805-003-01NF8-1HB Circular Connector for Rugged Equipment and Cable Assemblies

ElecSuppliers Part Number GuideAug 15, 2026

The 805-003-01NF8-1HB is a specialized connector designed for equipment that requires a secure and dependable electrical connection between a cable assembly and the main system.

Unlike ordinary board connectors, components in this category are selected as part of the complete mechanical and electrical interface. The connector has to match the mating component, contact arrangement, mounting requirements and cable configuration.

For that reason, the complete part number is particularly important when sourcing 805-003-01NF8-1HB.

More Than Just an Electrical Connection

In rugged electronic equipment, a connector has two jobs.

It needs to maintain electrical continuity, but it also needs to remain mechanically secure.

A connector that works perfectly on a laboratory bench may not be suitable for equipment exposed to vibration, repeated movement or demanding operating conditions.

This is where specialized circular connector designs become useful. The mechanical connection becomes part of the overall reliability of the equipment.

805-003-01NF8-1HB in Cable Assemblies

One practical use for a connector such as 805-003-01NF8-1HB is cable harness construction.

Instead of permanently wiring individual conductors into equipment, a removable connector provides a defined interface between the equipment and its harness.

This makes installation easier and can also simplify maintenance.

A technician can disconnect the harness from the equipment without having to remove individual wires from terminals or open up the entire electrical assembly.

Why the Complete Part Number Matters

The long designation 805-003-01NF8-1HB is not something that should normally be shortened when ordering.

Connector families often contain many visually similar products. Small differences in contact configuration, mounting style, keying or termination can determine whether two parts can actually be used together.

A generic search for "rugged circular connector" may therefore produce thousands of components that have no direct compatibility with the original part.

Using the complete MPN greatly reduces this problem.

Suitable for Demanding Electronics

The connector can be considered for equipment where reliability of the external electrical interface is important.

Potential application areas include:

• Aerospace equipment

• Military electronics

• Industrial systems

• Transportation equipment

• Test equipment

• Communication hardware

• Rugged instrumentation

• Custom cable assemblies

The final application should always be evaluated against the connector's complete mechanical and electrical specifications.

Connector Selection Starts With the Mating Part

When replacing 805-003-01NF8-1HB, the mating connector should be identified before ordering a substitute.

This is especially important for specialized connectors.

Two connectors can have similar dimensions while using different contact layouts or mechanical keying. A replacement that cannot mate correctly is of little use even if its electrical ratings appear suitable.

For existing equipment, checking the original connector and its mating half is therefore one of the first steps in the sourcing process.

Mechanical Design Can Be Just as Important

A connector is part of the physical structure of a product.

The mounting method affects how forces from the cable are transferred to the equipment enclosure. Cable routing, strain relief and connector orientation can also affect long-term reliability.

This is particularly relevant when the product is expected to experience vibration or frequent servicing.

For 805-003-01NF8-1HB, the mechanical characteristics should therefore be considered together with the electrical requirements rather than treating the component as simply another plug or socket.

Finding a Replacement for 805-003-01NF8-1HB

A suitable replacement should match the original connector as closely as possible.

Important points to compare include:

Contact arrangement

Mating configuration

Mounting style

Termination method

Keying and orientation

Environmental requirements

Cable compatibility

Even one difference can prevent a replacement from being used directly in an existing harness.

805-003-01NF8-1HB Supplier Search

For procurement, 805-003-01NF8-1HB should be searched as the complete part number.

This is much more precise than searching for a general rugged connector because the long MPN identifies the particular configuration required by the design.

When requesting a quotation, provide the complete MPN and confirm the exact connector configuration with the supplier.

For equipment that relies on a reliable rugged cable interface, 805-003-01NF8-1HB is best treated as a specific connector assembly component rather than a generic interchangeable connector.
