Terminal Blocks - Headers, Plugs and Sockets have a broad array of applications, from being used for connecting components in high-powered commercial installations, to being employed as a convenient interface for low-power hobby circuits. ELFH17150J is a representative of the range of products that make up this particular family. To better understand the various applications and working principles of ELFH17150J, let us take a closer look at its features.

Features

ELFH17150J is a 2.54mm / 0.1-inch pitch terminal block that features two rows of 1 x 7 contacts. It is designed to wire single- and dual-row pin strips and plug-in connectors. For assembly, all that is needed is manual stripping, insertion of the cable and fastening of the terminal block by saddle clamp. The product’s features make it very well suited for applications that require fast and reliable wiring solutions.

ELFH17150J is made from SGCC+PA66 and provides good fire retardance, which is a big plus for industrial applications. It also offers a rated current of 6 A, and for improved safety, it has been designed to clear V-1 Grade international insulation standards. It is hence fortified from the risk of accidental electric shocks, and heavy surge voltages.

ELFH17150J further offers two pole setting positions in and against the direction of insertion, which allows for space-saving and easier mounting. To add to its versatility, the product can also withstand vibration and is equipped with a self-clean contact system, which allows for reliable current transfer even in presence of dust, dirt, grease, or water spray.

Applications

ELFH17150J is extensively used in industrial automation, automotive, railway, instrument, robot, renewable energy, and many other markets. Its flame-retardant characteristics make it a good fit for hazardous and combustible processes that demand safe and reliable wiring. With its wire insertion and automatic tight wire clamp design, it is also well suited for applications such as moving and vibrating machines and outdoor appliances.

In terms of electronic applications, ELFH17150J can be found connecting boards of various types, including processor boards, communication boards, RF boards, and other single- and double-row boards. It also finds use in connecting relays, contactors, and other equipment. For instance, it can be found providing automatic terminal connection for thermocouples and RTDs.

Working Principles

In physical terms, ELFH17150J combines multiple parts such as insulation housing, spring clamp, handle, support stem, and self-cleaning contacts. The spring clamp provides necessary holding force which is supplemented by the insulation housing, the handle upon chamber locking carries its own set of locking force. This combined force helps ensure an excellent connection between cable and contact area.

From an electrical standpoint, ELFH17150J uses nickel plating on its contact points to help enhance the current flow between cable and contact. With a rated current of 6 A, the contact pressure generated by default also provides the requisite insulation resistance to ensure a safe and reliable connection. Since, the product is designed to achieve international V-1 Grade insulation performance, it offers stronger electrical current carrying capability and better surge protection.

ELFH17150J further utilizes a self-cleaning mechanism, which allows the contact points to be dust and dirt resistant. This ensures that the connection between cable and contact area is maintained, and a continuity of current flow is maintained even in presence of dust and debris.

Conclusion

This concludes the overview of the various applications and working principles related to ELFH17150J terminal blocks, headers, plugs and sockets. It is an ideal product for industrial applications that require safe and reliable wiring solutions. With its good fire retardance and self-clean contact system, ELFH17150J can protect against accidental electric shocks, as well as provide continuity of current even in presence of dust and dirt.
