The Keyence FT-H20 is a mid-range digital infrared temperature sensor head designed for non-contact temperature measurement in industrial automation applications. This sensor head is part of the FT Series and utilizes a thermopile detecting element to measure temperatures from 0 to 500°C with a displayable range extending from -50 to +520°C. The FT-H20 features a dual-point visible red laser targeting system that clearly indicates the measurement area, making installation and alignment straightforward. With high repeatability of ±0.5°C and adjustable emissivity correction from 0.10 to 1.99, the sensor provides accurate and consistent temperature readings across various surface materials. The compact, rugged construction includes a reinforced glass plastic case and germanium infrared collector lens, suitable for demanding industrial environments. The sensor head must be paired with a compatible amplifier unit such as the FT-50AW or FT-55AW for operation.
