Positive locking connectors for safe reliable connections


Molex’s FiT families feature positive locking latches designed with an audible click to give operators feedback that the parts have been securely mated. In addition, positive locking also prevents accidental unmating from shock, vibration or moderate strain being placed on the cable. By audibly signaling a positive lock, FiT families connectors indicate that they are fully mated and ultimately prevent assembly errors. This improves quality during final product assembly by ensuring consistent operation over the life of the product.


Within the FiT families, Ultra-Fit™ and Nano-Fit™ connectors offer inner-locking latches that are more resistant to accidental unmating. If the latch is snagged by a wire, glove, or other object, it will only hold the latch in the locked position instead of potentially deactivating it. By audibly signaling a positive lock, FiT connectors indicate that they are fully mated, ultimately preventing assembly errors.

Scoop proof design protects contacts from being damaged during mating/unmating


Molex’s FiT families feature scoop proof contacts designed to protect critical contacts from damage associated with mating and unmating. With a scoop proof design, contacts are protect- ed until the mating connectors are properly aligned. Therefore, damages related to aggressive unaligned mating and unmating are virtually eliminated.

Fully isolated contacts inhibit arcing and allow for higher voltage ratings


Molex’s FiT families feature fully isolated contacts that inhibit arcing between contacts and provide the use of higher volt- ages as well as better electrical isolation between adjacent contacts. As a result of isolating the contacts, damage can be prevented during handling, and shorting risks due to debris are minimised.
