PROPER USE GUIDELINES
Cumulative Trauma Disorders can result from the prolonged use of manually powered hand tools. Hand tools are intended for occasional
use and low-volume applications. A wide selection of powered application equipment is available for extended-use production operations.
The SDE-SA hand tool is a commercial-grade tool. Product crimped with this tool meets the wire barrel crimp height requirement for hand
tools in the appropriate 114 application specification, but might not comply with other feature parameters of the specification.

1. INTRODUCTION
SDE-SA Commercial Hand Tool Assembly 2391435-1 for the size 20 S&F pin and socket contacts is the tool
and die set shown in Figure 1. The tool consists of the SDE-SA Frame Assembly 9-1478240-0 (instruction
sheet 408-8851) and the die assembly listed in Figure 1. This tool is used to crimp the terminal part numbers
listed in Table 1.

Read these instructions thoroughly before crimping connectors.
2. DESCRIPTION
The tool frame features two jaws, a handle, a ratchet adjustment wheel, and an emergency ratchet release.
The die set consists of a crimper (upper die) and an anvil (lower die). The tool frame holds a die assembly with
one or more crimping chambers (see Figure 1). Die retaining pins and die retaining screws are used to 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 does 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.
CAUTION
The dies bottom before the ratchet releases. This feature ensures maximum tensile performance of the crimp. Do not re-
adjust the ratchet unless you have verified that the crimp height is incorrect (see section 7, ADJUSTING THE RATCHET).

3. INSTALLATION AND REMOVAL OF DIE SET AND LOCATOR ASSEMBLY
1. Open the tool handles and remove the two die retaining screws from the tool jaws (see Figure 1).
2. Place the wire anvil and insulation anvil so that their chamfered sides and the marked surfaces face
outward when mounted in the moving jaw of the tool frame.
3. Insert the two die retaining pins.
4. Insert the short die retaining screw through the jaw and through the anvil dies. Tighten the screw just
enough to hold the die in place. Do not tighten the screw completely.
5. Place the wire crimper and insulation crimper so that the chamfered sides and the marked surface face
outward when mounted in the stationary jaw of the tool frame.
6. Insert the two die retaining pins.
7. Insert the long die retaining screw through the jaw and through the crimper dies. Tighten the screw just
enough to hold the die in place. Do not tighten the screw completely.
8. Carefully close the tool handles, making sure the anvil and crimper align properly. Continue closing the
tool handles until the ratchet in the tool frame has engaged sufficiently to hold the anvil and crimper in
place. Tighten both die retaining screws.
9. Place the locator assembly over the end of the long screw and position the locator assembly against
the side of the tool jaw.
10. Place the nut onto the end of the long screw and tighten the nut enough to hold the locator assembly in
place, while still allowing the locator blade to slide up and down.
11. To disassemble, close the tool handles until the ratchet releases. Remove the nut, the locator
assembly, the two die retaining screws, and the four die retaining pins. Slide the anvil and crimper out
of the tool jaws.
NOTE
The ratchet release has detents with audible clicks as the handles are closed. The ratchet releases on the sixth click.

4. CRIMPING PROCEDURE
NOTE
The tool is provided with a crimp adjustment feature. Initially, the crimp height should be verified as specified in Figure 4. Refer
to Section 6, INSPECTING THE CRIMP HEIGHT, and Section 7, ADJUSTING THE RATCHET, to verify crimp height before
using the tool to crimp contacts and wire sizes.
Refer to Table 1 and select wire of the specified size and insulation diameter. Strip the wire to the length
indicated. Do not nick or cut wire strands. Select an applicable contact and identify the appropriate crimp
section according to the wire size markings on the tool. Refer to Figure 2 and proceed as follows:
1. Hold the tool so that the back (wire side) is facing you. Squeeze the tool handles together and allow
them to open fully.
2. Holding the contact by the mating end, insert the contact through the front of the tool and into the
appropriate crimp section.
3. Position the contact so that the U of the wire barrel faces the top of the tool. Place the contact up into
the nest so that the wire barrel is against the spring-loaded locator.
CAUTION
Make sure that both sides of the wire barrel are started evenly into the crimping section. Do not attempt to crimp an
improperly positioned contact.
4. Close the handles of the tool until the contact is lightly held by the die set, but is not deformed to the
point where the wire cannot enter freely.
5. Insert the wire into the crimp barrel of the contact until it butts against the spring-loaded locator.
6. While holding the wire in place, fully cycle the tool until the ratchet releases and allows the handle to
open.

5. ADJUSTING THE CONTACT SUPPORT
The contact support is preset prior to shipment, but minor adjustments may be necessary. Refer to Figure 3
and proceed as follows:
1. Make a sample crimp and determine if the contact is straight, bending upward, or bending downward.
2. If adjustment is required, loosen the screw that holds the contact support onto the locator assembly.
3. Place a contact with wire into the proper nest and close the handles until the ratchet reaches the sixth
click, or until the contact support touches the contact.
4. Move the contact support as required to eliminate the bending of the contact.
5. Tighten the screw and close the handles until the ratchet releases.
6. Remove and inspect the contact.
7. Make another sample crimp. If the contact is still being bent during crimping, repeat the adjustment
procedure.

6. INSPECTING THE CRIMP HEIGHT
Crimp height inspection is performed using a micrometer with a modified anvil, commonly referred to as a
crimp-height comparator. TE Connectivity does not manufacture or market crimp height comparators. Detailed
information on obtaining and using crimp-height comparators can be found in Instruction Sheet 408-7424.
1. Refer to Table 1 and select a wire (maximum size) for each crimp section listed.
2. Refer to Section 4, CRIMPING PROCEDURE, and crimp the contacts accordingly.
3. Using a crimp height comparator, measure the wire barrel crimp height listed in Table 2. If the crimp
height conforms to that shown in the table, the tool is considered dimensionally correct. If not, the tool
must be adjusted. Refer to Section 7, ADJUSTING THE RATCHET.
CAUTION
Do not use damaged product. If a damaged contact is evident, replace it. Do not re-terminate contacts.

7. ADJUSTING THE RATCHET
The ratchet is preset prior to shipment, but it is important to verify the crimp height using a micrometer or
caliper. Use and wear can cause the tool to go out of adjustment. Inspect the crimp height and adjust the
ratchet, if necessary, on a regular basis. Refer to Figure 5 and proceed as follows:
If the crimp height is larger than recommended, remove the ratchet wheel adjustment screw and rotate
the adjustment wheel counterclockwise (+) to a higher setting. Reinstall the screw. Repeat as required.
If the crimp height is smaller than recommended, remove the ratchet wheel adjustment screw and
rotate the adjustment wheel clockwise (-) to a lower setting. Reinstall the screw. Repeat as required.
If the crimp height cannot be made to conform to the recommended crimp height, the tool or die set
must be replaced. See Section 9, REPLACEMENT AND REPAIR.

8. MAINTENANCE AND INSPECTION
8.1. Maintenance
Remove dust, moisture, and other contaminants with a clean soft brush or soft lint-free cloth. Do not
use objects that could damage the dies or tool.
When the tool is not in use, keep the handles closed to prevent objects from becoming lodged in the
dies. Store the tool in a clean, dry area.
Remove all lubrication and accumulated film by immersing the dies in a suitable commercial degreaser.
8.2. Visual inspection
Inspect the tool and dies on a regular basis to ensure that they have not become worn or damaged.
Make sure that the die retaining screws are properly secured.
Inspect the crimping chambers of the die assembly for flattened, chipped, worn, or broken areas. If
damage or abnormal wear is evident, the dies must be replaced. Refer to Section 9, REPLACEMENT
AND REPAIR.
