HONGFARELAY HFD27/012-H

The Hongfa HFD27/012-H is a high-sensitivity subminiature signal relay with a 12VDC coil, two DPDT changeover contacts and a contact rating of up to 2A.

Technical description

The H version uses an approximately 0.15W high-sensitivity coil with about 960Ω resistance. It provides bifurcated contacts, an epoxy-sealed enclosure and a DIP layout matching a 16-pin IC socket.

Typical applications

Suitable for telecommunications, audio equipment, measuring instruments, alarm systems, electronic interfaces and circuits requiring low coil consumption.

Compatibility note

The H suffix is critical because it identifies the high-sensitivity version. Before replacement, verify the 12VDC coil, coil resistance, DPDT configuration and pinout. The H version is not electrically identical to the 0.2W S version.
