Terminal blocks are the mainstay of industrial automation in many applications. Wire-to-board solutions, such as 1891360 terminal blocks, are designed to streamline wiring tasks and reduce the amount of time and resources spent on harnessing connections. In this article, we’ll discuss the 1891360 application field and working principle in detail.

Clearance and Creepage Requirements

Terminal blocks are designed for use among a variety of electrical equipment. As such, providing a safe connection in line with safety standards is essential. Clearance (um) and creepage (mm) both refer to the physical space between two points on the terminal block. Clearance is measured in micro-meters (um) and depicts the distance between two pins on the Same Side of the terminal block. Creepage is measured in millimeters (mm) and encompasses the distance between two pins on Opposite Sides of the terminal block.

For the 1891360 terminal block, the clearance and creepage requirements are 55um/4.5mm. This ensures that any potential emitted energy traveling between nodes can be adequately dispersed, protecting users from electrical arcing.

Safety Compliant

The 1891360 range of terminal blocks are UL rated for safety standards compliance. All terminal blocks come with clear labeling, providing users with comprehensive information regarding wiring instructions, ratings, and other critical information. Additionally, the 1891360 terminal blocks feature an integrated test point, with a standard resistance of 0.25 Ohm. A reliable connection can easily be ascertained by measuring resistance values at the test point.

Common insulation applications

Insulation on the 1891360 terminal blocks comes in a variety of materials, including electro-ceramic, phenolic, and Polyamide. It is important to remember that these materials are custom designed for specific applications. Electro-ceramic insulation offers excellent protection against electrical arcing, making it ideal for high powered applications and other applications in hazardous environments.Meanwhile, the phenolic insulation is lightweight and best suited for low power applications and relatively low voltage, while Polyamide is perfect for high-density applications.

Durability and Reliability

The 1891360 terminal blocks are extremely durable and reliable. They feature a robust body and solid construction, enabling them to withstand normal wear and tear. Their robust design also enables them to remain in place within the power application area, making them ideal for stationary equipment. To ensure maximum longevity and reliability, individual components of the terminal blocks have been gold-plated, providing superior corrosion resistance.

Working Principle

The 1891360 terminal block utilizes an input wire-to-output wire terminal block connection system, enabling wires to be connected from one board to another. The terminals feature a secure, push-in connection, eliminating the need for additional fasteners or hardware.The terminal block\'s distinguishing feature is its advanced contact system, which is designed to provide superior electrical connection and ensure maximum current-carrying capacity and low contact resistance. This contact system allows for a large degree of flexibility, enabling wires of all sizes and shapes to be connected.

Conclusion

The 1891360 range of terminal blocks is ideal for industrial automation applications, offering users a reliable, secure connection. The terminal blocks come with a number of features, including clearance and creepage requirements, UL rated safety, insulation materials, and gold-plating. All these features come together to provide superior durability and reliability, ensuring maximum performance and longevity. With all these features, the 1891360 range of terminal blocks is the perfect choice for wire-to-board applications.
