintenance.

Usage

These relays excel in environments where space is at a premium and reliable switching is essential. Typical use cases include industrial control panels, automation equipment, test and measurement rigs, and hobbyist projects that require precise signal routing. The 5 V operating voltage aligns with common microcontroller platforms such as Arduino, Raspberry Pi, and PLC systems, enabling straightforward integration without the need for additional voltage regulation.

Because the contacts are normally open, the relays are ideal for safety‑critical applications where a circuit must remain inactive until a deliberate command is issued. Examples include emergency stop circuits, interlock systems, and power‑sequencing modules. The low coil current draw also reduces overall power consumption, an important factor in battery‑powered or energy‑efficient designs.

Installation is simplified by the standard 4‑pin layout: two pins for the coil (positive and negative) and two pins for the contact circuit (common and normally open). This configuration allows designers to route power and signal lines cleanly, minimizing cross‑talk and simplifying troubleshooting. The relays can be soldered directly onto a PCB or mounted on a breakout board for prototyping.
