Applying a dielectric synthetic connector grease to electrical connectors gives numerous advantages. Connector grease guards against oxidation, fretting corrosion, contact wear and extends connector functional life. The application of a connector grease can ensure equipment reliability and prevent expensive device warranty costs.
A thin film of lubricant can also reduce electrical mating force by as much as 80 percent. For electronic connectors with dozens or even hundreds of pins or for automotive connectors that are in hard-to-reach places, a low insertion force makes assembly more efficient and ensures solid connections.
Please take a look at the various electrical connector grease related articles below, including test videos, theory and product selection help.
Water ingress protection is one of most common reasons for considering the use of a connector lubricant. The ‘go to’ grease in our range for moisture/water protection is Tribosyn 330. It should be noted that we have a range of connector lubricant products available for other connector problems such as…
One of the most common misconceptions we come across is that some electrical engineers think that using one of our specialist connector lubricants will cause extra circuit resistance/circuit impedance across a connector or circuit – this is not correct! As a number of customers ask this same question about possible…
eBikes are growing in popularity and so is the battery technology associated with these exciting bicycles. Some problems that can occur with eBikes are familiar to electrical engineers/technicians in a number of sectors; electrical connector oxidation, water ingress, contact wear and even the infamous fretting corrosion phenomena. A private customer…
A common question from a customer searching for an electrical connector grease to fix an electrical connector fault that has already occurred is, why not just use a conductive grease to fix the fault? A conductive grease is never recommended to fix an electrical connector problem; a dielectric grease is…
What is fretting corrosion? The symptoms are often thought of as ‘gremlins’ in the circuitry. In automotive and passenger cars, an engine management warning light appearing on the the dashboard can be the result of open circuit resistance, caused by fretting corrosion. The electrical connectors in a vehicle appear static…
A common question from engineers is a concern that an electrical connector grease that contains sulfur will interact with terminal metal plating materials, which could be a risk to continuity. The short answer is yes, our connector greases contain inactive sulfur. But there is a difference between inactive and active…
Silicone oils are dielectric and so is silicone grease, silicone is generally low cost and widely available. However we do not recommend using any silicone based lubricant for use on electrical connectors or contacts. Why is this? It’s a fundamental disagreement in theory between ourselves and other companies that offer…
Electrical connector reliability can be significantly improved by using a gold coating on an electrical contact. When gold is used as a contact interface it can provide a stable contact and offer low contact resistance over a connector functional life. Gold is also thought of as a way to reduce…
Grease does not attract dirt. Grease is not polarised and does not act like a magnet for dirt. Sure, if dirt lands on top of grease it will stick there, but that’s one of the reasons for using a connector grease, as a protective barrier……the grease will protect the contact…
If water penetrates into any area of electrical contact, it is likely to cause a problem and electrical and electronic connectors are no different. Most connectors have some level of protection be that a sealed multi-pin, an IP rated connector or just a cheap terminal block; even spade and bullet…
