Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

Frequently Asked Questions

Can I use 806-040-ME20QG4STC as a direct replacement for another Glenair Mighty Mouse 806 panel receptacle?
Yes, 806-040-ME20QG4STC can be a practical replacement when the existing design already uses the Mighty Mouse 806 family, but the mating interface, shell size 20-4, keying/orientation C, and 4-position contact arrangement must match the original layout. For 806-040-ME20QG4STC, check panel cutout, flange geometry, and backshell/cable-entry clearance before swapping parts, since even within the same series small mechanical differences can affect fit and cable routing.
What should I verify before selecting 806-040-ME20QG4STC for a new aerospace panel design?
With 806-040-ME20QG4STC, confirm that the panel thickness, mounting flange area, and mating connector orientation fit the enclosure stack-up. Because it is a receptacle with female sockets and solder termination, your assembly process needs access for hand or fixture soldering, and the harness side must be designed to accommodate the threaded coupling and cable opening size of 1.444 in (36.68 mm).
Is 806-040-ME20QG4STC suitable for high-vibration or harsh-environment aerospace assemblies?
806-040-ME20QG4STC is commonly used in aerospace-style interconnect systems, and its threaded coupling, metal shell, and environment-resistant construction support harsh-duty use. In vibration-prone assemblies, the final result depends on proper connector retention, strain relief, and harness support; the connector itself should be combined with cable clamping and routing that prevent torque transfer into the solder joints.
How do I choose the right mating plug for 806-040-ME20QG4STC?
For 806-040-ME20QG4STC, the mating plug must match the Mighty Mouse 806 interface, shell size 20-4, and keying/orientation C. Also verify that the mating side provides the correct contact gender and that the application tolerates the contact arrangement used in this 4-position receptacle. Mechanical compatibility alone is not enough; the wiring scheme and pinout should be checked against the system harness drawing.
Can 806-040-ME20QG4STC be used where EMI shielding is a major concern?
806-040-ME20QG4STC has a metal shell, but the listed construction is unshielded, so it should not be treated as a complete EMI solution by itself. In systems with sensitive signals, use overall cable shielding, proper chassis bonding strategy, and connector-to-panel grounding practices. The integrated ground feature may help with bonding, but the full EMI performance depends on the enclosure and harness implementation.
What are the main design risks when using 806-040-ME20QG4STC with soldered field wiring?
With 806-040-ME20QG4STC, the main risks are solder quality, wire preparation, and thermal stress during assembly. Because the contacts are solder terminations, inconsistent solder fill, excessive heat, or poor strain relief can lead to intermittent connections over time. For long-life assemblies, use controlled soldering procedures, inspection, and wire support to keep movement away from the contact terminations.
Is 806-040-ME20QG4STC a good choice for applications that may need frequent connector mating and unmating?
806-040-ME20QG4STC can be used in serviceable systems, but the suitability depends on how often the interface will be disconnected and reconnected. The gold mating finish on the contacts supports stable contact behavior, yet repeated cycles still require attention to coupling torque, contamination control, and mechanical wear. For maintenance-heavy equipment, confirm the expected mate cycle profile against the system’s service interval.
What should I check if I am migrating from a different circular connector series to 806-040-ME20QG4STC?
When migrating to 806-040-ME20QG4STC, compare more than just the number of positions. Confirm shell size, insert arrangement, orientation C, flange mounting dimensions, panel cutout, contact gender, termination method, and cable opening size. If the previous connector used crimp contacts or a different keying pattern, the harness build, tooling, and mating parts may need to change as well.
Can 806-040-ME20QG4STC be used in high-temperature areas near avionics or power electronics?
806-040-ME20QG4STC is specified for an operating range of -65°C to 175°C, which is compatible with many demanding aerospace and industrial zones. Even so, surrounding materials such as cable jacket, potting, gaskets, and PCB or panel hardware may have lower limits. The connector may handle the local temperature, but the full assembly should be checked as a system.
How do I ensure proper grounding when using 806-040-ME20QG4STC in a metal enclosure?
For 806-040-ME20QG4STC, grounding should be planned through the panel interface and the system bonding scheme, not assumed from the connector body alone. The metal shell and ground feature can support chassis bonding, but the actual electrical path depends on panel finish, mounting hardware, torque, and mating connector construction. If low-impedance grounding is needed, validate continuity after installation.
What packaging or procurement issues should I consider when buying 806-040-ME20QG4STC for production?
806-040-ME20QG4STC is offered in retail package form, so production buyers should confirm unit handling, labeling, traceability, and lot control requirements before release to manufacturing. For aerospace builds, also verify documentation needs, approved vendor status, and whether the procurement flow must support serialization or incoming inspection beyond standard commercial receipt.
Are there any compatibility concerns if I want to use 806-040-ME20QG4STC in a non-aerospace industrial product?
806-040-ME20QG4STC can be used outside aerospace when its size, environment resistance, and coupling style fit the design, but the application must still match the connector’s mechanical and environmental characteristics. Industrial products should evaluate mating access, field assembly method, sealing needs, and cost structure. If the system needs a fully sealed or shielded circular connector, a different connector family may align better with those constraints.
