SEI and SE 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 .
Suffixes are used as follows:
R denotes model less mounting positions
* The SEPX and SEFX are made with .020" standoffs for ease
in cleaning after the soldering operation
