Introduction

Rectangular connectors headers, male pins 178495-1, also called 180 degree headers, are used in a variety of applications, including in heavy duty automotive and industrial applications. Combining robust construction with ease of use, these connectors are ideal for use in rugged, harsh environments. In this article, we will describe the applications of 178495-1 headers, explain the working principle, and identify common features of these all-purpose male pins.

Applications of 178495-1 Headers

178495-1 headers are built for strength and are suitable for a variety of electronic connections. Common applications for these headers include:

• Industrial control systems
• Robotics and automation
• Electrical and mechanical components
• Avionics and military applications
• Commercial vehicles, construction equipment, and farming

These headers provide reliable, low-resistance connections for wiring harnesses and power distributions. Their unique design allows for both internal and external connections.

Headers Working Principle

178495-1 headers are constructed from high-performance materials, ensuring a high level of electrical and mechanical properties. The headers are designed in a solderless 180° layout, consisting of several layers of metal and insulation.The metal layers consist of a base metal, an upper metal, and a lower metal. The base metal is typically tin-plated copper alloy; the upper and lower metals are usually brass. To ensure a reliable connection, the headers feature "split-pin connectors," which separate the electrical contact point between the upper and lower metal layers. This separation prevents electrical shorts and minimizes contact resistance, giving the headers excellent resistance to heat and vibration.

Common Features

178495-1 headers feature several common features, including:

• 2.5mm mating face for secure, easy connections
• PCB mounted
• High-temperature, high-vibration connectors
• High-density design
• Low-resistance connections
• Gold-plated contacts for enhanced conductivity

They are also compatible with a variety of wiring accessories, making it easy to customize the installation.

Conclusion

178495-1 headers, male pins, are rugged, reliable connectors ideal for a variety of applications. The headers are designed with two layers of metal and insulation, which form a low-resistance connection. Additionally, the headers offer a variety of features, making them excellent choices for harsh, heavy duty applications.
