– and how to prevent them

Technical causes of malfunctions

Most faults with 7-pin plugs are caused by:

• Corrosion at the contact points
• Insufficient strain relief
• Poor sealing
• Low quality plastic

For distributors and OEMs this can lead to:

• Higher service costs
• Warranty claims
• Damage to image

Preventive quality choices

At Proshen® we advise and use, among other things:

• High-quality PA6 plastic or glass-fibre reinforced plastic
• Brass or nickel-plated contacts
• Rubber seals for better protection against moisture
• Strain relief according to automotive standards

We also proactively consider design optimization , so that reliability, safety and cost efficiency are optimally balanced.
