- What are the key design constraints when integrating the Glenair 806-058-NF24-19S1A into a panel-mounted aerospace application?
- The 806-058-NF24-19S1A is a 19-position circular connector with panel-mount through-hole installation via a flanged design. When integrating this receptacle into aerospace systems, ensure that your PCB or chassis material can accommodate the threaded fastening mechanism and that the panel thickness aligns with the flange geometry. The solder termination requires controlled reflow or hand-soldering conditions to avoid thermal stress on the aluminum shell. Verify that the mounting orientation (Orientation A) matches your harness routing and accessibility requirements, as the connector's threaded coupling means field disconnection will require proper tooling.
- Can the Glenair 806-058-NF24-19S1A handle the full aerospace operating temperature range in mission-critical applications?
- The 806-058-NF24-19S1A is rated for -65°C to 175°C continuous operation, which covers typical aerospace environmental profiles including high-altitude and ground equipment scenarios. The copper alloy contacts with gold mating finish maintain contact resistance stability across this range. However, thermal cycling stress concentration points occur at the solder joints and the aluminum shell-to-insert interface; in systems with frequent temperature cycling, conduct thermal cycling qualification (per MIL-DTL-38999 or equivalent) to confirm solder joint durability and contact retention over the product lifetime.
- What termination challenges should be anticipated when hand-soldering the 806-058-NF24-19S1A, and how does solder joint quality affect connector reliability?
- The 806-058-NF24-19S1A features 19 solder termination points on female sockets, requiring precise wetting and controlled thermal profiles to avoid cold solder joints, bridging, or insufficient fillet formation. Hand-soldering introduces variability; use temperature-controlled irons (350–375°C tip temperature) and lead-free or lead-containing solder per your process specification. Poor wetting or voids at the 806-058-NF24-19S1A termination interface will increase contact resistance and degrade signal integrity in mixed-signal applications. Automated wave or reflow soldering with fixture support is recommended for production volumes to ensure consistent fillet geometry and mechanical strength.
- Is the Glenair 806-058-NF24-19S1A suitable for high-reliability, long-duration space missions, or are there limitations in the material specification?
- The 806-058-NF24-19S1A uses an aluminum shell with olive drab cadmium finish and copper alloy contacts with gold mating surfaces. Cadmium plating is not RoHS-compliant and is restricted under REACH regulations in commercial markets, but it remains acceptable for aerospace applications where outgassing, low-temperature brittleness, and corrosion resistance meet mission requirements. For extended space missions with vacuum outgassing concerns, verify compatibility with your spacecraft's material outgassing limits (ASTM E595 or NASA ASTM E595); if outgassing is a concern, consider alternative connectors with conformal coating or alternative shell finishes. The gold contact finish resists tarnishing in vacuum environments better than unplated copper.
- What are the practical differences between the Glenair 806-058-NF24-19S1A receptacle and competitor 19-position circular connectors such as Amphenol PT-06 or Souriau 81-series alternatives?
- The 806-058-NF24-19S1A (Mighty Mouse 806 series) occupies a mid-range position in the circular connector market. Compared to Amphenol PT-06 series, the 806-058-NF24-19S1A has a smaller shell diameter (24-19 insert), lower mating/unmating force, and lighter weight—advantageous for weight-constrained aerospace platforms. Souriau 81-series connectors offer higher contact density and tighter EMI shielding but at increased cost and panel real estate. The 806-058-NF24-19S1A's threaded coupling (versus bayonet on some alternatives) provides positive locking and is preferred in high-vibration environments. Verify contact current ratings: the 806-058-NF24-19S1A supports military-standard current levels (~5 A per contact typical), adequate for most avionics but insufficient for high-power distribution. If migrating from a competitor connector, re-qualify mating force, contact resistance, and vibration response.
- How should the solder termination of the 806-058-NF24-19S1A be protected from moisture ingress and corrosion in outdoor or maritime aerospace applications?
- The 806-058-NF24-19S1A itself does not include internal potting or conformal coating; the solder joints and internal contact area are exposed to ambient moisture and salt spray in unenclosed designs. In maritime or high-humidity environments, apply conformal coating (acrylic, urethane, or silicone per IPC-A-610) to the solder side of the PCB and around the 806-058-NF24-19S1A termination area. Alternatively, pot the entire connector assembly in epoxy or silicone elastomer, ensuring the epoxy does not block the threaded mating face. The olive drab cadmium shell provides moderate corrosion resistance, but regular maintenance inspections are recommended for long-term outdoor storage. For connectors experiencing continuous salt-spray exposure, consider periodic dielectric testing to confirm coating integrity.
- What are the mating cycle life expectations for the Glenair 806-058-NF24-19S1A, and does the threaded coupling affect durability?
- The 806-058-NF24-19S1A is rated for thousands of mate/demate cycles under normal conditions (MIL-DTL-38999 baseline ~500 cycles minimum); exact cycle life depends on contact wear, mating force application, and connector condition. The threaded coupling mechanism (versus snap-in or bayonet) distributes load more evenly over the shell, reducing shell cracking risk but introducing thread-stripping concerns if excessive torque is applied during mating. Over-torquing the 806-058-NF24-19S1A threaded ring can damage the aluminum shell threads or compress the contact insert prematurely. Establish and train on proper mating torque limits (typically 15–25 in-lb for this class) and inspect thread condition periodically in field-serviceable designs. Contact wear accelerates in high-current applications; measure contact resistance at intervals if the connector is mated/demated frequently.
- Can the Glenair 806-058-NF24-19S1A be used as a direct drop-in replacement for obsolete or end-of-life circular connectors in legacy aerospace systems?
- The 806-058-NF24-19S1A can serve as a replacement connector in many legacy systems, but direct drop-in compatibility is not guaranteed. Verify dimensional compatibility (shell size, flange dimensions, panel cutout) with the legacy connector's mechanical drawings. If the original connector uses a different termination method (crimp vs. solder), you must redesign the harness interface. Contact pin assignments and signal levels must remain compatible; rewiring is often necessary if the legacy connector used a different pin-out standard. Qualification testing (continuity, insulation resistance, voltage withstand, thermal cycling) is mandatory before deploying the 806-058-NF24-19S1A as a replacement in flight-critical systems. The cadmium finish of the 806-058-NF24-19S1A may differ from nickel or tin-plated legacy connectors, affecting mating feel and potential galvanic corrosion if mixed with incompatible metals; isolate dissimilar metals with dielectric or corrosion-inhibiting compounds.
- What shielding and EMI mitigation options are available when using the 806-058-NF24-19S1A in noise-sensitive avionics or RF applications?
- The 806-058-NF24-19S1A does not include integral electromagnetic shielding; the aluminum shell provides minimal RF isolation. In avionics or RF applications, shielding must be implemented externally: route shielded twisted-pair cables to the connector, terminate shield braid to a 360° shield contact or solder directly to the aluminum shell flange with low-inductance straps. The 806-058-NF24-19S1A's female socket arrangement (19 positions) may limit the number of dedicated shield pins available within the connector; reserve positions or use external shielding and grounding tabs. Ensure the shield connection path from the 806-058-NF24-19S1A to the mated plug connector is continuous and low-impedance across the operating frequency range. For high-frequency applications above 1 MHz, conduct emissions testing to confirm the 806-058-NF24-19S1A shielding configuration meets regulatory (DO-160G or equivalent) and system EMC requirements.
- How does the gold contact finish on the Glenair 806-058-NF24-19S1A perform in long-term storage or non-powered standby conditions?
- The gold mating finish on the 806-058-NF24-19S1A contacts resists oxidation and tarnishing during extended storage, preserving low contact resistance when the connector is eventually mated. Gold plating thickness (typically 0.75–2.5 microinches per MIL-DTL-38999) provides adequate corrosion barrier for decades-long shelf life in typical aerospace storage environments. However, if the 806-058-NF24-19S1A is stored in high-humidity or corrosive atmospheres (salt spray, industrial gas exposure), the underlying copper alloy contact material can corrode at the plating edges or in micro-cracks, leading to contact resistance rise. Store the connector in sealed, desiccant-controlled packaging; inspect connectors periodically during long-term storage (annually recommended) for any surface discoloration or deposit formation. Before mating a long-stored 806-058-NF24-19S1A, measure insulation resistance and perform a visual inspection to confirm no corrosion or debris has accumulated inside the socket cavities.
