HFD2/005-S-L2-D 5V Dual Coil Bistable Latching Relay DPDT 2A 30VDC 1A 125VAC

Designing energy-efficient microcontrollers, battery-powered electronics, or automated switching circuits shouldn't mean wasting continuous power just to hold a relay in position. Designed for electronics engineers, IoT developers, and PCB circuit designers, this 5V bistable latching relay HFD2/005-S-L2-D provides dual-coil latching switching performance with zero holding power draw. Standard non-latching relays require continuous current to keep contacts closed, draining batteries rapidly and generating unwanted circuit board heat. Crafted with high-sensitivity dual-coil actuation and gold-overlay silver alloy contacts, this DPDT signal relay toggles state with a brief voltage pulse and holds its position mechanically. Maximize battery life, reduce thermal dissipation on control boards, and maintain critical circuit states even through power outages.

Key Features

• Energy-Efficient Latching Mechanism: Dual-coil bistable design requires only a momentary 5V pulse to switch states, consuming zero power while holding position.

• DPDT Contact Configuration: Double-Pole Double-Throw setup allows simultaneous control of two independent electrical circuits.

• High-Sensitivity Gold-Plated Contacts: Silver alloy contacts with gold overlay ensure low contact resistance and reliable switching for small signals.

• Compact Subminiature DIP Layout: Standard dual in-line package pins fit easily into prototype breadboards and standard PCB layouts.

• Wide Switching Range: Safely handles signal and power switching loads up to 2A at 30V DC and 1A at 125V AC.

Why Choose Our HFD2/005-S-L2-D Bistable Latching Relay Unlike standard relays that constantly draw power and heat up surrounding PCB components, this dual-coil latching relay latches magnetically into place. This makes it ideal for remote IoT sensors, portable battery gear, and memory-retention switching applications where power conservation is paramount. Keep your electronics running cooler, longer, and more efficiently.
