Introduction

Terminal blocks, also known as terminal strips, are an essential component of every electrical system. They provide a secure connection between electrical components, shielding them from each other and reducing contact resistance. They are typically used to connect switches, relays, fuses, sensors, and other electrical devices. The TJ1871800000G is a terminal block designed for industrial, commercial, and residential applications. It is rated for a maximum current of 8A/250VAC, and its durable construction ensures reliable connections. To better understand its application field and working principle, let us look at the block\'s features and specifications.

Features and Specifications

The TJ1871800000G terminal block is a single-row, eight-way terminal block with a 0.2 mm pin spacing. It is designed for use with either stranded or solid core wire in sizes ranging from 12-26 AWG (cross section area: 0.5-0.75mm2). The block is made out of a durable plastic thermoplastic material that ensures excellent electrical insulation and mechanical resistance.The block is equipped with a recessed mounting hole at the end of each pin, allowing for firm and secure mounting of the block to the desired surface. The TJ1871800000G also has a universal polarization feature, meaning that each of the pins can be connected to either the positive or negative terminal.

Application Field and Working Principle

The TJ1871800000G is designed for a wide range of applications, from traditional machine control, factory automation, signal and power distribution, to commercial and residential applications. It can be used to connect switches, relays, fuses, sensors, and other electrical devices. The block is especially useful in environments where space is limited, as its compact design enables tight wire routing and installation.The terminal block\'s working principle is relatively simple. It works by providing a secure connection between the two wires, using the spring-loaded contact pins that are housed within the block. When the terminal block is connected to the wires, the contact pins press against the wire\'s insulation and create a secure electrical connection. This secure connection ensures that no current is lost in the connection, thus minimizing contact resistance and increasing the terminal block\'s electrical efficiency.The TJ1871800000G terminal block is also equipped with a special “self-wiping” feature. This feature works by cleaning the wire\'s insulation with each new connection, thus providing longer-lasting connections and reducing contact resistance. Thanks to this self-cleaning feature, the block is also suitable for use in dusty and harsh environments.

Conclusion

The TJ1871800000G terminal block is a great choice for numerous applications that require a secure and reliable connection. Its durable construction ensures a reliable connection, and its special “self-wiping” feature helps to keep contact resistance low and improve the block\'s electrical efficiency. The block is suitable for use in both commercial and residential environments, as well as in traditional machine control and factory automation.
