The Atlas Copco 1089-0574-46 is a genuine temperature sensor specified for air treatment equipment — such as dryers or downstream filtration systems — rather than the compressor body itself. This distinction matters when troubleshooting: if you’re seeing a temperature-related fault, confirming whether the affected component is the compressor or a connected air treatment unit will help narrow down which sensor is actually at fault.
We couldn’t confirm the specific signal output type for this exact part number from available sources — send us your equipment’s nameplate and we’ll verify the correct specification before you order.

Compatibility Depends on Controller Generation,Not Appearance
A sensor that looks physically identical to your old one may still be the wrong part if it outputs a different signal type or covers a different measuring range than what your controller generation expects. Atlas Copco has revised sensor specifications across controller generations (e.g.,Elektronikon Mk4 vs Mk5)even when the physical connector hasn ‘t changed — the compressor may power on and appear to run normally while actually reading incorrect values,or no value at all,from a mismatched sensor.Confirming your controller generation before ordering is more reliable than matching by visual comparison alone.
Sensors Degrade Gradually,and Rarely Announce It
Unlike a mechanical part that fails visibly,a sensor ‘s accuracy can drift over years of service without triggering any alarm — the controller has no way to know the reading it ‘s receiving has becomes lightly wrong,only that a reading exists. This matters most for sensors tied to protective functions (like discharge temperature),where a drifted reading could delay a shutdown that should have happened,or trigger one that shouldn ‘t have.If a compressor is behaving inconsistently with what its display shows,an aging sensor is worth ruling out even if there ‘s no fault code pointing to it directly.
Handling Before and During Installation
Sensors are more sensitive to installation conditions than mechanical parts.A few things worth keeping in mind:
– Avoid over-tightening threaded sensors: excessive torque can damage the internal element even if the housing looks intact
– Keep connectors and pins free of moisture or contamination before connecting,especially in humid or outdoor installation environments
– Route cabling away from high: vibration areas where possible,as repeated flexing at the connection point is a common cause of intermittent signal loss
– Power down the compressor before installation: connecting or disconnecting sensors on a live circuit risks damaging both the sensor and the controller input
Common Questions
How do I know if this sensor matches my controller?
Send us your controller generation (e.g.,Elektronikon Mk4/Mk5) and the compressor model — signal type and measuring range must match,not just the physical connector.
Do sensors need periodic replacement even if there 's no fault?
Not typically on a fixed schedule,but sensors tied to protective functions are worth including in major service intervals,since gradual drift isn ‘t self-announcing.
The compressor is showing a reading,but it seems wrong — could the sensor be at fault?
Yes.A drifting or partially failed sensor can continue sending a signal without triggering a fault code,so an incorrect reading doesn ‘t rule out a sensor issue.
Should I keep a spare sensor on hand?
Many customers do,particularly for sensors tied to protective shutdown functions — a low-cost spare in stock can prevent an unplanned downtime scenario from turning into an extended one while waiting on a replacement.
Are these genuine Atlas Copco parts?
Yes.Parts are sourced through Atlas Copco distributor channels.
What is the typical lead time?
Common consumables (filters, oil) typically ship within about 1 week. Lead time for other spare parts depends on stock availability — please contact us for a confirmed schedule.
Do you inspect parts before shipment?
Yes. We provide full photos and video of the actual item before shipment, and confirm everything is correct with you prior to dispatch.
What shipping options are available?
If you have your own freight forwarder, we can ship to them directly. If not, we can provide shipping options based on your preference.
