## Long description

The DeLOCK 91807 is a high-quality 1-meter temperature sensor extension cable designed for precise thermal monitoring in demanding environments. Featuring an M4 ring cable lug for secure mounting and two open wire ends for versatile connectivity, this cable ensures reliable signal transmission. It is constructed with FEP-insulated single wires, offering excellent durability and resistance to environmental factors, making it a dependable choice for industrial and laboratory temperature sensing tasks.
Advantages
The primary benefit of this sensor cable is its robust construction and high-precision thermal monitoring capabilities. The FEP insulation provides superior protection against heat and chemical exposure, ensuring long-term stability in various operating conditions. The M4 connector allows for straightforward and secure mechanical attachment to heat sinks or other surfaces, while the 1-meter length provides sufficient reach for complex system configurations. Its standardized B25/50 3950K characteristic ensures compatibility with a wide range of monitoring equipment and control systems.
Suitable for
Battery pack safety monitoring
Battery Management Systems (BMS)
Power supply thermal regulation
Industrial temperature sensing applications
Laboratory equipment monitoring
When it may not be suitable
This cable is not intended for high-voltage power transmission or applications requiring extreme mechanical stress beyond standard thermal monitoring. It is also not suitable for environments where the M4 mounting point is incompatible with the target surface or where a different sensor characteristic is required by the control hardware.
Key specifications
Cable length: 1 meter
Connector type: M4 ring cable lug
Wire ends: 2 open wire ends
Insulation material: FEP
Characteristic: B25/50 3950K
Color: Black
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 heat transfer. Connect the two open wire ends to your monitoring device or controller, ensuring correct polarity if applicable. The tinned stranded wires are designed for easy soldering or terminal block connection. Once connected, verify the sensor reading against a known reference temperature to ensure accurate calibration within your system.
What to consider before purchase
Verify that your monitoring device supports the B25/50 3950K NTC characteristic.
Ensure the M4 mounting point is available on your target hardware.
Check if the 1-meter cable length is sufficient for your specific installation layout.
Confirm that the open wire ends are compatible with your existing connection method, such as soldering or crimping.
Usage recommendations
For optimal measurement accuracy, ensure that the M4 ring lug is mounted firmly against the heat source. Avoid sharp bends or excessive tension on the cable to maintain the integrity of the FEP insulation and internal wiring.
