Product Description
The KEYENCE FT-50AP is a DIN-rail mounted amplifier unit (PNP output type) for the FT Series Digital Infrared Temperature Sensor system. It provides non-contact infrared temperature measurement with a dual-color 7-segment LED display, dual PNP open-collector control outputs, and a 4–20 mA analog output. The FT-50AP is the PNP variant of the FT-50A, designed for European and global industrial automation applications, and is noted as discontinued by the manufacturer.
