Custom Design Options
Temperature sensors
Integrating sensors into heaters simplifies your assembly
operations by providing a gradient-free system with excellent
temperature control. The sensor sits in a window of the heating
element. It reacts to temperature changes in the component
beneath the heater, yet remains close to the heating element
itself. This tight coupling of heater, sensor, and heat sink can
greatly improve heating control and accuracy.
Sensors can be electrically connected via leadwires or
flex circuitry.
Most heater/sensors are custom designed. Minco recom-
mends prototyping with standard heaters and Thermal-
Ribbon™ sensors. Get more information on Thermal-Ribbon
sensors in the "Sensors, Controllers & Accessories" section.
