Series SE-SEI
Features

Miniature Feed-Thru Printed Circuit and Surface Connection - SE Series miniature terminal blocks are designed for applications requiring the compactness and versatility of the SEI Series without full feed-thru insulation

Barrier-Type Construction - Blocks are made of high-impact, break-resistant thermoplastic molding with integrally mounted .116 inch diameter mounting holes. One thru 26 terminals on 1/4" center-to-center spacing.

Terminal Flexability - External terminals available in two No. 2-56 screw designs. Internal terminals include an .047" diameter printed circuit pin, and turret-type solder pins.

Wire Sizes - No. 2-56 screws. UL recognized for No. 22 AWG to No. 16AWG

Recognition and Listings - UL Recognized

Standoffs - SEPX and SEFX are now supplied with .020" standoffs for ease in cleaning after soldering

  Recogniized under the Components Program of Underwriters Laboratories, Inc. Standard 1059, Guide No.XCFR2, File No.E62557.
Guide No.184-N-90, Report No.LR39186-1.

How to Order
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.
