Hongfa Europe GMBH PCB Mount Power Relay, 5V dc Coil, 5A Switching Current, SPS The HF49FD/005-1H11TF is part of the Hongfa HF49FD series, which consists of compact, high-sensitivity power relays. It operates using a 5 V DC coil and provides electrical isolation between the control circuit and the load, allowing low-power signals (e.g., from a microcontroller) to switch higher voltages or currents. Key Characteristics Type: Electromagnetic relay (non-latching) Contact Configuration: SPST-NO (1 Form A, normally open) Coil Voltage: 5 V DC Switching Current: up to 5 A Switching Voltage: 250 VAC 30 VDC Mounting Type: Through-hole / PCB mount Size: ~20 × 5 × 12.5 mm (slim design) Coil Power Consumption: ~120 mW (low power) Dielectric Strength: up to 3 kV isolation Functional Overview Uses a coil + mechanical contacts: When 5 V is applied → coil energizes → contacts close When removed → contacts open Provides electrical isolation between: control side (low voltage) load side (higher voltage/current) #Relay
