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 this connector can be used to retrofit older tethers.
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 [placeholder-12-581] for tips on soldering it successfully.
