+Ordering notes

  • Index EKP: With control valves
  • Index EKPP: Without control valves
  • The performance data are identical for the two series
  • The optional check valve maintains the vacuum in cases of compressed air failure for a certain period of time to prevent sudden dropping of the workpiece
  • On request, ejectors are also available normally (current free) open (NO):
    In case of power failure, compressed air line remains open and workpiece is held by the gripper

+Notes

  • Ejector with digital vacuum switch 20.021 for process monitoring (Index „-VA“)
  • The vacuum switch can be freely adjusted after mounting the ejector

+When ordering please specify

+Dimensions

  • a = Silencers for nozzle Ø 1.2 or 1.5 mm
  • b = Silencers for nozzle Ø 2 - 2.5 or 3 mm
  • c = Manual vacuum and blow-off control
  • d = Mounting Ø 4.2 mm
  • e = Adjusting blow-off power
