Features

The EX series relays are the 4th generation from NEC. They are much smaller and lighter weight than previous generations of single/dual relays, yet have a higher capability, and are designed to be lower cost.

The EX2 is a PC-mount, fully-sealed, high-density dual relay consisting of 2 separate 1 form C relays inside one package. If used for reversing motors, the H-Bridge connection is easily done on the PC board, making the EX2 more versatile for when H-bridge is not needed. The EX2 dual relay is intended for automotive loads up to 30A, up to 125° C ambient, and is compatible with pin-in-paste reflow soldering processes.

Ultra Miniature twin relay for high PC board density and reversible motor control
25% less volume and 40% smaller footprint than 3rd generation relays
High performance & productivity by unique symmetrical structure
Flux tight housing
