A-TB254-HA18H

A-TB254-HA18H is an existing type of terminal block which belongs to the Wire to Board category. This terminal block series was designed to provide solutions for applications in a variety of industries and meets a wide range of application demands. It was developed by linking multiple points of contacts between the wire and the printed circuit board (PCB) and can be very easily mounted onto the PCB.

The A-TB254-HA18H is a two-position (2P) terminal block with 14 AWG-24 AWG size options. It is composed of a flat body part, a plastic spring-toe piece, metal contact spring for earth connection, an M4 oblate head screw, and a wire entrance hole. It is designed for high-temperature applications with its working temperature range extended from -40℃ to 125℃ (with short excursion up to 135℃). Because it is a type of ultra-small terminal block, the overall length of the A-TB254-HA18H is only 24.5mm and this makes it an ideal option for various applications.

Generally, A-TB254-HA18H is broadly applied in domestic appliances such as refrigerators and washing machines, and in commercial and industrial applications. In addition, it is also suitable for PCB, display signal, power supply, board-to-board, and digital communication system interface connection.

In terms of electrical performance, A-TB254-HA18H typically provides 500VAC (alternating current) /1000VDC (direct current) rated insulation voltage, rated current range from 5A-20A, and rated power stability range from 73.5VA-148W. This terminal-block series has a reliable copper (C4500-C5000) claw grip conductor that offers secure contact connection with conductors.

Regarding UL approval, A-TB254-HA18H was tested and verified according to IEC/EN61984, UL1059 and CSA C22.2 regulations. Its complete material set and cosmetic appeal meet various standards, such as UL, CSA and VDE. On the other hand, A-TB254-HA18H ensures good plug/unplug force which would give a good mating foundation and ensure excellent electrical performance.

The working process of A-TB254-HA18H is straightforward. To start with, one would need to loosen the screw before inserting the wiring. Then the wire can be inserted into the PVC housing of the terminal and pressed down onto the screw head using a suitable tool. Lastly, once it is tightened, the screw and clamping plate will secure the inserted wire.

In conclusion, A-TB254-HA18H terminal block is an important part of the Wire to Board terminal block series. It is well-suited for applications in the field of household electrical appliances, digital communication systems, display signals, and board-to-board connections. Furthermore, its electrical and mechanical performance is reliable and surpasses a lot of international standards - thus, making it a dependable electrical connection solution.
