Composite Thermoplastic Connectors, Backshells, Accessories and Enclosures Product Selection Guide

Composite Connectors, Accessories and Enclosures For general purpose applications, electrical connectors and accessories are conventionally constructed from brass, nickel aluminum bronze, aluminum, stainless steel, and more recently from titanium. For applications where weight savings and advanced corrosion resistance is required, Glenair offers both conductive and non-conductive composite thermoplastics as a major alternative material. Glenair's composite interconnect components are manufactured from high-grade engineering thermoplastics for the toughest application environments. Specifically geared for high-performance air, sea and space applications, Glenair's line of composite interconnect components are ideally suited for systems which require electromagnetic compatibility, reliable environmental protection and long-term durability.

Composite MIL-DTL-38999 Style Fiber Optic Connectors
and MIL-T-29504 Termini
- (Entire Section PDF)
Glenair's close-tolerance MIL-DTL-38999 Series III Style Fiber Optic Connector is built to ensure precise optical alignment of optical fibers. Connector polarization keys and keyways are manufactured to tighter tolerances than required by the MIL-DTL-38999 specification to reduce radial misalignment and insertion loss.

Composite MIL-DTL-5015 Type Harsh-Environment Connectors
- (Entire Section PDF)
Glenair's line of 5015 Type Harsh Environment Connectors are designed to provide outstanding corrosion resistance and rugged performance. These composite thermoplastic plugs and receptacles are ideally suited for severe environments such as geophysical exploration, mining and other settings where resistance to extreme temperatures, salt spray and caustic chemicals is a critical requirement.

Composite RFI/EMI Junction Boxes
- (Entire Section PDF)
Glenair's lightweight/high-strength CostSaver Composite EMI/RFI Junction Boxes are ideally suited for use in harsh environments where resistance to electromagnetic interference, corrosive fluids, high temperatures, shock and vibration is a critical requirement. The boxes are designed to meet the shock and vibration requirements of MIL-S-901D and MIL-STD-167SHIPS. Box materials also meet stringent EMI/RFI/HIRF and indirect lightning strike performance specifications.

Composite Circular Backshells and Connector Accessories
- (Entire Section PDF)
Glenair composite accessories are ideally suited for use in harsh environments where resistance to high temperatures, outgassing, corrosive fluids, fire, shock and vibration is required. Materials include Ultem® 2300 and other glass filled composite thermoplastics. Glenair composite accessories are ASTM E595 space rated, and are qualified to the shock, vibration, thread strength and bend moment requirements of MIL-C-38999 and MIL-C-85049. These materials also meet stringent EMI/RFI/HIRF and indirect lightning strike performance specifications.

Composite RFI/EMI Rectangular Backshells
- (Entire Section PDF)
Glenair's line of rectangular backshells is the largest in the industry. The composite thermoplastic versions shown here provide EMI protection for rectangular connectors used in harsh or severe operating environments. Our D-Subminiature and Micro-D versions are both available in top, side and 45° entry configurations together with the full range of conductive and nonconductive finishes. Jackpost hardware is Cres/Passivated stainless steel. All backshell designs meet the exact dimensional requirements for the specified connector series.

Composite Protective Covers and Stowage Receptacles
- (Entire Section PDF)
Glenair makes a full range of composite plug and receptacle covers for 5015, 28840, 38999 and 83723 series connectors. Protective covers are a critical component in interconnect systems where maintenance and test cycles can lead to damage of exposed connectors. Customers may select from split and solid ring designs equipped with rope, sash and bead style chains made from either nylon or stainless steel. Conductive and nonconductive plating options are available, to match the conductivity and impedance requirements of the application and the connector. All covers meet the intermateability requirements for the specified connector series.

Composite Thru-Box,Panel and Bulkhead Fittings
- (Entire Section PDF)
Glenair manufactures a full spectrum line of feed-through fittings for routing wire and cable into and out of switchgear and other types of junction boxes. The fittings are also ideal for thru-panel and bulkhead applications.
From environmental sealers and EMI/RFI shield terminators to strain reliefs and shrink boot adapters—Glenair has the right feed-through for every application requirement. Our composite thermoplastic designs offer significant weight savings and unlimited corrosion protection. Composite feedthroughs are designed to meet RTCA/DO-160C environmental conditions and physical strength requirements.


Composite PEEK™ Convoluted Tubing and Fittings
- (Entire Section PDF)
Glenair's PEEK™ polymer convoluted tubing (polyetheretherkeytone) provides an extremely rugged, lightweight enclosure for wiring systems deployed in harsh application environments. The crush-resistant material provides exceptional flexibility and crush resistance, and can be combined with Glenair end-fittings and transition-fittings to meet almost any installation configuration. The low-outgassing polymer far out performs other plastics and has a V-O flammability rating down to 0.057 inches without the use of additivesÑmaking PEEK™ tubing an ideal choice for a broad range of aerospace, marine, military and commercial applications.

Composite DuPont™ Aracon® RFI/EMI Braided Shielding and Banding Split-Rings
- (Entire Section PDF)
For many applications, the cable shield is the most important element in controlling EMI. Unfortunately, metal shielding—especially when applied in multiple layers—can be extremely heavy. The opportunity to provide robust EMI shielding at a fraction of the weight is the principal advantage of composite thermoplastic DuPont™ Aracon®Braid.

Tools and Accessories
- (Entire Section PDF)
Glenair addresses interconnect system assembly requirements with a variety of military standard and specialized connector-to-backshell assembly tools, braided shielding banding tools and accessories. Our tool line for composite components includes connector wrenches, as well as universal connector holding tools for production use as well as field maintenance.
