EHT-122-01-S-D-SM-03-K rectangular connectors, otherwise known as headers with male pins, are used commonly in a variety of applications across many different electronic devices. A few of their most popular uses include in circuit board interconnection, wire-to-board and wire-to-wire connections.
The typical configuration for headers is a right angle design, limiting the height of the assembly and allowing for a straight thru connection between two boards. They are usually found in two to twelve pin varieties with some having up to twenty-four pins.
The majority of rectangular connectors, specifically the EHT-122-01-S-D-SM-03-K, are designed to provide electrical interconnections to assemble circuit boards together. The advantages they offer are low cost, a fast means of connection and high electrical integrity.
In the EHT-122-01-S-D-SM-03-K rectangular connectors, the male pin is an electrical conductor that fits within an insulating material (often plastic) to form part of the electrical contact. The contact pins supplied by the manufacturer are usually tipped with a gold plating which ensures good signal integrity.
The design of the EHT-122-01-S-D-SM-03-K connectors significantly reduces potential interference, making them suitable for precision-based digital and analog applications. The use of these rectangular headers allows users to easily assembles board to board or wire to board connections, saving time and cost on the assembly process.
The working principle of the EHT-122-01-S-D-SM-03-K rectangular connectors is essentially similar to conventional plug and socket connections, but with a few additions. Firstly, the header contacts are opposed and offset from the socket contacts. This means that the electrical signal must travel through the male pins of the header and then be re-routed through the socket contacts to be connected to the circuit board. This process significantly reduces the potential for signal degradation between boards.
Secondly, headers may require soldering. As header pins are opposed and offset from the circuit boards, solder is needed to bridge the two components. However, depending on the type of connection, other means of assembly can be used, such as crimping, IDC or screw machining.
In conclusion, EHT-122-01-S-D-SM-03-K rectangular connectors are used commonly in a variety of applications as a reliable and efficient means of connecting two or more boards together. Their fast assembly and reduced signal degradation make them a popular choice for digital and analog applications.
