Electrical connection to a Granzow solenoid valve is via a DIN connector. The connector plugs onto the spades of the coil, and a profile gasket ensures a NEMA 4 water-tight connection.
Granzow offers three types of DIN connectors: cable grip connectors, 1/2" conduit connectors, and a 6-foot power cord connector. This model (009) is a Cable Grip Connector.
