Product Overview

The CWF series NTC Thermistor Probes from Cantherm offer precision temperature measurement solutions. Designed for a wide range of applications, these probes feature a high-reliability NTC thermistor insulated with heat-conductive, water-resistant materials and potted into various probe bodies. They are available in five basic enclosure styles, including ethoxyline dipped, metal housing, plastic body, sheet metal attachment fixtures, and custom probes. CWF thermistors are suitable for applications requiring accurate temperature sensing, regulation, and control in diverse environments, from household appliances to automotive electronics and industrial controllers. Key advantages include small size, fast response times, long-term stability, excellent tolerance, and robust construction for insulation and impact resistance.
