The high-speed data connector system can transmit LVDS signals outstandingly. The optimized, matched impedance plug-in system can provide first-class transmission quality while preventing external interference and crosstalk. The main feature of this product is the SSR (smart stress relief) design. By fixing it with the inlet chute and the panel in the connector housing area, the stress of the solder joint can be eliminated in the circuit board connection. So as to achieve outstanding mechanical connection safety and firmness.
