For the version summoned by Grineer units in any Mission, see Regulator.
Detects intruders.

Sensor Regulators are a variant of the Grineer Regulator drone that appear in Spy and Sealab Sabotage missions. Unlike normal Regulators, that simply float in place, Sensor Regulators are mobile, and will move to patrol a location in search of enemies. While unarmed, Sensor Regulators are equipped with cameras that will trigger an alarm upon seeing a player or taking damage, alerting nearby Grineer and activating the relevant security measures (such as a Data Vault's purge sequence).


  • Their sensor beams do pass through paned windows.
  • It can be possible to pass underneath their sensor beam without triggering the alarm.
  • Damage to Sensor Regulators taken from companions does not seem to always trigger the alarm.
  • Sensor Regulators are revealed on the minimap using Enemy Sense or Enemy Radar.
  • Sensor Regulators do not count towards Exterminate objectives. They also do not trigger or remove Stealth Attack Affinity Bonuses, being considered an environmental object instead of a unit.
  • Sensor Regulators will not trigger the alarm if they are destroyed with a single hit. Silent, high-damage weapons such as the Dread2 Dread, CrpBFG Opticor, or PrimeBowM Paris Prime are all ideal for efficiently dealing with them; other high-damage weapons (e.g. SMMarelok Vaykor Marelok, PrimeLex Lex Prime) can also use Hush or Suppress for a similar effect.
    • Note that the alarm will trigger if the Regulator takes damage but is not instantly destroyed by that singular burst of damage, so sustained weapons such as the Gammacor Gammacor and SynoidGammacor Synoid Gammacor should be avoided despite their high damage output.

Utilizing AbilitiesEdit

Sensor Regulators will not raise alarms if:

  • Affected by NyxIcon272 Nyx's MindControl130xDark Mind Control, even when the player passes the sensor beams;
  • Stunned by TrinityIcon272 Trinity's WellOfLife130xDark Well Of Life;
  • Affected by ExcaliburIcon272 Excalibur's RadialBlind130xDark Radial Blind or EquinoxIcon272 Equinox's Nightform's Rest even if the sensor beams are passed. They will, however, keep moving as normal.
  • Affected by NekrosIcon272 Nekros's Terrify130xDark Terrify – if the player passes the beam the Regulator will even attempt to turn and move away from him;
  • The player is cloaked in any way, for example with LokiIcon272 Loki's Invisibility130xDark Invisibility, AshIcon272 Ash's SmokeScreen130xDark Smoke Screen, IvaraIcon272 Ivara's Cloak Arrow and/or Prowl130xDark Prowl, Shade's Ghost or Huras Kubrow's Stalk;
    • (the stun portion of Smoke Screen will neither stagger nor alert Regulators);
  • Teleported somewhere using Loki's SwitchTeleport130xDark Switch Teleport or NovaIcon272 Nova's WormHole130xDark Worm Hole. It will then try to get back to its initial route as fast as possible;
  • It sees certain ability manifestations such as ChromaIcon272 Chroma's Effigy130xDark Effigy, Loki's Decoy130xDark Decoy, SarynIcon272 Saryn's Molt130xDark Molt, Nekros's ShadowsOfTheDead130xDark Shadows Of The Dead or even a HydroidIcon272 Hydroid submerged in its Undertow130xDark Undertow;
  • It is damaged by certain abilities that deal damage over time such as Undertow, Shadows of the Dead or Effigy, even if they are not able to one-shot the Regulator with the first tick;
  • RhinoIcon272 Rhino uses RhinoCharge130xDark Rhino Charge to bypass the sensor beams
  • Limbo uses Banish130xDark Banish on the Sensor Regulator to destroy it in one shot. Failing to destroy it will lead to the alarm triggering.
  • Limbo uses Stasis130xDark Stasis and walks past the sensors.
  • FrostIcon272 Frost uses Freeze130xDark Freeze to freeze the regulator, even if the freeze does not kill it. However, shooting it will still trigger alarms. Utilize the freeze to bypass it quickly.

The alarms will be triggered however if:

  • A player in the Rift Plane from LimboIcon272 Limbo's Rift Walk or Banish130xDark Banish passes the beam;
  • Limbo manually ends Stasis130xDark Stasis after walking past the sensors.
  • It is damaged and moved around by BansheeIcon272 Banshee's SonicBoom130xDark Sonic Boom;
    • (A Silence130xDark Silenced Sonic Boom will damage and kick the Regulator around, but not always cause it to trigger the alarms);
  • AshIcon272 Ash uses Teleport130xDark Teleport on a Regulator, even while under the effect of Smoke Screen;
  • Hit but not one-shotted by the initial damage tick of Equinox's dayform's Maim;
  • Stunned and damaged by Trinity's EnergyVampire130xDark Energy Vampire;
  • ExcaliburIcon272 Excalibur uses SlashDash130xDark Slash Dash to pass the beam;
  • Sucked into VaubanIcon272 Vauban's Vortex130xDark Vortex; or
    • His Bastille130xDark Bastille will have no effect except applying its particles, neither keeping them in place, nor disabling the alarms.
  • Vauban places a bounce pad directly on the Regulator.

Notes Edit

  • An Eximus variant was introduced in Update 18.0. These Sensor Regulators have 100% more armor and 200% more health, making them far more durable than standard versions. These units start spawning in Tier 2 (Level 15-25) Spy missions, and spawn more frequently in Tier 3 (Level 25+).


  • On some occasions, attempting to damage the drones from behind will cause them to not trigger the alarms.
  • When viewed within their Codex, the Sensor Regulator will oddly slowly fall backwards until eventually falling to the ground, however the thruster effects will still remain in place.
  • The Sensor Regulator can be scanned indefinitely, resulting in consuming a Codex Scanner even if the entry is completed. This also applies to the Helios's Investigator precept.
