Similar in nature to Corpus Laser Barriers, the Grineer Sensor Bar is located above some doorways in the Grineer Galleon tileset. It projects a field across the opening of the door which will deal damage and inflict a DmgMagneticSmall64 Magnetic proc, draining energy and temporarily reducing shields. Destroying the green sensor light will disable it, allowing safe entry.


  • Will respawn when host migration occurs, resetting all Sensor Bar traps.
  • Sensor Bars do not discriminate targets. Thus they will inflict a small amount of DmgMagneticSmall64 Magnetic damage and proc anything passing through regardless if it is friend or foe. However, since they lack shielding most Grineer units will be unaffected by this.
    • On lower levels Butchers will often die upon entering the doorway (because of the magnetic damage), cluttering the path with Pickups as a result.
  • Unlike its Corpus counterpart, the Laser Barrier, it can not be bypassed by sliding, however skills like IronSkin130xWhite Iron Skin and RhinoCharge130xWhite Rhino Charge will prevent the magnetic proc.
  • Occasionally, the placement of doors near some areas causes the green light to be covered up, and requires players to stand directly against the door to be able to shoot the light. 
  • Sensor Bars are vulnerable to Grineer fire, such as the AoE blast of a Bombard or Napalm.
  • Unlike the Corpus variant, the magnetic field is projected at all times, making the moving green beam unnecessary except to warn players of its existence.
  • While normally found only on missions with the Grineer Galleon tileset and only on circular doors, a larger version of the Sensor Bar using wide gates can be found on Grineer Shipyard and Grineer Asteroid Rescue missions, guarding the entrance to the holding cells.
    • The Grineer Spy Data Vault that holds a Corpus Lynx is guarded by a wide gate with a Sensor Bar.


  • This is the first Grineer anti-passage counter measure to be used.
  • Added in Update 12.4 (2014-03-05), along with the now removed Broken Lights (which were replaced with Arc Traps)
