Switchcraft expands the EN3™ Series up to 18 pins. The
EN3™ Series is a popular plastic connector series that meets
a number of harsh weather environmental ratings. It’s now
available from 2 through 18 pins. The 9-18 pin versions are only
available with solder terminals. The solder terminals come in
two styles, straight or staggered. The straight style has equal
length terminals, all facing the same way. The staggered
version has the inner set of terminals longer than the outer set.
Also, the staggered terminals face radially away from the center
of the connector, to make soldering much easier. The 9-18
versions carry the same environmental ratings as the 2-8,
which include IP66/IP68 and NEMA 250, when mated.
