Series GA industrial connectors are high-quality special purpose connectors.

The 15 pole circular connector has a housing made of high strength aluminium magnesium alloy. The contact arrangement is a combination of 4 power contacts and 11 control contacts.
The thermoset contact inserts allow the connector to be used for a wide temperature range. Cable-connecting and flange mount plugs and receptacles with different threads for cable glands are available as stock items. Protection caps are available as accessory. Special variants upon request!

Sealed to IP67/IP69K: The pin contacts and solder cups are moulded watertight in the contact inserts of the receptacles, so that there is no ingress of water even when the connector is unplugged.
The polarized key and keyway construction of the connector prevents the contacts from touching the insulator, thus making possible a “blind” mating of the connector halves. The functional threaded coupling ensures reliable connection.
