BK Mikro7 Compact System for Tool, Object and Free Space Monitoring

BK Mikro7 is based on existing design concepts for tool, object and free space monitoring and can be used universally for different types of monitoring by the integration of multifarious functions:


  • Very compact scanner design
  • Scanning in one direction or in both directions
  • Two steps for scanning intensity
  • Two ranges of tolerance for "O.K." message
  • Indication of the scanning result by two LEDs "O.K." and "K.O." on the control unit
  • Detection of cable breaks
  • Air barrier adapter as option to use the tool monitoring system system in surroundings with aggressive coolants
