GST18 Compact Connectors

The GST18 is a pluggable device connector for use in lighting and other factory-assembled equipment. Mechanical and color coding provides for a safe and easy separation of different applications, virtually eliminating mis-mating errors. An IP20 touch-safe design, a leading earth contact and an optional locking device all contribute to ensure the safest possible connections.
