Hongfa HF49FD-005-1H11TF 5VDC 5A SPST Miniature High Power Relay Hongfa HF49FD-005-1H11TF 5VDC 5A SPST Miniature High Power Relay A relay is an electrically operated switch. It consists of a set of input terminals for single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as making contacts, break contacts or combinations thereof. Relays are the most commonly used switching device in electronics. There are two important parameters of the relay, first is the Trigger Voltage, this is the voltage required to turn on the relay that is to change the contact from Common → NC to Common → NO. Miniature high power relay offers low height, 5A switching capability, 3kV dielectric strength (between coil and contacts), and environmentally friendly product (RoHS Compliant) and meets IEC61131-2 reinforce insulation.
