The T5747 is a positioner used to ensure the correct placement of female signal barrel crimp contacts within a crimping tool. It is specifically designed to be used with an applicable hand crimp tool, such as the M22520/2-01, which is a precision tool with a ratchet mechanism and an 8-indent form. The positioner holds the contact securely in the proper orientation to achieve a reliable and consistent crimp. This makes it an essential component for assembling Datamate connectors, ensuring high-quality terminations for signal contacts.
