KEYENCE FT-50AP
KEYENCE FT-50AP
Description:
The KEYENCE FT-50AP is a DIN rail mounted amplifier unit for the FT Series digital infrared temperature sensors. This PNP output amplifier processes signals from compatible FT sensor heads to provide non-contact temperature measurement with a dual-color LED display, analog output, and programmable switching outputs. It is commonly used in manufacturing, packaging, food processing, and industrial automation applications where accurate temperature monitoring without physical contact is required. The FT-50AP has been discontinued but remains widely used in existing installations.
Applications:
The KEYENCE FT-50AP is designed to measure surface temperature without contacting the target object. It is commonly used in metal processing, plastics manufacturing, packaging equipment, food processing, and industrial automation systems where temperature must be monitored continuously and accurately. The amplifier supports multiple FT Series sensor heads, allowing measurements at distances up to 3000 mm depending on the selected sensor model.
