1. INTRODUCTION

SDE-SA Hand Tool Assembly 91391-1 consists of 
SDE-SA Frame Assembly 9-1478240-0 and die set 
assembly 91391-2. See Figure 1. The tool is used to 
crimp 30-20 AWG Micro MATE-N-LOK* Pin and 
Socket Contacts.

Dimensions in this instruction sheet are in 

millimeters [with inches in brackets]. Figures and 

illustrations are for reference only and are not 

drawn to scale.

2. DESCRIPTION

The tool frame features two jaws, a handle, ratchet 
adjustment wheel, and an emergency ratchet release. 
The die set consists of an indenter (upper die) and an 
anvil (lower die). The tool frame holds a die assembly 
with two crimping chambers. See Figure 1. Die 

retaining pins and die retaining screws are used to 
position and secure the dies in the tool frame.

The tool features a ratchet and an adjustment wheel 
with a range of settings. The ratchet ensures that the 
tool has completed the cycle and will not release until 
the handles have been FULLY closed, unless the 
emergency ratchet release is rotated to manually 
release the ratchet. The adjustment wheel controls the 
amount of handle pressure exerted on the dies during 
the crimping procedure.

The dies bottom before the ratchet releases. This 

feature ensures maximum tensile performance of 

the crimp. DO NOT re-adjust the ratchet.
