In addition, the sensor’s smooth surface and minimal crevices ensure easy cleaning; its housing is fully epoxy encapsulated to eliminate internal air cavities that can lead to condensation inside sensors during temperature cycling. The all-plastic sensor also features ultrasonically-welded joints for a durable seal that can withstand thermal shock with greater reliability than comparable metal sensors. This ensures reliable operation in temperatures ranging from -40 to +70 °C (-40 to 158 ºF). Sensor setup and alignment are made simple by a bright, visible red emitter (all models except infrared). The highly visible output and dual-function power and stability indicators make the sensors easy to use and troubleshoot.
