Description

The CWF series NTC Thermistors are supplied in 5 basic styles of enclosures designed to facilitate installation in a wide variety of applications. PVC leads are applied to a precision, high-reliability NTC thermistor, insulated with heat conductive water resistant materials and potted into any of a wide variety of probe bodies. CWF thermistors are also available with custom housings or custom lead lengths for remote sensing and temperature control in difficult conditions.

Application

• Heating, ventilation & air conditioning
• Temperature regulation and measurement
• Automotive electronics
• Water heaters
• Household appliances such as refrigerators,
water coolers, dishwashers and many others
