Introduction

The SCXI-1381K is intended for developers of custom SCXI terminal
blocks who design and lay out custom circuit boards for terminal blocks.
The SCXI-1381K terminal block housing kit includes the unassembled
components you need to build a custom SCXI terminal block. Your kit
contains all the following mechanical components of an SCXI terminal
block:

The metal enclosure

Front and back panels

Connectors, not including the circuit board

A 96-position, right-angle DIN connector for attaching to your custom
circuit board, if needed

What You Need to Get Started

To use your SCXI-1381K to build a custom SCXI terminal block, you need
the following:

SCXI-1381K terminal block housing kit, containing the following:
