Additional Details

The HFD41-012-H-S operates on a 12VDC coil voltage and has a contact rating of 0.5A at 125VAC or 1A at 30VDC. The 2 Form C (DPDT) contact configuration provides switching of two separate circuits. The sealed construction enhances reliability in harsh environments. Insulation resistance is typically 100MΩ minimum at 500VDC. Dielectric strength is 750VAC between coil and contacts and 500VAC between open contacts. The operating temperature range is typically -40°C to +85°C. The latching feature requires correct polarity for proper operation. The relay is mounted through-hole on PCBs.
