HFD27-012-H Sub Mini DIP Sealed 12VDC DPDT Hi-Sensitive Relay

The HFD27-012-H relay from Hongfa is a compact subminiature DIP sealed relay engineered for low-power, high-sensitivity switching applications. Featuring a Form 2C (DPDT) contact arrangement and a sensitive 12VDC coil with only 150mW power consumption, this relay is ideal for telecommunications equipment, industrial control systems, instrumentation, automation circuits, audio devices, and compact PCB assemblies.

Designed for dependable signal and control switching, the HFD27-012-H supports a maximum switching current of 2A with contact ratings of 1A at 125VAC and 2A at 30VDC. Its gold-plated AgNi contacts provide excellent conductivity, reduced contact resistance, and reliable long-term operation for low-level signal switching applications.

The compact 20.2 × 10 × 11.5mm DIP package allows easy PCB mounting in high-density electronic designs where space-saving and reliability are critical. With epoxy sealing for improved environmental protection and an operating temperature range from -40 C to +85 C, this relay delivers stable performance in demanding conditions.

Fast operate and release times ensure responsive switching performance, while low contact resistance improves signal integrity and efficiency.
