Delock cavo sensore di temperatura M4 NTC termistore con 2 terminali aperti, 10 kOhm, B25/85 3977K, 1 m, PVC, nero

Accurate temperature monitoring in industrial and embedded systems often fails due to unreliable sensor connections or incompatible probe mounting. The Delock 91811 solves this by providing a robust M4 threaded NTC thermistor probe with a 1 m PVC cable and two open wire ends for flexible integration. Its precise 10 kOhm resistance at 25°C and B25/85 value of 3977K ensure consistent, repeatable measurements across a wide operating range from -25 °C to 85 °C.

Who is it for

This sensor cable is ideal for engineers, technicians, and hobbyists who need to add temperature sensing to microcontroller projects, 3D printers, HVAC systems, battery packs, or any application requiring a durable screw-mounted NTC thermistor. The open cable ends allow direct connection to terminal blocks, connectors, or custom circuitry.

Main features

• M4 threaded probe for secure mounting on metal surfaces, heat sinks, or enclosures
• NTC thermistor with 10 kOhm resistance at 25 °C (±1%) for standard measurement circuits

Tips

For best thermal contact, apply a small amount of thermal paste between the M4 probe and the surface being measured. When connecting the open ends, ensure proper polarity if your circuit requires it; otherwise, the NTC thermistor is non-polarized. Use heat-shrink tubing to insulate solder joints and protect against moisture or short circuits.
