NTC Temperature Sensor for Refrigerator Temperature Controlling Defrost Sensor

Short Description:

Introduction:NTC Temperature Sensor

NTC temperature sensor is an NTC thermistor after the wire welding, encapsulate into a different probe and then use an epoxy seal. The NTC temperature sensor retains all the features of the NTC thermistor. After the optimization of the injection and cooling stages, will be made into a complete product, mass production is a continuous cycle of this processing step produced. Molding cycle according to product size, probe material and product design is different, a complete temperature sensor requires several different parts and processes.

Function: temperature sensor

MOQ:1000pcs

Supply Capacity:     300,000pcs/month

Working Principle

NTC temperature sensor working principle is the same with the NTC thermistor, the principle is: the resistance value of the resistance with increasing temperature decreases rapidly. It is usually composed of 2 or 3 kinds of metal oxides, and in the high temperature furnace forging into a precision ceramic sintered body. The actual size is very flexible, they can be as small as .010 inches or very small diameter. The maximum size is almost unlimited, but usually applies for half an inch or less.

Craft Advantage

We operate additional cleavage for the wire and pipe parts to reduce the flow of epoxy resin along the line and reduce the height of the epoxy. Avoid gaps and breakage bending of wires during assembly.

Cleft area effectively reduce the gap at the bottom of the wire and reduce the immersion of water under long-term conditions.Increase the reliability of the product.
