Overview

The G5V-1-2 DC12 is a compact, SPDT (1 Form C) low-signal relay designed for efficient switching in a through-hole package. It features a high sensitivity 150mW coil that draws only 12.5 mA at 12VDC, making it suitable for logic-level control and telecommunication applications. The fully sealed construction ensures reliability in harsh environments and allows for automatic soldering and cleaning processes.

Why Choose This Part

Its primary advantage is the ultra-miniature size of 12.5mm x 7.5mm, saving significant PCB real estate. The relay provides high sensitivity with a low 150mW power consumption and fast 5ms switching times, while the fully sealed plastic housing offers excellent environmental protection.

Applications

Telecommunication Equipment
Ideal for switching signal lines in networking hardware due to its small footprint and high sensitivity.
Security Systems
Used in alarm control panels and sensor interfaces for reliable contact switching.
Handheld Devices
The ultra-miniature size and low power consumption make it suitable for battery-operated portable instruments.
Industrial Logic Control
Acts as an interface between low-power microcontroller outputs and peripheral loads.

Getting Started

When integrating this relay, ensure the driving transistor or MCU pin can sink the 12.5 mA coil current and always include a flyback diode across the coil pins to prevent inductive spikes. The through-hole package features a standard 2.54mm pitch for easy prototyping on perforated boards or custom PCBs.
