Excellent Circular Metal-Shell Connectors

INTE-AUTO knows the importance of the outer shell. That’s why we use only the best materials (brass alloy), ergonomic designs, and the best-proven latching mechanism (push pull mechanism).

This is to provide the highest quality circular metal outer shell connectors to all our customers.

Our circular metal shells pass the highest standards, ensuring over 5000 mating cycles, protection against extreme temperatures, and resistance to high vibration, shock, and salt spray.

Despite all these features, INTE-AUTO’s connectors have the best prices in the market today.

Precison & Lightweight Circular Metal Outer Shell Connectors

The outer shell of a connector is critical in protecting connections. This casing houses the push pull mechanism that allows for an easy yet strong and secure connection. The outshell also allows for ergonomics, that is, it makes handling and operating the connector easier.

INTE-AUTO uses brass as its primary outer shell material because it exhibits the properties that are most desirable for electrical connectors: low conductivity and toughness. The strength and ruggedness of the alloy make our circular connectors fit for extreme environments and rough handling. 

The outshell can endure at least 5000 mating cycles, up to 95% humidity, 250°C heat, 15 g[10 HZ-2000HZ] vibration, 100g of shock, and over 48 hours of salt spray. It has 360° EMC shielding and a rating of IP50 to IP68.

More than that, it houses the push pull latching mechanism perfectly. These rugged connectors come in a wide range of sizes and can be used as substitutes for other existing brands in use.

Aside from function and protection, our connectors sport an elegant pearl chrome or black chrome finish.
