RS PRO PCB Signal Relay 12V DC Coil 2A SPDT Sub Miniature HFD23 0476725P

The RS PRO 0476725P PCB signal relay is a high-quality sub miniature relay engineered for demanding applications where board space is limited. With a compact 12.5 x 10 x 7.5 mm footprint, this relay is ideally suited for installation on densely populated printed circuit boards, such as those used in control panels, instrumentation, and industrial electronics. The relay features a 12V DC coil, providing compatibility with low voltage control systems common in automation, signaling, and general-purpose switching.

This model is equipped with a single pole double throw (SPDT) contact arrangement, allowing for versatile switching configurations - making it suitable for signal routing, logic control, and input interface tasks. The maximum switching current of 2A and a power rating of up to 60W ensure safe and reliable operation with various loads, while the maximum switching voltages of 125V AC and 60V DC offer flexibility in both AC and DC circuits.

Reliability is enhanced by gold-plated silver nickel contacts, which minimize contact resistance to 100mΩ and offer outstanding conductivity and corrosion resistance. The relay mounts directly to PCBs via robust PCB terminals and features a coil resistance of 405Ω with a low coil power draw of 50mW, supporting energy efficient operation and high sensitivity within the circuit.

This non-latching relay returns to its initial state after actuation, suitable for applications requiring momentary switching. With an operating temperature range from -30°C to 70°C, it performs reliably in industrial, laboratory, commercial, and signal conditioning environments. The relay also boasts compliance with RoHS, UL, CUL, and CQC standards, assuring safety and regulatory approval across global markets.

Typical applications include keypad and keyboard input circuits, push button interfaces, signal routing in communication devices, and general-purpose switching on control boards. Its sub miniature size and robust construction make it ideal for modern electronic assemblies where compact form factor and reliable performance are required.
