Delock M4 Threaded NTC Temperature Sensor Cable, 10 kΩ, 1 m, FEP Insulated, 2 Open Wire Ends

For precision temperature measurement in tight spaces, the Delock 91808 stands out with its compact M4 threaded stainless steel probe and high-accuracy NTC thermistor. Unlike generic bead sensors that require additional mounting hardware, this cable integrates a robust M4 screw-in probe for secure attachment to heatsinks, motor housings, or industrial fixtures. The 1 m cable uses FEP insulation, which resists temperatures up to 150 °C and aggressive chemicals, making it suitable for demanding environments where PVC would fail. Two open wire ends provide flexible connection to your own electronics, data loggers, or control boards.

Highlights

• M4 threaded stainless steel probe for easy and reliable mounting
• NTC thermistor with 10 kΩ resistance at 25 °C and B25/85 value of 3977 K
• FEP insulated wires withstand high temperatures and chemical exposure
• 1 m cable length with two open wire ends for custom termination
• Wide operating range from -40 °C to 150 °C

In daily use

Install the sensor by screwing the M4 probe into a pre-tapped hole on the target surface. The stainless steel body ensures good thermal contact and mechanical stability. Route the FEP wires away from hot or moving parts; their insulation remains flexible and non-degrading even at elevated temperatures. Connect the two open ends to your measurement circuit—no connector means you can trim to exact length or crimp your preferred terminals. Ideal for PC water-cooling loops, 3D printer hotends, HVAC systems, and laboratory equipment.
