SC Jack (Female) 4 Hole Flange Connector 18.24mm (.718 inch), DC-11GHz

SC Jack (Female) | Solder End | 4-Hole Flange Mount | Brass Body

The ROSNOL SC2GFB50-3175A/93 is a straight panel receptacle jack designed for high-frequency RF and microwave systems. It provides a 50 Ω impedance and supports a frequency range from DC to 11 GHz, ensuring stable signal transmission. The connector features a screw-lock coupling mechanism for secure engagement and long-term reliability. Mechanical dimensions include an overall length of 31.8 mm \[1.250 in], flange diameter of 32 mm \[1.260 in], and mounting holes of Ø3.2 mm \[.126 in] arranged in a 4-hole configuration. The hole spacing between adjacent mounting holes is 18.2 mm \[.718 in], and the connector operates within a temperature range of -65°C to +165°C, meeting stringent durability requirements.

The center contact is made of beryllium copper with gold plating over a nickel underplate, delivering excellent conductivity and corrosion resistance. The body is constructed from brass with nickel plating for enhanced durability, while the insulator is PTFE, offering superior dielectric performance. Additional dimensions include a solder end diameter of Ø2.6 mm \[.103 in] and a coupling thread size of 11/16-24 UNEF-2A, ensuring compatibility with standard RF panel layouts and simplifying integration into existing systems. This robust construction guarantees mechanical strength and electrical reliability under demanding conditions.
