Amphenol Commercial CTW Fan Module Connectors

Amphenol Commercial Card-to-Wire (CTW) Fan Module Connectors feature a flexible design for CTW power applications used in fan modules. The series allows different wire gauges ranging from 28AWG to 22AWG and a maximum current rating of 4A per pin. These connectors are available in standard and smart versions and offer a cost-effective solution with less airflow drop compared to conventional card-to-board fan connector solutions. The CTW standard fan module can be easily assembled with a cover, and the wires can be tidied up. Amphenol Commercial CTW Fan Module Connectors have an optional idle key for fan model identification and optional light pipe-frame orientation (left/right). The smart fan module includes an IC slot that allows the recording of fan operations through IC. The connectors have a provision of an extra pin each on the IC side and on the power side.
