Flex connectors are available in two cable insertion configurations. The first is known as ZIF, or zero insertion force. This type of connector requires very little effort, almost zero to insert the cable into the connector. This low force results in fewer instances of cable buckling or deforming as well as provides a high number of mating cycles. Once the cable is inserted, an actuator is closed, holding the cable in place. The two main types of actuators are the traditional sliding type (also known as the garage door style) and the flip type. The sliding type provides higher retention and strain relief while the flip top offers greater ease of application, making cable insertion and actuation a one handed process.
