## Long description

Alphacool 18357 is an SMD temperature sensor with an approximate 90 cm cable and a 2-pin connector. It is compatible with various Alphacool devices and can be used with other monitoring systems that support a 2-pin SMD sensor interface.
Advantages
The sensor offers a compact SMD design, a long flexible cable for convenient routing inside computer cases, and simple 2-pin connectivity for straightforward integration with compatible controllers. Its lightweight construction allows placement without adding noticeable bulk to cooling assemblies.
Suitable for
Monitoring coolant or air temperature inside PC cooling loops
Integration with Alphacool controllers such as aquaero and aquastream models
Replacement or extension of existing temperature sensors in custom cooling setups
Key specifications
Sensor type: SMD temperature sensor
Connector: 2-pin connector
Cable length: approximately 90 cm
Weight: approximately 6 g
How to use
Place the SMD sensor at the location where temperature measurement is required, secure it in position if necessary, and connect the 2-pin connector to the compatible monitoring or controller input. Ensure the cable routing avoids sharp edges or moving parts and that the connector is fully seated to obtain reliable readings.
Usage recommendations
Use the sensor with compatible Alphacool controllers (for example, aquaero or aquastream series) or other devices that support a 2-pin SMD temperature input. Avoid exposing the sensor to direct liquid flow without proper insulation; fasten the cable to prevent strain on the connector.
