中文简体4.1-9.5 Bulkhead Mount RF Coaxial Connectors Manufacturer
Product Overview
Bulkhead mount connectors are designed to pass an RF signal through a panel or wall, creating a feed-through point that separates two compartments or environments. The 4.1-9.5 bulkhead mount series from Yangzhou Jingcheng Electronics achieves this with a threaded barrel body that installs through a standard chassis cutout and is secured with a lock nut on the reverse side — a fast, tool-accessible installation that requires no special equipment. Our bulkhead connectors are available in jam-nut, hex-nut, and round-nut configurations, with and without cable termination on the rear port, and can serve as the interface between an internal cable assembly and an external cable run.
Key Features
Standard threaded barrel allows installation through industry-standard 4.1-9.5 chassis hole cutout — direct replacement for installed base connectors
Jam-nut, hex-nut, and round-nut locking options to suit different panel thickness ranges and torque requirements
Front and rear mating interface ensures universal interoperability with compatible mating connectors
High-cycle mating durability: connector plating and contact spring geometry engineered for hundreds of mating cycles
Available with solder, crimp, and clamp cable termination options on the cable-side port
Passivation-treated stainless steel body as standard for outdoor installations; electroless nickel or gold plating on request
Low contact resistance achieved through controlled plating thickness and precision spring contact design
IP67 sealing achievable with optional O-ring kits, suitable for exposed outdoor installation points

FAQ
Q: What panel thickness range do your bulkhead connectors support?
A: Standard configurations support panel thicknesses up to 3 mm for sheet metal/PCB and up to 6 mm for thicker panels. Custom thread lengths are available for non-standard requirements.
Q: How do you prevent galvanic corrosion between the connector body and aluminum enclosures?
A: We supply stainless steel bodies as standard to minimize galvanic potential with aluminum. For enhanced protection, conductive finishes or pre-applied anti-corrosion grease are available as options.
Q: Are your bulkhead connectors compatible with existing 4.1-9.5 hardware from other manufacturers?
A: Yes. The interface dimensions are verified to ensure full mechanical and electrical interoperability with all compatible 4.1-9.5 mating connectors in the field.
