Precision Test Connectors


Molex’s Precision Connectors are designed for equipment where reliable high-frequency performance is critical


Molex's Precision Test ConnectorsMolex's precision test connectors offer high frequency performance response for the most demanding high frequency applications. Optimized SMAs achieve maximum frequency response of 27 GHz while the 2.4 mm connectors achieve a maximum frequency response of 50 GHz.

Through the utilization of a unique construction, Molex Precision test connectors do not require soldering to the PCB; rather the connectors are tightened to the PCB using 0-80 UNF screws. The center contact inside of the connector makes first contact to the PCB and moves into optimal pin position inside of the connector as it is tightened to the PCB. A 360° grounding ring ensures optimal shielding. PCB traces transition from the connector to the PCB using a plated through hole via on the PCB to transfer to a trace in lower layers of the PCB.
