Additional Details

The HF49FD-024-1H12-30VDC relay operates with a 24VDC coil. Its contact arrangement is typically 1 Form A (SPST-NO - Single Pole Single Throw Normally Open). The '1H12' likely indicates specific contact material or construction details affecting contact resistance and life. The relay is rated for switching voltages up to 30VDC, and the switching current is typically around 1A. The insulation resistance between the coil and contacts is generally very high, often exceeding 10^9 ohms. The operating temperature range is usually between -40°C and +85°C. The subminiature size of the HF49FD series makes it a popular choice for applications where board space is limited but reliable signal switching is required. The Hongfa HF49FD series is known for its consistent performance and long operational life.
