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 Crimp Commercial Hand Tool Assembly 2432675-1 for the RITS Connector Socket Assembly is the tool

and die set shown in Figure 1. The tool consists of the SDE Crimp Frame Assembly 2362810-1 (instruction

sheet 408-35143) and the die assembly listed in Figure 1. This tool is used to crimp the connector part

numbers listed in Table 1.

drawn to scale.

Read these instructions thoroughly before crimping connectors.

2. DESCRIPTION

The tool frame features two jaws, a handle, and a ratchet adjustment wheel. The die set consists of an anvil

(upper die) and a nest (lower die). The tool frame holds a die assembly with one crimping chamber (see

Figure 1). Die-retaining pins and 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. 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. INSTALLING THE DIE SET AND LOCATOR ASSEMBLY

1. Open the tool handles.

2. Remove the two die-retaining screws from the tool jaws (see Figure 1).

3. Insert the lower nest die in the moving jaw of the tool frame with the chamfered side facing outward.

4. Insert the two long die-retaining pins.

5. Insert the long die-retaining screw through the jaw and through the nest die. Tighten the screw just

enough to hold the nest in place. Do not tighten the screw completely.

6. Insert the upper anvil die in the stationary jaw of the tool frame with the chamfered side facing outward.

7. Insert the two short die-retaining pins.

8. Insert the short die-retaining screw through the jaw and through the anvil die. Tighten the screw just

enough to hold the die in place. Do not tighten the screw completely.

9. Carefully close the tool handles, making sure the anvil and nest align properly. Continue closing the

tool handles until the ratchet in the tool frame has engaged sufficiently to hold the dies in place.

10. Tighten both die-retaining screws.

11. Place the locator assembly over the end of the long screw and position the locator against the side of

the tool jaw.

12. Place the nut onto the end of the long screw and tighten the nut enough to hold the locator in place.

4. REMOVING THE DIE SET AND LOCATOR ASSEMBLY

1. Close the tool handles until the ratchet releases.

2. Remove the nut, the locator, the two die-retaining screws, and the four die-retaining pins.

3. Slide the dies 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.

5. CRIMPING

NOTE

The tool is provided with a crimp adjustment feature. Initially, the crimp height should be verified as specified in Figure 3. Refer

to section 6, INSPECTING THE CRIMP HEIGHT, and section 7, ADJUSTING THE RATCHET, to verify crimp height before

using the tool.

1. Select a wire of the correct size and insulation diameter for the connector (see Table 1).

2. Hold the tool so that the back (wire side) is facing you (Figure 2). Squeeze the tool handles together

and allow them to open fully.

3. Insert the wires into the connector housing openings.

4. Ensure that the wires are fully seated in the connector housing.

5. Load the connector into the tool through the nest die, and into the cavity of the locator (Figure 2).

6. While holding the wires and connector in place, fully cycle the tool until the ratchet releases and allows

the handle to open.

7. Remove the crimped connector from the locator and nest die.

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 connector listed.

2. Refer to section 5, CRIMPING, and crimp the contacts accordingly.

3. Using a micrometer or caliper, measure the connector crimp height as shown in Figure 3.

If the crimp height is 0.25 mm or less, the tool is considered dimensionally correct.

If not, adjust the tool. 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.

To adjust the ratchet, complete the following steps.

1. Remove the ratchet wheel lock screw (Figure 4).

2. Rotate the adjustment wheel.

If the crimp height is larger than recommended, rotate the adjustment wheel counter-clockwise ()

to a higher setting.

If the crimp height is smaller than recommended, rotate the adjustment wheel clockwise (–) to a

lower setting.

3. Reinstall the lock screw.

4. Make a sample crimp and measure the crimp height.

5. 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 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.

Remove all lubrication and accumulated film by immersing the dies in a suitable commercial degreaser.

Store the tool in a clean, dry area.

8.2. Visual inspection

Inspect the tool and dies on a regular basis to ensure that they are not 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 tool or dies. Refer to section 9, REPLACEMENT

AND REPAIR.

9. REPLACEMENT AND REPAIR

If the dies are damaged or worn excessively, they must be replaced. Order replacement dies through your TE

representative. You can also order parts by any of the following methods:

Go to TE.com and click the Shop TE link at the top of the page.

Call 800-522-6752.
