1. Product Features & Specifications

The Kinghelm KH-DC-016-2.5 is a DC power jack tailored for general-purpose electronic devices. Each unit weighs 1.728g and is packaged in bulk, allowing for efficient inventory and transportation. Key specifications include:

lContact Dimensions: 2.5mm inner diameter, compatible with standard DC plugs, enabling higher current density and lower contact resistance.

lElectrical Ratings: 500mA current and 30V voltage ratings, suitable for low-power electronic applications.

lMounting Method: Vertical through-hole pin design, directly inserted into the PCB, simplifying the soldering process and enhancing assembly efficiency.

2. Advantages of Vertical Mount Design

Unlike right-angle jacks, the KH-DC-016-2.5 DC power jack features a vertical mount design with several benefits:

lSimplified PCB Layout: Vertical installation reduces lateral space usage, ideal for height-sensitive compact devices.

lEnhanced Mechanical Strength: Direct through-hole mounting provides better vibration resistance, making it suitable for automotive and industrial applications.

lImproved Compatibility: Supports quick plug-in/out operations and is compatible with standard DC plugs, lowering the barrier for end users.

Additionally, the contact surfaces are nickel-plated for excellent oxidation resistance and durability under frequent usage.

3. Typical Application Scenarios

Thanks to its stable electrical performance and vertical mounting, the KH-DC-016-2.5 DC power jack is widely used in:

lSecurity Equipment: External power interface for surveillance cameras, access control systems.

lMedical Devices: Power modules for portable blood pressure monitors and handheld diagnostic instruments.

lIndustrial Control: Low-voltage connection ports for PLCs and sensor modules.

lConsumer Electronics: DC power input ports for routers, set-top boxes, and home appliances.

Its 2.5mm contact diameter also allows compatibility with higher-power cables (e.g., some LED lighting devices), expanding its range of applications.

4. Key Competitive Advantages

lHigh Reliability: Tested under 30V/500mA load for long-term stable operation, with contact resistance below industry standards.

lFlexible Integration: Vertical mount design supports multilayer PCB structures, catering to various installation needs.

lEco-Compliant: RoHS-compliant materials and lead-free manufacturing meet global environmental standards.
