6 Pin Circular Mating Connector Option Boosts AT Circular Series Offering

Durable 6 Pin Circular Mating Connector Joins AT Circular Series

Amphenol Industrial Operations has expanded its robust AT Circular Series with the introduction of a new 6 pin option. Designed for rugged environments and engineered with high-performance AT contact technology, this connector delivers secure, sealed, and efficient connections for industrial and transportation systems. OEMs and engineers can now benefit from a versatile 6 pin configuration built to thrive in harsh conditions.

Introducing Amphenol’s New AT Circular 6 Pin Connector

Amphenol Industrial Operations is proud to announce the expansion of its AT Circular Series with a new 6 pin circular mating connector. This rugged and reliable solution has been engineered to meet the toughest demands of heavy equipment, industrial control systems, and transportation applications. With its robust construction, sealed design, and industry-standard compatibility, this connector is ideal for high-vibration, high-contaminant environments where performance and durability are non-negotiable.

Built for the Harshest Environments

The 6 pin circular mating connector is designed for use in rugged outdoor and industrial environments where exposure to moisture, dust, chemicals, and extreme temperatures is common. Built with a heavy-duty thermoplastic shell and equipped with redundant grommet wire seals, this connector ensures protection against environmental hazards. Its reverse bayonet coupling system offers quick and secure mating and unmating, reducing installation time while improving overall reliability.

Reliable and Consistent Electrical Performance

Engineered to deliver dependable electrical performance, this 6 pin version supports up to 13 amps per contact and withstands dielectric voltages up to 1500V. It features Amphenol’s AT contact system, which includes machined contacts available in nickel and gold plating options to provide superior conductivity. The contact retention system not only ensures a stable connection but also reduces installation errors and long-term maintenance costs.

Flexible Mounting Options with Industry Compatibility

To accommodate diverse application needs, the new 6 pin configuration is available in both square flange and jam nut mounting styles. The square flange receptacle simplifies panel mounting, while the jam nut version allows for secure installation in compact or confined spaces. This flexibility ensures ease of integration into new systems or as a retrofit into legacy designs. An optional strain relief accessory adds mechanical durability, and protective caps with or without lanyards are available to prevent damage when the connector is unmated.

Ideal for OEMs Across Multiple Markets

Amphenol’s AT circular 6 pin expansion is tailored for OEMs and systems engineers working in sectors such as agriculture, construction, mining, industrial automation, energy, marine, and heavy trucking. Its environmental sealing, thermal shock resistance, and vibration performance (up to 20g) make it an excellent fit for mission-critical systems that operate under intense physical stress. From steering control systems and engine sensors to lighting and diagnostics, this connector supports a wide range of applications.

Tested to Industry Standards

The AT Circular Series, now including this 6 pin option, has been thoroughly tested under rigorous conditions. It passes salt spray testing (48 hours, per MIL-STD-1344 Method 1001), thermal shock cycles (-40°C to +125°C), fluid exposure, and physical shock (50g in three planes). With an insulation resistance of 1000 megaohms at 25°C and no evidence of water ingress after submersion, this connector is ready to perform in the harshest operating environments.

Backed by the Amphenol Name and Innovation

As part of Amphenol’s extensive interconnect portfolio, the AT Circular Series continues to set the standard for rugged connector technology. This 6 pin circular mating connector builds on a legacy of trusted performance and proven field reliability. Whether used as a standalone connection point or part of a larger system, it delivers the performance engineers and system integrators can count on.
