MINI UHF Bulkhead Mount RF Coaxial Connectors Manufacturer

Product Overview
The Mini UHF bulkhead jack connector is a panel-mount solution that provides a permanent interface on enclosures, housings, or panels of wireless communication devices and base stations. Serving as the fixed female port, it mates with cable-mounted male plugs to enable repeated connection and disconnection over its service life. Single-hole nut mounting minimizes the required panel cutout area, making it suitable for compact chassis designs, including mobile radios, outdoor wireless access points, base station enclosures, and IoT gateways.

Key Features
Single-Hole Nut Mounting: Rear hex nut clamps the connector to the panel using standard tools, accommodating a wide range of enclosure wall thicknesses.
Toothed Interlocking Interface: Precision-machined teeth on the jack body interlock with the mating plug, preventing vibration-induced loosening without auxiliary hardware.
50 Ω Controlled Impedance: Optimized dimensions of the center pin, PTFE dielectric, and outer body maintain 50 Ω impedance across DC to 1 GHz for signal integrity.
Versatile Rear Terminations: Available with solder cups for discrete wiring, solder pins for direct through-hole PCB mounting, or crimp sleeves for high-volume cable assembly.
Corrosion-Resistant Plating: Nickel-plated brass body with option for silver or gold-plated center contacts to ensure low contact resistance and long-term oxidation resistance.
Compact Footprint: Conforms to standard Mini UHF dimensions, allowing installation on dense equipment panels where standard N-type or TNC connectors are too large.

Competitive Advantages
Dimensional Interchangeability: Manufactured to standard specifications for direct substitution in existing equipment layouts, eliminating re-qualification costs.
Single-Source Matting Accuracy: Manufactured on unified tooling lines with mating plugs to ensure precise interlocking and eliminate tolerance stacking from mixed-vendor sourcing.
Direct PCB-to-Panel Interface: Solder-pin configurations enable direct board-to-panel RF routing, eliminating internal pigtail cables to reduce bill-of-materials (BOM) costs.
Industrial-Grade Verification: Production batches undergo automated testing and electrical verification on network analyzer instrumentation to ensure consistent quality standards.

Typical Applications
Vehicle-mounted mobile radio and PTT device antenna port panels
Outdoor wireless access point and WLAN equipment enclosure antenna interface
Portable base station and repeater equipment antenna panel connections
IoT gateway and wireless sensor hub device panel antenna ports
Two-way radio charger cradle and base station antenna interface panels
Compact wireless communication module chassis antenna feedthrough

FAQ
Q: What panel thickness range does the standard MINI UHF nut-mount connector accommodate?
A: The standard version accommodates typical enclosure panel thicknesses used in wireless communication equipment. For non-standard panel thicknesses, extended-thread versions are available. Please specify the exact panel thickness (in mm) when ordering to ensure the correct thread engagement length is provided.
Q: Can the MINI UHF bulkhead connector be used outdoors without additional weatherproofing?
A: The connector body and plating are designed for the environmental conditions of compact wireless equipment enclosures. For direct outdoor exposure (rain, UV), the mated connector interface should be protected by the equipment enclosure design or by a weatherproof cover. Jingcheng can advise on weatherproofing options for specific outdoor installation requirements.
Q: Is the end-tooth engagement geometry compatible with all MINI UHF plug sources, or only Jingcheng plugs?
A: Jingcheng's end-tooth geometry is manufactured to the MINI UHF international interchangeability standard, ensuring compatibility with standard MINI UHF plugs from compliant international sources. Non-standard or sub-standard plugs with incorrect tooth geometry may not engage correctly; always verify connector source compliance when mixing connector brands in a system.
Q: What is the recommended mating torque for the MINI UHF threaded coupling?
A: MINI UHF connectors are typically hand-tightened to finger-tight, with a final quarter-turn using a small wrench or pliers where tool access permits. The end-tooth engagement provides anti-rotation locking that maintains the connection once the teeth are engaged; excessive torque beyond firm hand-tight is not required and may damage the plastic insulator components in some plug designs.
Q: Can I source both the MINI UHF bulkhead jack and the mating cable plug from Jingcheng?
A: Yes. Both the bulkhead mount jack (this product) and the flexible cable plug connector are available from Jingcheng's MINI UHF series catalogue. Sourcing the mated pair from the same factory ensures consistent end-tooth engagement geometry and electrical interface performance.

MINI UHF Bulkhead Mount RF Coaxial Connectors Industry knowledge

MINI UHF bulkhead mount RF coaxial connectors are panel-mount connectors that pass a signal path through an equipment enclosure wall, fixed in place by a single mounting hole rather than terminated inline on a cable. Built on the reduced shell dimensions of the MINI UHF series, MINI UHF bulkhead mount RF coaxial connectors keep the same compact footprint while adding a threaded panel nut that carries the mounting load, so the coaxial contact itself is not stressed each time an external cable is connected or removed. Covering a frequency range up to approximately 300MHz, the series is suited to compact radio equipment where an inline connector would not clear the enclosure wall.

Common Types & Characteristics

  • Front-mount bulkhead jack — panel nut and lock washer fasten from the front face of the enclosure
  • Rear-mount bulkhead jack — body passes through from behind the panel, leaving a low-profile front face
  • Solder-cup or solder-tab rear termination, selected according to internal wiring method
  • Gasketed variants with an O-ring or rubber washer at the panel interface for sealed enclosures

Across these types, the panel nut also grounds the connector shell to the enclosure, extending the shielding path from the internal wiring across the panel boundary to the mating cable.

Application Scenarios

  • Chassis feedthroughs on compact radio transceivers and handheld charging docks
  • Portable amplifier and repeater enclosures with limited panel space
  • Marine and outdoor communication devices requiring a sealed panel connection
  • Test fixtures and bench panels where an external cable connects and disconnects frequently

Yangzhou Jingcheng Electronics Co., Ltd manufactures MINI UHF bulkhead mount RF coaxial connectors and matched cable assemblies, supplying radio and communication equipment producers with panel-mount interfaces suited to compact enclosure designs.

Selection Points

Selecting the correct bulkhead variant depends mainly on panel access, sealing needs, and internal wiring method rather than frequency, since most applications fall well within the connector's rated range.

  1. Confirm whether the panel nut needs to be accessed from the front or rear of the enclosure.
  2. Match rear termination — solder cup or solder tab — to the internal wiring already used in the design.
  3. Choose a gasketed variant for enclosures exposed to moisture, dust, or outdoor conditions.
  4. Check panel thickness and hole diameter against the connector's mounting drawing before finalizing tooling.

Comparison with Related Connectors

Compared with inline MINI UHF plugs and with bulkhead versions of standard UHF and BNC series, MINI UHF bulkhead mount RF coaxial connectors keep a smaller panel footprint while covering a comparable frequency range to standard UHF, making the choice largely a matter of available panel space and mounting method rather than electrical performance.

Frequently Asked Questions

What distinguishes a bulkhead mount connector from an inline connector?

A bulkhead mount connector fastens through a single panel hole with a threaded nut, fixing it to the enclosure wall, while an inline connector terminates onto a cable and mates with another connector rather than a panel.

Are MINI UHF bulkhead mount connectors sealed against moisture by default?

Standard versions are not sealed. A gasketed variant with an O-ring or rubber washer at the panel interface is recommended for outdoor, marine, or dust-exposed enclosures.

Can custom panel hole dimensions be accommodated?

Panel thickness, hole diameter, and mounting orientation can be configured to a specific enclosure design, based on the panel drawing or an existing connector sample.
