Filtered MIL SPEC Connectors

Lightning Protection and Transient Suppression buil-in to Circular Connectors

 

 

Unwanted interferences at various frequencies that mix with signals are becoming a major problem to the electronics industry. EMI and RFI can result in havoc within electronic systems and lead to failure of complex and large projects.  Our Filtered Circular Connector components are practical and attractive low cost solutions. They perfectly immunize systems against Radiated Emissions and Susceptibility and protect them against Fast Transients, ESO and Lightning Strikes. These products are used more and more in Space, Aeronautical, Telecom, Ground Control Systems and Medical applications.

 

Perfectly filtering Input/Output (I/O) interfaces of space- sensitive military systems demanding hermetic sealing, these filtered connectors are suitable for extreme environmental conditions. They can also include protective components to ensure transient resistance as well as fast HPM (High Power Microwave) pulse durability.

 

The entire assembly is integrated into a single package, where each contact pin has individual filter with specific type and level. Together with other complying design considerations, the use of these filtered connectors enables modern platforms to meet the following reference standards: MIL-ST0-461, MIL-ST0-1275A, MIL-ST0-704A, RTCA-0O1600.  Each filtering module is integrated into the connector, keeping the connector outer form and size unchanged and preserving system Form, Fit and Function (F3). 0esigned for airborne, marine and ground-controlled portable equipment, this line of products can be used in a broad frequency range of up to 20 GHz.

 

Easy retrofit and upgrade
Available system space is not to be concerned about, as our compact connectors are the same in dimensions as the corresponding unfiltered connectors, allowing for easy retrofit and upgrade.

 

Design  flexibility
Our advanced design technologies enable the introduction of a complete selection of both electrical and mechanical solutions, while extensive knowledge allows us to offer design for and production of filtered versions of most connector types.

 

Reduced cost and lead times
With most standard contact arrangement designs, we can reduce the procurement costs and minimize the tooling expenses, down to zero. Moreover, we offer small quantities and prototypes.

 

Weight and space savings
As the filtering elements are placed within the connectors, functional PCB area is kept minimal, and up to 72% of weight is saved compared to the standard configuration of a connector and separate discreet filtering components.

 

 

Filtered MIL-C-38999 Series I

Filtered Mil-C38999 Series I Connectors

These general purpose connectors are used for high density applications. They are available in shell sizes 9 through 25 with up to 128 contacts of size 22 and mixed contact arrangements.

 

The MIL-C-38999 family is offered in a variety of receptacle mounting configurations. These include square flange receptacles for wall and box mounting and jam nut receptacles.

 

Series I connectors are available in a broad range of shell materials and finishes. Aluminum shells have finishes of bright cadmium, olive drab cadmium or electroless nickel. Olive drab cadmium finish is applied over a nickel under plate to create salt spray exposure durability.


These connectors can mate with non-filtered connectors and are drop-in replacements for non- filtered connectors.

 

Filtered MIL-C-38999 Series II

Filtered Mil-C38999 Series I Connectors

Filtered MIL-C-38999 Series III

Filtered Mil-C38999 Series III Connectors

Series III provides an improved threaded connector with a quick disconnect feature of a bayonet connector. In addition, Series III is designed to withstand extreme environmental conditions of e.g. vibration, shock, fluid, sand dust and salt, encountered mainly in modern aircraft wheel wells, engine compartments and wing tips.

 

Series III connectors also include a ratcheting self-locking device which eliminates the need for safety wiring.  These connectors are offered with 22, 20, 16, 12, 8 size contacts, and shell sizes of 9 through  25. Pin count up to 128 pins.These connectors are offered in square flange and jam nut mount receptacles.

Series III connectors are available in a broad range of shell materials and finishes. Aluminum shells have finishes of olive drab, cadmium or electroless nickel.
Stainless steel shells are passivated and nickel deposit finished. Zinc cobalt finishes are also available.

 

We can offer filtered solutions for MIL-C-38999 III connectors which include Fiber-Optics, Coax & Twinax contacts.  These connectors can mate with non-filtered connectors and are drop-in replacements for non-filtered connectors.
