Background

BNC connectors remain a widely used RF interface in test equipment, industrial communication systems, and instrumentation. For vertical PCB-mounted, panel-installed BNC jacks, TE Connectivity’s 1-1337541-0 is a well-known reference design. However, for cost-sensitive projects or volume production, connector pricing and supply flexibility are becoming increasingly important considerations.

Overview of TE Connectivity 1-1337541-0

The TE 1-1337541-0 is a 50 Ω BNC insulated straight PCB socket designed for cable-to-board applications. It features:

Vertical PCB mounting with through-hole soldering

Panel mount with rear installation and hex nut fixation

Bayonet coupling mechanism

Operating frequency up to 4 GHz

Zinc alloy body with nickel plating and gold-plated center contact

This configuration makes it suitable for RF signal transmission in commercial and industrial environments where stable mechanical fixation and reliable impedance control are required.

Introducing Kinghelm KH-BNC50-3511

KH-BNC50-3511 from Kinghelm is designed as a practical and economical alternative for the same application category. It is a 50 Ω vertical BNC jack connector intended for PCB mounting and panel installation, supporting common cable-to-board RF designs.

Key characteristics include:

BNC jack interface with bayonet coupling

50 Ω impedance for RF signal integrity

Vertical PCB mount with through-hole termination

Panel mount structure with hex nut fixation

Frequency range from DC to 3 GHz

Wide operating temperature range from −55 °C to +155 °C

RoHS-compliant materials

In typical industrial, instrumentation, and general RF signal applications below 3 GHz, KH-BNC50-3511 provides stable electrical and mechanical performance comparable to mainstream BNC solutions.

Cost Advantage in Volume Production

One of the most significant differences lies in cost efficiency. Based on distributor pricing, KH-BNC50-3511 offers a substantially lower unit cost, especially as quantities increase. This makes it particularly attractive for:

Cost-sensitive product designs

Medium- to high-volume manufacturing

Projects requiring long-term supply stability

Lower connector cost can help engineers and purchasing teams reduce overall BOM expenses without changing the interface type or mechanical installation concept.

Typical Applications

KH-BNC50-3511 is suitable for a wide range of applications, including:

Test and measurement instruments

Industrial communication equipment

Signal monitoring and data acquisition systems

RF modules and control boards

General-purpose RF signal interfaces
