Delock Temperature Sensor Cable M4 NTC 10 kOhm B25/50 3950K 1 m PVC Black

Precision temperature monitoring in tight spaces demands a sensor that fits without compromise. The Delock 91810 answers with an M4 threaded probe and a slim 2.8 mm PVC cable, built for industrial and DIY thermal management where standard sensors are too bulky or fragile. Its NTC thermistor delivers a stable 10 kOhm at 25 °C and a B25/50 constant of 3950K, giving you predictable, repeatable readings across a wide -40 °C to 105 °C range.

Highlights

• M4 threaded sensor head for secure mounting in threaded holes or brackets
• NTC thermistor with 10 kOhm resistance at 25 °C and ±1 % tolerance
• B-value 3950K (25/50 °C) for accurate temperature-to-resistance conversion
• 1 m round PVC cable with two open wire ends for flexible connection
• Operating range from -40 °C to 105 °C, suitable for harsh environments
• RoHS compliant, insulation resistance >100 MOhm, dielectric strength 1500 V AC

In daily use

Install the M4 probe into a heatsink, pipe clamp, or enclosure wall, then route the black PVC cable to your controller, ADC, or monitoring board. The bare wire ends accept soldering, crimping, or screw terminals, so you can integrate the sensor without proprietary connectors. The round cable resists abrasion and stays flexible even in cold conditions, while the 2.8 mm diameter slips through narrow conduits. Whether you are logging battery temperatures, regulating a 3D printer hotend, or protecting a motor winding, this sensor provides the data you need without drift or guesswork.
