Product Number Structure
HRM--- (Series Name - Connector Type - Serial Number)
Surface Treatment Classification
- Gold-plated type
- S type (Passivated) - denoted by 'S' at the end of the part number.
Technical Guidance
- S-Type Recommendations: Passivated stainless steel offers enhanced corrosion resistance and avoids gold plating powder accumulation.
- High-Frequency Performance: Cutoff frequency calculated at 24.5 GHz; industrially usable upper limit around 18 GHz. Guaranteed frequency limit is 12.4 GHz, with some products performing up to 18 GHz typically.
- Insertion Loss: Loss 0.03 f(GHz) (dB); below 0.1 dB over the guaranteed bandwidth.
- High Frequency Leakage: More than 100 dB within the guaranteed frequency range under specified conditions.
- Coupling Tightening Torque: Recommended range is 0.6 to 1.0 Nm (6 to 10 kg/cm).
