military,medical,industrial Connector plating material

military,medical,industrial Connector plating on connectors can ensure connection performance and avoid corrosion, oxidation, etc, especially in harsh environment, military connectors, aerospace connectors and also industrial and medical connectors.

Below is plating material details:

Tin (Sn)

Tin plating type is pre-electroplating, pre-cladding, plating. Tin is soft and anti-corrosion with cheap price. Easy to solder, common thickness is 2~4mm, matte or glossy silvery.

Gold (Au)

The best advantage of gold plating is very soft material, anti-corrosion, insoluble in pure acid, good electroconductivity, but very expensive. So elective gold plating is very popular. Gold plated over nickel, common thickness 0.4~3.5mm.

Palladium (Pd)

Palladium can be applied instead of gold plating sometimes.

Nickel (Ni)

Silvery, electroconductivity and weldability is not good, after painted, it is hard and smooth, can be applied for base plating before gold plating.

Silver (Ag)

Gloss white, soft, good electroconductivity and weldability, but very expensive and silver tarnish quickly.

Copper (Cu)

Connector development trend is miniature, lighter

Unmanned systems, military and commercial avionics systems and welding to install applications require a power and data connector, lighter, smaller, but entrenched military specifications before don't account for the reduced size and weight requirements especially for circular connector connection standard electronic box box or other military equipment.

These military mil specification circular connector to withstand the shock and vibration, salt spray, dust and dirt, and water and humidity, however, a growing number of them is too big, some military smallest platform.

Aviation electronics connector business see system, they see is the big, military circular connector, weigh a lot, military and aerospace applications, quality.
"The military ability of circular connector is really shocked and atmosphere, but you are using too much weight and real estate, in the end who will have to be replaced, you need to design to military standard mil, but how do you change the mil standard?"

Adhesive to the latest generation of unmanned aerial vehicle (uav) as prime example, today's military connector applications, promoting the development of electronic and optical connector technology.

Military optical cable connector

Military optical cable connector is designed for field operations equipments, with bayonet coupling mechanism and mis-operation design, mating type is plug-to-plug, plug-to-receptacle, and receptacle-to-receptacle. Advantages are low connection loss, high reliability, robust, waterproof, anti-dust and can be applied in harsh environment, etc.

Application: military optical fiber communication networks, military computer, airborne equipment, shipboard equipment, optical cable repair system, etc.

Feature:

1.       No need flange or adaptor, fast connection;

2.       With guide pin, avoid mis-operation, high-precision contacts ensured fiber connection precision, compatibility and repeatability;

3.       Outer shell material is all dielectric and high strength composite, light weight, high strength can avoid electro-magnetic induction and protect equipments.

4.       With back shell on plug and receptacle, anti-dust

5.       Standard ceramic pin and outer shell size, suitable for current equipments.
