Range: −55°C to 250°C Packaged in Extra Small Ring Lug APPLICATIONS Use #2 imperial or M2.5 metric screw to mount the thermistor assembly onto a smooth metal surface of the object for which the temperature needs to be measured. The thermistor lead wires are made of plain copper, make sure that they do not touch each other, nor any other electrically conductive objects. For high precision applications, use a cover which is made of thermal isolation material to cover the thermistor area, see Figure 2. In this way, the air flow will not affect the temperature sensing accuracy. Object Temperature sensing for laser diodes, optical components, etc. Cover DESCRIPTION The ATH10KL2 is a thermistor assembly with a glass encapsulated thermistor packaged in an extra compact ring lug. Comparing with conventional assemblies containing epoxy encapsulated thermistors, ATH10KL2 presents higher long term stability, higher reliability and wider temperature range. In addition, it has a small size and short response time. The ATH10KL2 can be used to measure the temperatures of laser diodes, optical components, etc., with high accuracy and long term stability.
