SMSCom Mk2 6.5-Amp Sensor - Replacement Probe for Smart Fan Controllers
Best for: owners of the SMSCom 6.5-Amp Mk2 Plug-In Smart Fan Speed Controller who need a replacement or remote-placed temperature sensor.
Our thoughts
Smart control features without the usual premium pricing. This sensor is a straightforward fix for a faulty probe, or a handy upgrade if you want to move your temperature reading point away from the controller body itself. Performs consistently when you need it to.
The SMSCom Mk2 6.5-Amp Sensor is a replacement for a damaged or faulty sensor on a SMSCom 6.5-Amp Mk2 Plug-In Smart Fan Speed Controller. It can also be used as an upgrade to the SMSCom 6.5-Amp Mk2 Plug-In Smart Fan Speed Controller so that it can take readings remotely, away from the controller unit itself. The probe feeds a continuous temperature reading back to the controller's internal software, which adjusts fan speed automatically to hold your set target.
How it compares
It's a targeted fix rather than a full unit replacement.
- vs the 2m probe supplied as standard with many SMSCom units: this Mk2 sensor runs to 3m, giving more placement flexibility
- vs generic NTC probes: matched calibration for the SMSCom Mk2 controller, so there's no accuracy drift from using a mismatched part
- vs replacing the whole controller: considerably cheaper than buying a new SMSCom unit when it's just the probe that's failed
In plain terms: fix the actual fault rather than paying for a whole new controller.
Usage guidance
Diagnosing a fault
If the fan runs erratically or the display shows odd readings, the probe is often the cause rather than the controller itself.
Fitting
Unplug the old probe and plug this one into the sensor socket - no recalibration is required.
Remote placement
Fit this even if your existing probe still works, to move the temperature reading point further from the controller body and closer to the canopy.

Our take
Reliable performance without overpaying for features you don't need. If your Mk2 controller is misbehaving and the probe looks like the culprit, this is the cheaper, sensible fix before you start thinking about a full replacement.
Worth picking up if you want equipment you can rely on without the cost of a whole new controller.
