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

MATE-AX Hand Tool Assemblies are the tools shown in Figure 1. Each tool consists of the SDE-SA Frame

Assembly 9-1478240-0 (instruction sheet 408-8851) and a die assembly. These tools are used to crimp the

terminal part numbers listed in Table 1.

NOTE

Dimensions in this instruction sheet are in millimeters with [inches in brackets]. Figures are for reference only and are not

drawn to scale.

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 (Figure 2). 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 6, ADJUSTING THE RATCHET).

3. INSTALLING AND REMOVING THE DIE SET AND LOCATOR ASSEMBLY

1. Open the tool handles and remove the two die retaining screws from the tool jaws.

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

4.1. Inner ferrule tools

NOTE

The tool is provided with a crimp adjustment feature. Initially, the crimp height should be verified as specified in Figure 9. Refer

to Section 5, INSPECTING THE CRIMP HEIGHT, and Section 6, ADJUSTING THE RATCHET, to verify crimp height before

using the tool to crimp contacts and wire sizes.

1. Refer to Table 1 and select the cable of the specified size for the application.

2. Strip the cable jacket to the specified length in TE Specification 114-94413. Do not nick or cut

braid strands.

3. Select the applicable contact and identify the appropriate crimp tool according to the cable type.

4. Hold the tool so that the back (wire side) is facing you. Squeeze the tool handles together and

allow them to open fully.

5. Insert a section of strip product in the floating shear and advance to center the ferrule over the

anvil. The floating shear has a ball detent to assist positioning the ferrule (Figure 3).

6. Position the stripped cable (see TE Specification 114-94413 Section 5.1 Step 1 for cable

preparation) in the floating shear and seat the face of the stripped jacket against the locating

surface in the floating shear (Figure 4).

7. While holding the cable in place, fully cycle the tool until the ratchet releases and allows the

handles to fully open.

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.

8. Remove the crimper ferrule and inspect according to TE Specification 114-94413 Section 4.1.2 for

crimp height and position. See also Table 2.

3. Position the prepared cable (see TE Specification 114-94413 Section 5.3 Step 3 for cable preparation)

with the crimped ferrule in the floating shear placing the gap of the ferrule to the outer insulation in the

locating feature of the floating shear. Align the seam in the ferrule with the mark on the floating shear

as shown in Figure 6.

5. 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, and crimp the contacts accordingly.

3. Using a crimp height comparator, measure the wire barrel crimp height listed in Table 2, Table 3, or

Table 4.

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 6, ADJUSTING THE RATCHET.

CAUTION

Do not use damaged product. If a damaged contact is evident, replace it. Do not re-terminate contacts.

6. 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 10 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, replace the tool or

die set. See Section 8, REPLACEMENT AND REPAIR.

7. MAINTENANCE AND INSPECTION

7.1. 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.

7.2. 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, replace the dies. Refer to Section 8, REPLACEMENT AND

REPAIR.
