## Long description

The DeLOCK 91809 is a high-quality 1-meter temperature sensor extension cable designed for precise thermal monitoring in technical and industrial environments. Featuring an M4 ring cable lug for secure mounting and open wire ends for versatile connectivity, this sensor utilizes FEP-insulated stranded wires to ensure durability and reliable performance. With a B25/85 3435K resistance value, it provides consistent and accurate data transmission for various thermal management systems.
Advantages
This temperature sensor offers exceptional flexibility for system integration due to its robust construction and high-quality materials. The FEP insulation provides excellent resistance to environmental factors, ensuring long-term stability even in demanding conditions. Its M4 connector allows for straightforward mechanical attachment to heat sinks or battery housings, while the tinned wire ends facilitate easy soldering or terminal block connection, making it an ideal choice for professional technical setups.
Suitable for
Battery pack safety monitoring
Battery Management Systems (BMS)
Power supply thermal regulation
Industrial equipment temperature tracking
Custom thermal sensor configurations
When it may not be suitable
This sensor is not intended for use in high-voltage electrical circuits or environments where the cable may be exposed to extreme mechanical stress or sharp edges that could compromise the FEP insulation. It is also not suitable for direct immersion in corrosive liquids or applications requiring specialized waterproof sealing beyond the standard cable construction.
Key specifications
Cable length: 1 meter
Connector type: M4 ring cable lug
Wire insulation: FEP (Fluorinated Ethylene Propylene)
Resistance value: B25/85 3435K
Termination: Open wire ends (tinned)
How to use
To install the sensor, securely fasten the M4 ring lug to the surface or component requiring temperature monitoring using a compatible screw. Ensure the contact surface is clean to allow for optimal thermal conductivity. Route the 1-meter cable away from moving parts or heat sources that exceed the material's temperature rating. Connect the open wire ends to your measurement device or controller, ensuring correct polarity and secure electrical contact according to your specific hardware requirements.
What to consider before purchase
Verify that the M4 mounting point is compatible with your equipment.
Ensure your controller or BMS supports the B25/85 3435K resistance curve.
Check if the 1-meter cable length is sufficient for your installation layout.
Confirm that the operating temperature range of the sensor meets your application needs.
Usage recommendations: Always perform a calibration check after installation to ensure the sensor readings align with your system's expected thermal parameters. Avoid bending the cable at sharp angles near the M4 connector to prevent internal wire fatigue.
