Bimetallic Strip Truflex P675R For Heat-Sensitive Components
Common Name: 5J20110, Telcon200, 1200
Size:Thickness min 0.1mm
Width max 125mm
Application:The material is mainly in automatic control devices and instrumentation (eg: exhaust thermometers, thermostats, voltage regulators, temperature relay, automatic protection switching, diaphragm meters, etc.) make temperature control, temperature compensation, current limit, temperature indicator and other heat-sensitive components.
Feature: The basic characteristics of Thermostat Bimetallic is bending
deformation with temperature changes, resulting in a certain
moment.
Thermostat Bimetallic Strip expansion coefficient is different from
the two or more layers of metal or alloy along the entire contact
surface firmly bonded, having a temperature-dependent shape change
occurs thermosensitive functional composites. Wherein the higher
expansion coefficient of the active layer is a layer called a low
coefficient of expansion of the layer is named passive layer.
