Product Description
3.5mm Male 2-Hole Flange Mount Field-Replaceable RF Connector – Model 3.5-JFD31
The 3.5 mm male 2-hole flange mount RF connector with a 0.23 mm pin and 12.7 mm hole spacing is engineered for high-precision RF test setups and broadband measurement systems. The field-replaceable construction enables rapid maintenance and repeatable calibration without soldering, ensuring consistent electrical integrity.
Electrical Accuracy and Frequency Range
With 50 Ω impedance, VSWR ≤ 1.1, and insertion loss ≤ 0.06 √F(GHz) dB, the 3.5-JFD31 connector ensures low return loss and accurate signal transmission up to 26.5 GHz. Ideal for broadband analyzers and calibration devices. See other precision interfaces in our 3.5 mm connector lineup.
Material Strength and Certification Compliance
Manufactured from corrosion-resistant stainless steel and fitted with gold-plated beryllium copper contacts, this connector delivers both long mechanical life and low contact resistance. Each piece is fully REACH and RoHS compliant. Find similar configurations under flange-mount connectors.
Mounting Geometry and Structural Design
The 2-hole flange mount layout with 12.7 mm spacing provides a rigid and vibration-resistant attachment ideal for RF panels and modular instruments. Its geometry ensures mechanical alignment and repeatability. Visit our RF connector catalog for more precision options.
Corresponding Female Model
Use alongside the 3.5 mm female 2-hole flange mount RF connector – Model 3.5-KFD31 to achieve optimized return-loss balance and consistent broadband calibration performance.
