Engineered AgSnO2 Bimetal Contacts: The Solution for High-Reliability Switching

Are you experiencing premature failures in your relays and switches due to contact sticking, arc damage, or material transfer? These issues compromise product reliability and lead to costly field failures. Our Silver Tin Oxide (AgSnO2) bimetal contacts are specifically engineered to overcome these challenges in demanding, high-load electrical applications.

Solution for High Inrush Currents: Superior Anti-Welding

Modern capacitive and inductive loads generate high inrush currents that can cause contacts to weld shut. Our AgSnO2 material features a finely dispersed, refractory tin-oxide matrix within a silver base. This composite structure provides excellent non-sticking electrical contacts, ensuring a clean break even after thousands of high-current cycles.

Solution for Longevity: Exceptional Arc Resistance

Electrical arcing erodes contact surfaces, leading to increased resistance and eventual failure. The tin oxide in our contacts helps to quench arcs quickly, minimizing material erosion and transfer. This results in a significantly longer operational lifespan and consistent performance for your components.

Key Benefits:

• Engineered for applications from 10A to over 100A.
• Maintains low contact resistance over the product lifecycle.
• 100% RoHS and REACH compliant, Cadmium-free for global market access.
