2M801 Connectors with Dual-Start Acme Threads

Amphenol® MIL-DTL-38999 Series I Connectors were developed to meet the needs of the aerospace industry and provided the impetus for the development of the MIL-C-38999 specifications, which later was superseded by MIL-DTL-38999. Amphenol’s MIL-DTL-38999 Series I and commercial LJT series connectors meet or exceed the Mil-Spec requirements and are available in aluminum or stainless steel as well as several different finish options.

Part Prefix: MS27*, LJT*, JT

2M805 Tri-Start Threaded Coupling Micro-Miniature Connectors

2M805 micro 38999 connectors are the evolution of the mil-standard circular. Designed to meet the same harsh environmental requirements of D38999, they were developed to make scaling-down existing technology easy and risk-free. Your systems are getting smaller, lighter, and faster; so why wouldn’t your interconnect do the same? Less than half the size and weight of their 38999 predecessors, you can reduce size, reduce space, and reduce cost… but never reduce your expectations.

Benefits

Tri-Start fast coupling
Excellent EMI shielding
Superior vibration resistance
Waterproof
Nickel-plated ground spring
High Speed Options Available

2M803 1/4-Turn Bayonet Coupling Lightweight Connectors

2M803 micro-miniature circular connectors are very light; and their fast, sure-mate bayonet coupling makes them the perfect choice for light-duty applications that require frequent disconnect. Their micro-miniature size and easy decoupling also make them the connector of choice for customers who have hard-to-reach panels. Unlike their other 2M counterparts, 2M803 connectors are not rated for immersion and are recommended for general purpose connections that will not be exposed to the elements for very long.

Benefits

Bayonet Coupling
Quickest turn-mating of the 2M series
1,000 mating cycles
Lightest of the 2M series

2M804 Push-Pull Quick-Disconnect Connectors

2M804 connectors are the most rugged push-pull micro-miniature circular connectors on the market. Designed for use in soldier-worn tactical equipment deployed by the United States military, these connectors were built to perform. Waterproof, dustproof, and highly resistant to EMI interference, these connectors are just as at home on the battlefield as they are in use on C4I and IFE systems. With up to 85 signals, panel-mounting options, and customizable separation forces, there’s no place on land, sea, and air 2M804 can’t go.

Benefits

Push-pull coupling
Excellent EMI shielding
Rated to 38999 immersions
Quick-disconnect

2M Hermetic Micro-Miniature Connectors
