Hand tools are intended for occasional use and low volume applications. A wide selection of powered application equipment for extended use production operations may be available. into the contact. The ratchet assures full crimping of the contact. Once engaged, the ratchet will not release until the dies have been fully closed. 3. CRIMPING PROCEDURE Do NOT cut or nick the wire strands during wire stripping. 1. Select the desired terminal listed in the Figure 3. 2. Make sure the center of the locator is in the down posi- tion. With the locator attached, push the locator button on the back of the hand tool to bring the locator forward through the tooling. 3. While holding the locator button in, load the terminal into the proper nest opening in the locator based on the wire gauge or terminal type markings on the hand tooling. 4. Release the locator button, allowing the locator to return Figure 1 to the crimping position. 1. INTRODUCTION 5.

DESCRIPTION The front of the tool is marked with the tool part number. The tool features a fixed die (crimper), a movable die Figure 2 (anvil), a locator, and a ratchet. The locator positions the contact and limits the insertion distance of the stripped wire CUSTOMER SERVICE +1-800-726-8329 (+1-812-944-6733) 1 of 3Straight Action Hand Tool CAT-HT-174-2030-13 STS-M-174-2030-13 Contact Wire Size Insulation Strip Crimp 2 Number mm AWG Diameter Length Height 0.05 30 0.74 .029 - 0.89 .035 0.08 28 0.81 .032 - 0.97 .038 See Application See Application Tooling Tooling 0.12 26 1.22 .048 - 1.37 .054 T1M74 Section of Section of 0.20 24 1.35 .053 - 1.50 .059 Samtec Samtec 0.35 22 1.50 .059 - 1.65 .065 Website Website 0.50 20 1.68 .066 - 1.83 .072 Figure 3 7.

When tool is not in use, keep the handles closed to pre- vent objects from becoming lodged in the crimping dies, and store the tool in a clean, dry area. 4. MAINTENANCE AND INSPECTION PROCEDURE It is recommended that a maintenance and inspection pro- gram be performed periodically to ensure dependable and uniform terminations. Frequency of inspection depends on: The care, amount of use, and handling of the hand tool, The presence of abnormal amounts of dust and dirt, Your own established standards.
