New Product Infrared Thermosensor ES1C Achieve Superior Environmental Resis- tance and a Wide Measurement Range of 0 to 400C. Flexible placement with slim cylindrical shape and long focus with a distance of 500 mm and area diameter of 80 mm. The SUS body and silicon lens resist ambient operating tempera- tures of up to 70C and resist dust and water to the equivalent of IP67. Fast measurement with high-speed response of 100 ms/90%. Strong resistance to noise with output of 4 to 20 mA. Refer to the Safety Precautions on page 6.
