Suitable for 4U case

Current and voltage terminalTD4-9.4/XX-LLRR

1.Suitable for 4U case

2.The welding pin can be installed freely,which can realize the connection of the voltage loop terminal without open wire,convenient for the use of the welding voltage transformer,improve the assembly efficiency.

3.The external insulation cover plate can realize the protection grade of the product up to IP20

4.The welding pin is a separate installation type,and can be installed with the optional poles,flexible and convenient.

5.The flanges on both sides have the function of zero (ground) connection,no additional wiring is needed for PCB zero (ground) connection.

6.The outer side of the installation is equipped with a test hole for convenient testing,and test tooling can be provided.

7.Seamless replacement with current and voltage terminals,TD4 series of all 9.4mm pitch 

products.
