The Binder 770 connector is our standard connector for tether connections above the water. The connectors have 8 pins and are IP67 splashproof when mated, reasonably priced, and compact.
The Binder 770 plug is pre-installed on all Fathom tethers since August 2018, but can be used to retrofit older tethers. The Binder 770 bulkhead can be mounted in a spare hole on the FXTI for your custom connections. A corresponding Binder 770 Plug is required for use.
The connector has a current rating of 2A per pin, is rated for 175V (1750V impulse), can handle >5000 mating cycles, and has gold plated pins.
Please note that the connector requires moderate soldering skills and we highly recommend checking out our guide for tips on soldering it successfully.
