DeLOCK 91811 Temperature Sensor Extension Cable M4 with Open Ends 1m

The DeLOCK 91811 is a high-quality NTC temperature sensor extension cable designed for precise thermal monitoring in various technical environments. Featuring an M4 ring cable lug for secure mounting and a 1-meter length, this cable provides a reliable interface for temperature measurement systems. The cable is constructed with a durable PVC coating, ensuring flexibility and protection for the internal wiring, making it an essential component for integrating sensors into complex electronic assemblies.

Advantages

This temperature sensor offers exceptional versatility due to its standardized M4 mounting interface, which allows for quick and stable attachment to heat sinks, battery terminals, or chassis components. The use of high-quality tinned stranded wire ensures excellent electrical conductivity and long-term durability. Its robust PVC insulation provides resistance against environmental factors, while the 1-meter length offers sufficient reach for most standard industrial or DIY electronics configurations, facilitating clean and organized cable management.

Suitable for

• Battery pack safety monitoring
• Battery Management Systems (BMS)
• Power supply thermal regulation
• Industrial temperature measurement systems
• DIY electronics and prototyping projects

When it may not be suitable

This sensor is not intended for use in environments with extreme chemical exposure or high-pressure steam, as the PVC insulation may degrade under such conditions. It is also not suitable for applications requiring submersion in corrosive liquids or environments exceeding the specified thermal operating range.

Key specifications

• Cable length: 1 meter
• Mounting type: M4 ring cable lug
• Cable material: PVC-coated tinned stranded wire
• Sensor type: NTC
• Design: Round cable with two open ends

How to use

To install the sensor, securely fasten the M4 ring lug to the surface or component where temperature monitoring is required, ensuring a clean metal-to-metal contact for accurate thermal transfer. The two open ends of the cable should be connected to your measurement device or controller according to the specific wiring diagram of your system. Ensure that the connections are properly insulated and strain-relieved to prevent mechanical stress on the sensor cable during operation.

What to consider before purchase

• Verify the M4 mounting point compatibility on your target device.
• Ensure the NTC sensor resistance characteristics match your controller requirements.
• Check if the 1-meter cable length is sufficient for your specific installation layout.
• Confirm that the operating temperature range of the sensor aligns with your application needs.

Usage recommendations

For optimal measurement accuracy, ensure the M4 ring lug is tightened firmly against the heat source and consider using thermal paste if necessary to improve heat transfer. Always route the cable away from high-voltage lines to minimize electromagnetic interference.
