About the 1731121733 Molex HAND TOOL FCT MCD
The 1731121733 Molex hand tool item belongs to the FCT MCD application-tooling family and serves as the locator for size 20 crimp contacts, covering both plug and socket contacts of that size. A locator sets the contact at the correct depth and orientation within the crimp jaws, so that the wire barrel — and the insulation grip where one is present — closes on the intended part of the terminal rather than on the mating end. Changing the locator is what adapts a single hand-tool frame to a different contact size or family, which is why locators are ordered separately from the frame itself. FCT tooling is Molex’s range for machined turned contacts, which are supplied as loose pieces rather than on a reel and therefore have to be positioned individually for each crimp. Tooling of this kind is intended for prototype, low-volume and field-repair work; volume assembly is normally done on a bench press with the matching applicator.

Typical applications
This locator is kept at repair benches and in prototype build cells where size 20 turned contacts are crimped onto discrete wires before insertion into a connector housing. Typical work includes replacing damaged contacts in an existing loom, building short pre-production harnesses, and field repair of internal wiring. Because a locator only defines contact positioning, it has to be paired with the correct FCT MCD hand-tool frame and the die set appropriate to the wire gauge being terminated.
