We make high demands on the metal contact surfaces in order to protect connectors against corrosion and environmental influences. Naturally, we use only high-grade copper alloys and Cr(VI)-free processed steel parts.
Tin-plated contact systems are a practical and inexpensive solution for soldering applications.
Tin initiates an intermetallic reaction with base materials, such as brass or bronze. This can lead to increased corrosion. A nickel resistive layer is used in Phoenix Contact products to prevent this reaction.
This means for you:
High level of conductivity at higher currents – you can benefit from this excellent characteristic of silver layers.
Used in our high-current connectors, these surface systems offer the following advantages:
The main advantage of gold layers is their resistance to corrosion in various different aggressive media.
With these characteristics, gold surfaces for voltages < 20 mV and currents < 3 mA are ideal and durable surfaces with > 100 insertion/withdrawal cycles.
Integrated double steel springs provide additional safety in the event of power and temperature fluctuations.
Used in our connectors for high-current applications, the double steel spring offers the following advantages:
