The 1.6/5.6 series of connectors are available with three different plug designs: snap-on coupling that allows rapid but secure connections, screw coupling for vibration-proof installations, slide-on coupling which is suitable for rack and panel systems. The jack has one mating face design which will mate with all three plug types.
The maximum frequency for this series is limited to 1GHz. The impedance is controlled at 75Ohm for all types. Versions of this series connector are available for mounting to printed circuit boards using through-hole soldered techniques whilst clamp and crimp processes are used to terminate to cables. These connectors are widely used in many types of communication equipment.
