EN2 Series Data

Features

The NEC EN2 series relay was the first PC-mount, fully-sealed dual relay available. It leads the industry in quality and power/size density. The EN2 consists of two 1 Form C (SPDT) relays in one unit.

The EN2 is available with interconnections for H-bridge motor drive, or with no interconnects for independent operation. The EN2 is intended for automotive loads up to 35A.

Twin relay for motor reversible control
30% less relay space than 2 conventional relays
High performance & productivity by unique symmetrical structure
Flux tight housing
