The document describes a non-contact infrared temperature sensor with an environmental rating of IP65 (NEMA-4). The sensor has an ambient temperature range of -20 to 75°C, a storage temperature range of -20 to 85°C, and a relative humidity range of 10-95%. It features 0-5V or 0-10V voltage outputs, with the option for RS232 digital output or programmable functional input. The sensor has a scalable temperature range, a spectral range of 8-14μm, an optical resolution of 10:1, and a 1.2mm CF lens. It has a fast response time and high accuracy, making it suitable for industrial temperature measurement and monitoring.
