How to Order
E Series terminal blocks are ordered by listing a composite number made up of the model designation followed by the number of poles required for the application. Example: A Type E 10-pole block becomes stock number E-10.

Suffixes are used as follows:
R X	Denotes model less mounting positions Denotes model with thermoplastic molding

The E-10 described above less mounting positions thus converts to stock number ER-10.

*The EPX and EFTX are made with .020" standoffs for ease in cleaning after the soldering operation.
