To Terminal Block or Not? That is the question

Terminal Blocks - pro's and con's 


Terminal blocks offer one method of connecting a selection of different electrical wires. They come in a range of shapes and sizes so you can normally find one that will be compatible with whatever project you are working on. However, the disadvantage of terminal blocks is that wires can come loose if knocked or due to vibration in harsh environments, even if secured well. Furthermore, time is needed to screw in each wire and maintenance which takes time.

For high power applications where safety is paramount, it is particularly important to have a highly reliable and secure connection.

The Hirose Solution - EF2 Series in-line power connectors

Hirose Electric Co. Ltd has a solution, introducing a great replacement for terminal blocks, with the EF2 Series.

The EF2 series consists of DIN rail mount type in-line power connectors that use a single action robust lock connection method for inserting standard ring terminals to maintain a stable and secure connection. 

The innovative connector design allows the crimped cable to be inserted into the connector housing in a quick and user-friendly one-step operation. The crimp contact can be easily terminated to the cable with a standard market commodity JIS C 9711 hand tool. Disconnection is made simple by pulling the contact while pushing down the button.

This series is designed to connect cables to electrical equipment such as power distribution in buildings without using screws. By eliminating screws, EF2 saves time on installation, maintenance, whilst saving time on wiring.

The series offers a wide range of cable sizes (1.25mm2 to 200mm2) and supports an extensive current range (16A to 400A).

The full EF2 series is available direct from stock from RS Components. Click here to see the full range.
