Hokuyo MBX-301CA Microwave type Close crane warning device Microwave type not affected by vapor, disturbance light or smoke This is a microwave detector. It consists of an antenna as detecting part and control unit composed of oscillator, wave detector and amplifier, and these two components are coupled together by a wave guide. Since the antenna is free from any electronic part which may be affected by heat, it can be used in high temperature environment without being cooled by water. This device is suitable for using under bad environment because microwave isn’t affected by vapor, disturbance light,smoke etc. This device is reflective type. It is possible to detect small pipe, too. This device provides monitor output that is monitoring oscillation of microwave. ,1,85,1,hokuyo-MBX-301CA-waveguide-type-sensor,,2015-10-26 11:11:00,,9886,0,,0,İmaj Teknik MBX-301CA – Waveguide type sensor Hokuyo Sensors for Special Applications/Iron and Steel Industry,, Specifications Model No. Control unit: MBX-301CA Antenna: MAR-201(Without air-purge), MAR-251(With air-purge) Waveguide: MWG-20(Semi-seamless 2m), MWG-25(Seamless 2m), MFG-20(Flexible 0.5m) Joint: MSJ-20(Socket), MBJ-25(Elbow), MCJ-20(Elbow with 45°) Detectable objects Steel plate with reflection surface, 50×50mm or more Detecting distance Approx. 300mm from antenna surface Hysteresis 1mm to 30mm(Adjustable) Microwave 10.525GHz ±15MHz Allowable waveguide length 25m or less(Total of transmission and reception) Air blowing of waveguide Air quality : Industrial clean air, Air amount : 20 lit/min., Air pressure : 980KPa(In case of MAR-251) Power source 100 to 110VAC/200 to 220VAC(±10%, 50/60Hz) Power consumption 4.5VA or less Control output Contact : 1C relay contact(250VAC 3A, 30VDC 5A, cosφ=1) Photo-coupler(75V 100mA) Alarm output *1 1C relay Contact(250VAC 3A, 30VDC 5A, cosφ=1) Response time Contact output : 10msec, photo-coupler output : 3msec Connection M4 screw terminal, hub body with gland(Hole diameterφ18) Display lamp Power lamp, operation lamp, alarm lamp, 5-step reception level lamp *2 Ambient temperature Control unit : -10 to +60°, Antenna/waveguide : -20 to +600° Case Antenna : Bronze casting, Control unit : Aluminum die-casting Weight Control unit : approx. 10kg, Antenna : approx. 11kg *1 When oscillation of microwave is stopped by power failure or circuit trouble, this output is executed. *2 Reception level is indicated with 5 steps.
