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.
