Compact Bayonet Lock Coaxial Connector BM1 Series Characteristic Impedance 50 Ω Frequency Range DC to 6GHz Lock Type Bayonet FEATURE ・ Downsize a BNC connector and it is the size equal to SMA connectors. ・Apploximately 50% of space-saving in comparison with BNC connector. ・Locking type is Bayonet locking like BNC connector. ・ Because of Bayonet locking, torque management is not necessary and easier mating/unmating than SMA connector. APPLICATIONS ・Wiress Base Station, Telecom Equipment, Measuring Equipment SPECIFICATIONS Characteristic Impedance Rated Voltage Dielectric Withstand Voltage Insulation Resistance Contact Resistance V.S.W.R.
