NON-ZIF type/NON-ZIF connector (Non-Zero Insertion Force)

It is not a ZIF connector, that is, a connector that requires force (insertion force) when Mating the card into the connector. Focusing on those with relatively low insertion force, it also includes what is called LIF (Low Insertion Force).

This type does not have a locking mechanism like the ZIF connector, but instead the terminals are arranged to have contact pressure from the beginning, which is a simple connector that also serves as a card holder. Therefore, it is superior in terms of workability and size, and it is easy to keep costs down.

On the other hand, there are disadvantages such as a weaker retention force especially when there are few poles (a small Pin Counts), and conversely, a higher insertion force is required when increasing the number of poles, which can be straining.
