HFD27-012-S Subminiature Signal Relay 12VDC DPDT PCB Relay

The HFD27-012-S relay from Hongfa is a compact, high-reliability subminiature signal relay designed for efficient low-power switching in PCB-based electronic systems. Featuring a 12VDC coil and Form 2C (DPDT) contact configuration, it is well-suited for applications in telecommunications equipment, industrial automation, instrumentation systems, consumer electronics, and embedded control circuits.

With a 200mW coil design and 720 coil resistance, this relay provides stable and efficient actuation while maintaining low power consumption. Its compact 20.2 × 10 × 11.5mm footprint makes it ideal for high-density PCB layouts where space efficiency is critical.

The HFD27-012-S supports a maximum switching current of 2A, with electrical ratings of 1A at 125VAC and 2A at 30VDC. Gold-plated AgNi contacts ensure excellent conductivity, reduced contact resistance, and long-term signal stability, especially in low-current switching environments.

With a 1.5KV isolation voltage and UL/CUL/TUV approvals, the relay provides dependable electrical safety and reliable performance in demanding operating conditions.
