The Wangrong RJE-105DF with Relays General Purpose Non Latching 5VDC SPDT 5A 277VAC Through Hole RoHS is an electrical relay designed for general purpose applications. It has a 5V DC voltage, 5A current, and a SPDT (single-pole double-throw) configuration with 277V AC voltage. It is a non-latching relay, meaning it will switch off when no power is applied. This relay is suited for applications such as motor control, lighting control, signaling, home security, etc. It is through-hole mounted, meaning it can be easily installed on a printed circuit board, and has RoHS compliance.
