D2D-1002 is an Omron product in the D2D series of electronic components. It is an electrical relay that utilizes a two-pole, double-throw (DPDT) configuration, with a single pole normally open (SPNO) and a single pole normally closed (SPNC) contact. The rated coil voltage of the D2D-1002 is 5V DC, with a contact rating of 0.3A at 30V DC. The normally open contact is used to turn on an external device, while the normally closed contact turns off the device. The relay has a LED indicator on the PCB that lights up when the coil is energized. It is suitable for low-level circuit construction and switch applications.
