Protective covers & custom options
Dustproof covers and OEM options for metal USB panel connectors.
After choosing an M22 or M28 connector, define the protective cover, housing appearance, aperture color, rear-side fit and cable harness details here.
Protective covers
Specify the cover after the connector family is selected.
Protective covers are options for M22 and M28 panel connectors. Define them before sampling when the port is exposed to dust, splash, handling or outdoor use.
Dustproof or waterproof protection.
NBR dustproof and waterproof cover options help protect exposed service ports in dusty, outdoor or mobile environments.
Housing material and finish.
304 stainless steel, aluminum alloy and finish references can be discussed when appearance, corrosion resistance or weight matters.
Aperture and visual coding.
Blue is a common aperture reference, while other colors can support brand matching or functional port identification.
OEM cable and routing.
Cable length, rear terminal, wire harness, route direction and termination can be adjusted for equipment assembly.
Option map
Match each custom request to a concrete connector detail.
Use this table to decide what information belongs in the RFQ.
| Option area | What changes | When to request it | RFQ information needed |
|---|---|---|---|
| Protective cover | Dustproof or waterproof cover configuration. | When the connector is exposed to dust, splash, outdoor use or frequent service. | Environment, connection frequency, cover style and sealing expectation. |
| Housing material | Metal material and surface finish. | When appearance, corrosion resistance, weight or equipment grade matters. | Material preference, finish color, application environment. |
| Aperture color | Visible insert or port color. | When ports need brand matching, color coding or product-family consistency. | Target color, reference image, quantity and tolerance expectation. |
| Rear connection | Rear terminal style or direction. | When a standard rear connector does not fit the internal layout. | Rear clearance, PCB position, cable path and preferred terminal. |
| Wire harness | Cable length, termination, direction and assembly package. | When the connector needs to arrive ready for equipment installation. | Drawing, cable length, wire spec, terminal, direction and annual quantity. |
Selection path
Start from the base connector, then add cover and OEM details.
This order keeps the inquiry tied to the correct M22 or M28 model.
Choose family
Start with M22 single-head or M28 dual-head based on mounting size and port density.
Confirm interface
Select USB-A, Type-C, dual-port or mixed layout before custom appearance details.
Resolve installation
Confirm rear connection, panel thickness, rear clearance and cable route direction.
Add OEM details
Specify color, material, cover, harness, sample quantity and expected annual volume.
Option boundaries
What to specify, and what can stay standard?
Standard parts are faster to quote. Custom details need drawings, reference samples or color targets.
| Decision | Prefer standard when | Customize when |
|---|---|---|
| Base connector | A listed M22 or M28 model already matches front and rear layout. | The visible port or rear terminal cannot fit the equipment layout. |
| Color | Default aperture color is acceptable and hidden from end users. | Port color supports product branding, service coding or visual consistency. |
| Cover | The port is protected inside an enclosure or used in clean environments. | The port is exposed to dust, splash, field service or outdoor conditions. |
| Harness | A standard internal cable can be assembled during equipment build. | The connector needs specified cable length, route and termination. |
Sample validation matters
For custom color, cover or harness projects, samples validate fit, appearance, cable route, cover operation and assembly workflow before volume production.
Visual assets
Protective cover and custom option visuals for OEM connector projects.
Connector samples, material storage, rear terminal photos, QC review and packaging images show the actual items reviewed before cover or OEM decisions.
RFQ checklist
Prepare these details for a cover or custom quotation.
The closer the RFQ is to a real drawing or sample, the easier it is to confirm the option.
Closest M22 or M28 reference.
Share the closest catalog model, even if it needs custom changes.
Panel and enclosure details.
Provide panel opening, thickness, rear clearance and cable route direction.
Material, finish and color.
Send material preference, target color and reference photos when appearance matters.
Samples and volume.
Confirm sample quantity, target timeline, annual quantity and packaging requirement.
Cover and custom FAQs
Common questions before requesting an OEM connector quote.
Answers for color, material, cover and harness decisions.
Can the aperture color be changed?
Yes. Blue is a common reference color, but aperture colors can be discussed by project requirement for brand matching or functional coding.
When is 304 stainless steel useful?
Specify 304 stainless steel when the project needs a stronger metal housing reference, improved appearance, corrosion resistance or a more durable exposed panel interface.
What details are needed for OEM customization?
Send the target model, panel drawing, rear connection, cable length, cover requirement, material or finish preference, sample quantity and expected annual volume.
Does customization come before model selection?
No. Choose the closest product family and interface layout first, then define material, cover, cable and color requirements.
