Introduction

The EJH-125-01-S-D-SM-LC-39 is a rectangular connector – header male pin which appears mostly in electronic connection applications. This connector has been featured mainly in research and development boards, and is also used in the prototyping stage of manufacturing. The EJH-125-01-S-D-SM-LC-39 in particular has seen applications in fields such as the automotive, energy and medical industries, all of which are highly sensitive and require connectors that guarantee a secure and reliable connection. As such, the performance and design of this particular model are exceptional, meeting strict safety and environmental standards.This article aims to provide an overview of the application fields, construction and working principle of the EJH-125-01-S-D-SM-LC-39 rectangular connector.

Application Field and Performance Specifications

The EJH-125-01-S-D-SM-LC-39 connector is designed for applications within the automotive, energy, and medical sectors, and is built to provide tight, reliable connections. This connector model has several performance specifications that include:

• Superior voltage, current, and power authority
• High resistance to abrasion, vibration, shock, and corrosion
• Splashproof and dust-proof design and configuration
• Safety certification and approval by exceptional governing bodies
• Optimized design for use in tight spaces
• A wide variety of custom and off the shelf options available

The main advantage of using the EJH-125-01-S-D-SM-LC-39 is that its design can provide a permanent connection capable of operating safely in harsh and demanding environments.

Construction

The EJH-125-01-S-D-SM-LC-39 rectangular connector is constructed from a variety of components. The body is composed of a metal shell that is able to provide robustness, as well as a stable connection. Inside the male pin, there are two contacts that are made from male-shell materials, such as silver-plated phosphor bronze and copper, which have been designed for repeated use and long-term reliability. Finally, insulation material is placed around the external contacts, which is available in an array of materials including PVC and Fluoroplastics. This insulation material can either be fabricated or preformed, with various contact-sealing options available depending on the application requirements.

Working Principle

The EJH-125-01-S-D-SM-LC-39 connector features two contacts – one inner contact and one outer contact – that are designed to conduct electricity in an accurate and efficient manner. The inner contact is able to transmit the electrical current, while the outer contact ensures that the current is isolated from the environment. When the connector is mated with its complementary female connector, the outer contacts of both components must be secured in order to ensure a low electrical resistance. In order to achieve this, they are mechanically pushed inwards, until they ‘click’ into place. The connection between male and female components is then secured with the help of locking devices, for example, tabs, screws or locks.

Conclusion

In conclusion, the EJH-125-01-S-D-SM-LC-39 rectangular connector is suitable for use in various engineering applications such as the automotive, energy and medical sectors. This connector has been designed to meet safety and environmental standards, and offers superior performance with tight, reliable connections. Constructed from high-quality materials, it has a robust metal shell and two contacts, one inner and one outer. Additionally, it is capable of providing a permanent connection thanks to its locking devices, while its insulation materials work to protect it from environmental performance.
