Quadrax Contacts
Amphenol Quadrax contacts offer several advantages for high data transfer rates, low power consumption, and excellent EMI compatibility.
Quadrax contacts have four strategically spaced inner contacts that form two 100Ω or 150Ω matched impedance differential pairs.
Quadrax is available in a size 8 crimp & pcb termination styles
