Philips has many applications that must operate in wet or humid environments, often also in contact with organic substances, chemicals, liquids, solid debris. We are looking for connectors that are resistant to electrolytic corrosion or means to turn an existing connector electrolytically corrosion resistant.
The connectors can be of any type, if they are small enough to fit handheld devices, indicatively - fitting within 2 cubic centimeters maximum (plug and socket together), but the smaller - the better.
Means to turn existing connectors electrolytic corrosion resistant could be by means of e.g. mechanical construction, coatings, platings, etc. However, we are open to alternative solutions as well. What is important - both parts of connector shall be protected also when disconnected one from another.

The ideal solution we are looking for is a connector that fits in our handheld devices and is electrolitically corrosion resistant OR hydrophobic OR protected from water ingress, as both latter options prevent water from entering the connector and thereby prevent electrolytic corrosion.Size matters, connectors shall fit, amongst others, also in our handheld devices. Obviously also cost is important as the volumes of connectors used on annual basis is high.
In terms of technical requirements, we are looking for connectors that can transfer power as well as data at the same time. Regarding data, of interest are solutions serving bandwidths from 500 kbit/s to 200 Mbit/s and over, the higher the better; regarding power - from 500mW to 10W and over (at low voltages approx. 3-12 V). For lower spec. of bandwidth, 2 contacts are sufficient, for higher data spec., 4 contacts would be preferred (for the sake of versatility and separation of power and data lines). Solutions based on industry standards, e.g. USB-C are also acceptable. Maximum contact resistance foreseen is 100 mΩ. In addition to the abovementioned requirements, the connector should remain electrolitically corrosion resistant for 100-800 hours and 100-200 connect/disconnect cycles.
As mentioned, a second best option are solutions that can turn an existing connector into a electrolytic corrosion resistant connector OR hydrophopbic OR water-ingress-protected. Options include, but are not limited to, mechanical means to seal the connector (both parts and also when they are disconnected), (hydrophobic) coatings or platings for the contact pins etc. In the case of a hydrophobic coating, the receding contact angle should be above 90°. The resulting connector should be able to withstand the same conditions as the connectors mentioned before.
