Compatibility

Description

TX hermetic receptacles are made from stainless steel and glass-fused inserts to create an airtight seal. They are compatible with all D38999 plugs. The hermetic box mount receptacle features a low-profile design that does not permit the use of backshells, making it ideal for confined spaces. A gasket and a mounting bracket with sealing screws are recommended for a reliable hermetic seal.

Compatibility

Description

D38999 style jam nut receptacles are preferred for hermetic applications because of their single mounting hole design and the integrated O-ring that seals the mounting location. A protective cover is recommended when the connector is not in use. The low-profile rear design does not permit the use of a backshell.

Compatibility

Description

The hermetic solder mount receptacle has the smallest mounting footprint available. The reduced flange is useful when soldering in high densities to a panel or mounting to compact probes or sensors. The low-profile rear design does not permit the use of a backshell. Compatible with all D38999 plugs.

Compatibility

Description

Connector savers are designed to protect D38999 connectors that are subject to repeated mating and unmating cycles during manufacturing. Connector savers prevent costly repair or replacement of expensive connectors while preserving the quality and integrity of the connector by absorbing connect and disconnect abuse.

Compatibility

Description

This connector has receptacles on both sides of the shell, allowing D38999 style cable plugs to connect from each side. The pins and sockets can be arranged on either side to meet your design requirements. A mounting bracket and gasket are recommended.

Compatibility

Description

This D38999 style jam nut receptacle offers engineers the unique options of a connector with an airtight hermetic seal and dual receptacle ends to enable bulkhead feed-thru of cables. Protective covers are recommended when the connector is not in use.

Compatibility

Description

Protect D38999 connectors by providing strain relief from the cable or wire bundle. Strain relief backshells are available in straight or 90° configurations. The self-locking option is recommended for high-vibration applications. Strain relief backshells should only be used in clean, dry applications. For complete protection, upgrade to a D38999 compatible EMI/RFI environmental backshell or shrink boot.

Compatibility

Description

These D38999 style composite backshells offer the same protection as metal backshells while also providing a significant savings in design weight. The backshells are available in straight and 90° configurations and feature strain relief cable clamps, environmental sealing rated to IP67, and 360° shield termination hardware. They provide complete EMI/RFI and environmental protection for all mission-critical designs.

Compatibility

Description

The EMI/RFI environmental backshell is the best choice for all applications that demand the ultimate in protection from water, dirt, dust, and moisture, as well as protection from EMI/RFI interference. Sizes are available for all D38999 connectors. For proper sealing, please order the clamp size best suited to fit your outside cable diameter.

Compatibility

Description

Get the best environmental protection against dirt, dust, water, and moisture, as well as EMI/RFI interference protection along with angled cable management for confined spaces. Compatible with all D38999 connectors. For proper sealing, please order the clamp size best suited to fit your outside cable diameter.

Compatibility

Description

A 90° backshell provides D38999 style connectors with the ultimate in protection against environmental hazards and EMI/RFI interference. The angle makes cable management in confined spaces easy. For proper sealing, please order the clamp size best suited to fit your outside cable diameter.

Compatibility

Description

The shorting cap backshell provides a simple solution for testing D38999 connector applications and system reliability.

Compatibility

Description

A shrink boot provides complete IP67 environmental protection and strain relief. Must be used with a boot adapter. See data sheet for complete sizing information.

Compatibility

A 90° shrink boot offers simple cable management, strain relief, and environmental protection. For proper installation, it must be used with a boot adapter. See data sheet for complete sizing information.

Compatibility

Description

This adapter is specifically designed for D38999 style connectors to enable the use of shrink boots for applications requiring environmental protection in a low-profile design. The adapter can be disconnected from the connector for field inspection without having to remove the shrink boot.

Compatibility

Description

Designed for D38999 connectors, the EMI/RFI banding boot adapter provides effective shield termination for applications using a shrink boot. Shielding is achieved with a band applied by a simple hand tool over a specially designed platform. The overlaying boot ensures strain relief and complete IP67 environmental protection.

Compatibility

Description

Protect your D38999 style connectors and contacts from damage and environmental exposure by covering them when not in use. The inner gasket provides environmental sealing while the wire rope attachment keeps the cover close at hand.

Compatibility

Description
