Mini USB waterproof panel connector with Ø20.8 mm D-shaped cutout, female-to-male extension cable, feedthrough and solder-pin options for industrial equipment.
The Mini USB Industrial Waterproof Panel Connector series is designed to integrate a Mini USB data interface into industrial enclosures, control cabinets, instruments, and equipment panels.
It provides a fixed external Mini USB connection point rather than allowing a conventional USB cable or connector to remain loose inside an equipment enclosure.
Two product architectures are available.
Product 1 is a Mini USB panel-mount female-to-male extension cable available in 0.3M, 0.5M, and 1M lengths.
Product 2 is an independent Mini USB panel adapter available in Feedthrough and Solder Pin versions for cable-based or PCB-integrated equipment.
According to both supplied drawings, the panel cutout uses an Ø20.8 mm arc diameter with a 19.40 mm D-shaped anti-rotation width.
Type 1:
Mini USB Waterproof Female-to-Male Panel Extension Cable
Product 1 uses a: Mini USB panel female → captive extension cable → Mini USB male architecture.
The internal Mini USB male plug connects to the host or controller, while the panel-mounted female interface provides external access.
Three standard cable lengths are available: 0.3M / 0.5M / 1M
The supplied drawing specifies:
Arc diameter: Ø20.8 mm D-shaped anti-rotation width: 19.40 mm
The complete D-shaped profile should therefore be used for panel machining.
Type 2
Mini USB Front-Lock Industrial Panel Adapter
Product 2 uses an independent front-lock panel adapter structure without a permanently attached cable.
Two versions are available.
Feedthrough: provides a detachable rear connection for equipment using standard internal Mini USB cabling.
Solder Pin: provides rear terminals for PCB or fixed internal wiring integration.
The supplied panel drawing specifies:
Arc diameter: Ø20.8 mm D-shaped anti-rotation width: 19.40 mm
Product Features
01
Ø20.8 D-Shaped Anti-Rotation Cutout
Both products use an Ø20.8 mm arc with a 19.40 mm D-shaped anti-rotation width to help maintain connector orientation.
02
Multiple Internal Connection Options
The series supports captive-cable, feedthrough, and solder-pin architectures for different equipment designs.
03
Three Standard Extension Cable Lengths
Product 1 is available in 0.3M, 0.5M, and 1M lengths for different internal routing distances.
04
Designed for Industrial Panel Integration
The products are designed around equipment cutout, retention, anti-rotation, and internal routing requirements rather than general desktop USB adaptation.
Product Breakdown
Why Is This Product Needed ?
Mini USB remains useful in many industrial controllers, instruments, data acquisition systems, legacy embedded platforms, and specialized equipment.
The original Mini USB port may be located inside the enclosure, on a PCB edge, or in another location that is difficult to access.
A panel connector relocates this connection to a fixed external position, improving mechanical integration, cable routing, service access, and OEM equipment standardization.
Typical Applications
Industrial Automation and Control Equipment
Test, Measurement, and Instrumentation
Core Performance Advantages
01
Reduced Mechanical Stress on Internal Ports
Routine external mating occurs at the panel interface rather than directly at the internal controller or PCB port.
02
Improved Service Efficiency
Technicians can access the Mini USB connection externally without repeatedly opening the equipment enclosure.
03
Improved Internal Cable Management
Multiple cable lengths and feedthrough/solder-pin options support more organized internal routing.
Frequently Asked Questions
Product FAQ
What Is the Main Difference Between the Two Products ?
Product 1 is a captive Mini USB female-to-male extension cable available in 0.3M, 0.5M, and 1M.
Product 2 is an independent panel adapter available in feedthrough and solder-pin versions.
Is the Cutout Simply a Round Ø20.8 mm Hole ?
No. The 19.40 mm D-shaped anti-rotation flat must also be included.
What Is the Difference Between Feedthrough and Solder Pin ?
Feedthrough is suited to detachable internal USB cabling, while solder-pin versions are intended for PCB or fixed wiring integration.
Are Custom, Wholesale, and OEM Services Available ?
Projects can support custom Mini USB connectors, wholesale waterproof Mini USB connectors, industrial Mini USB connector manufacturing, OEM Mini USB extension cables, and custom solder-pin Mini USB connectors.
