Unlock EH Terminal Connectors 
Reliable Choice for High-Density Connections

          In the core connection scenarios of electronic devices, the stability of terminal connectors directly determines the overall device performance. The EH Series Terminal Connectors from Guangdong DEKE Electric feature a core design with a standard pitch of 2.5mm. With precise parameters and versatile adaptability, they have become the preferred solution in fields such as industrial control and consumer electronics. Below, we provide a true and professional detailed analysis focusing on two core products: EH wire terminals and EH pin headers (straight pins, right-angle pins, and locating right-angle pins.

EH (Wire Terminal）

Core Component for Stable Connection

           As the connecting hub between wires and pin headers, the EH Wire Terminal focuses on three core requirements: low-resistance transmission, easy assembly, and long-lasting durability. Its parameters and performance have all undergone rigorous actual testing and verification.

Rated Specifications:
Supports a rated current of 3A AC/DC and a rated voltage of 250V AC/DC, meeting the needs of most low-voltage and medium-voltage equipment.
Contact Performance:
Maximum contact resistance is only 20mΩ, minimizing signal transmission loss; insulation resistance is no less than 1000MΩ, effectively preventing leakage current.
Material & Craftsmanship:
Terminals are made of high-conductivity tin material, and the housing is constructed from flame-retardant material. Compliant with RoHS environmental standards, ensuring safer operation.
Adaptation Range:
Compatible with 22-32AWG wires and supports conductors with a cross-sectional area of 0.34mm² and below. The crimp-type connection is secure and reliable.

EH2.5（Wire Terminal）Core  Advantage

Reliable Connection:
Equipped with a crimping process and snap-fit design, it resists dislodgement during mating and unmating. Tested to withstand multiple insertion cycles while maintaining stable contact.
Flexible Wiring:
Compatible with PCB boards of 0.8-1.6mm thickness, with 2-15 circuit options available. It meets the requirements of high-density wiring scenarios.
Environmental Adaptability:
Operating temperature range covers -25℃ to +85℃, capable of adapting to the working environments of most indoor and outdoor equipment.

EH (Pin Header）

Precise Adaptation Solution for Versatile Mounting

           As the core component for PCB board terminals, the EH Pin Header offers three types: straight pins, right-angle pins, and locating right-angle pins. It targets to address the needs of different installation layouts while balancing space utilization and connection accuracy.

Structural Specifications:
Features a unified 2.5mm pin pitch. With a mounted height of only 8.1mm and width of 3.8mm, the miniaturized design saves PCB space.
Compatibility Performance:
Perfectly compatible with EH Wire Terminals, supporting the same rated current of 3A and rated voltage of 250V, with consistent transmission performance.
Quality Assurance:
Underwent reliability tests such as salt spray and vibration. Compliant with DEKE Electric’s IATF 16949 and ISO 9001 quality management system standards.

Special Features of the Three Types of

EH2.5 Pin Headers

1. Straight Pin Type: Optimal Choice for Space-Saving in Vertical Layouts

Installation Method: Vertically soldered to the PCB board with straightly extending pins, saving horizontal space.
Application Scenarios: Suitable for scenarios with compact internal equipment space that require vertical mating/unmating of wire terminals, such as small controllers and power modules.
Core Advantages: Uniform force during mating and unmating, high mechanical strength, and resistance to deformation after long-term use.

2.Right-Angle Pin Type: Convenient Choice for Horizontal Wiring

Installation Method: 90° horizontal soldering with pins parallel to the PCB board surface, and the wire terminal connection direction is parallel to the board surface.
Application Scenarios: Suitable for scenarios with limited equipment housing space that require wiring close to the board surface, such as home appliance control boards and industrial sensors.
Core Advantages: Reduces wiring bending, minimizes wire fatigue loss, and facilitates later maintenance and inspection.

3.Locating Right-Angle Pin Type: Ideal Choice for Precise Mating and Error Prevention

Installation Method: A 90° right-angle pin with a locating pin design enables precise positioning during soldering, preventing installation misalignment.
Application Scenarios: Suitable for equipment requiring high mating precision, such as medical instruments and precision testing equipment—scenarios sensitive to connection errors.
Core Advantages: High positioning accuracy, with a foolproof design to prevent reverse insertion, improving assembly efficiency and connection reliability.
