Correct Use
●Mounting
•When mounting more than two Relays on a PCB, keep the gap as shown in the following figure.
•No specified mounting direction.
•Not compatible with sockets.
•There is the current-carrying metal part on the coil terminal.
Do not mount to the PCB with patterned metal surface.
●Other Precautions
•This Relay is suitable for power load switching of motors, transformers, solenoids, lamps, heaters, etc.
Do not use the G4W to switch micro loads less than 100 mA, such as in signal applications.
