Introduction

Rectangular Connectors - Headers, Male Pins, are abutting contact connectors used for electronic boards and cables. They have two basic types: Wire-to-Board and Cable-to-Board. The 151248-7422-RB is a representative variant in this segment of the electronic product family and is often referred in the industrial community as a Male Pin Header. The purpose of this article is to give a detailed description regarding the application field and working principles of this particular variant of male pin header.

Mechanical Components

151248-7422-RB is a low profile male pin header connector that can accommodate a range of standard AWG (American Wire Gauge) wires or cables. It consists of 4 straight-through pins arranged in two sets of two pins, each with a single entry, and in a row-by-row configuration. It features an insulated Phosphor Bronze housing, with a Nickel-plated finish over an insulated Polycap. The interconnecting parts are made of RoHS material and are perfect for high temperature applications. The male pins feature an insulated back shell, brass shank, solder tail, and nitrile insulator.

Specification

The 151248-7422-RB Male Pin Header Connector is a compact but a reliable option for wire-to-board connections. Its nominal voltage is rated at 250VAC, with a current rating of 10A. It is available in straight as well as right angle configurations, with a pitch size of 0.1" (2.54 mm). The body is 0.25" (6.3mm) wide, with an overall height of 0.355" (9mm). It weighs approximately 1.2 ounces (0.05 kg).

Environmental Aspects

151248-7422-RB Pin Header Connector can withstand temperatures ranging from -55° C to +105° C and operating temperature up to +85° C. It is also RoHS Compliant and UL 94V-0 approved. This connector is also rated IP67, indicating its protective capability against dust, solvents, and water.

Applications and Working Principles

The 151248-7422-RB Male Pin Header Connector is a standard option suitable for many types of electrical and communication connections, both in industrial as well as commercial applications. Its low profile feature makes it suitable for installation in tight areas. Moreover, its reliability and good resistance to temperature variations make it an ideal connector for demanding applications. The working principle of this connector is based on abutting contact. It primarily uses a crimp connection system, where the wires or cables to be connected are crimped over the pins to form a secure connection. The electrical connection is further enhanced through a soldered connection. The solder tail aids in preventing oxidation of the pins, thus increasing its life.

Conclusion

The 151248-7422-RB Male Pin Header Connector is a reliable and economical solution for a wide variety of industrial and commercial applications. It features an insulated Phosphor Bronze housing and Nickel-plated finish over an insulated Polycap, making it suitable for temperature extremes. It is a compact and low profile connector, thus suitable for installation in tight spaces. Its abutting contact and crimp connection system further improve its electrical characteristics and offer increased reliability in different scenarios.
