Specification notes
Q1: What is the FD-A300P Series?
A: The FD-A300P Series is a fiber-type hot metal detection sensor that detects infrared energy radiated from heated steel and other hot materials without requiring a separate light emitter.
Q2: Which models are available in the FD-A300P Series?
A: The current lineup consists of FD-A300P, FD-A300PH, FD-A300PC, and FD-A300PM, mainly differing in control output type.
Q3: What hot-material temperatures can the FD-A300P Series detect?
A: With an OHA optical head and FG2 2 m fiber, and when the target is larger than the detection field, the reference low-temperature range is 350–800°C and the high-temperature range is 490–1300°C.
Q4: How are the low- and high-temperature ranges selected?
A: The sensor provides two temperature ranges that can be switched using an external input.
Q5: What are the differences among FD-A300P, FD-A300PH, FD-A300PC, and FD-A300PM?
A: FD-A300P uses a mini power relay output, FD-A300PH a signal relay output, FD-A300PC a solid-state output, and FD-A300PM a PhotoMOS relay output. Their response times and output ratings also differ.
Q6: Does the FD-A300P Series require manual sensitivity adjustment?
A: Auto sensing can automatically set the operating threshold according to received light intensity during hot-material detection. A manual setting mode is also available.
Q7: Can the FD-A300P Series switch between Light-ON and Dark-ON?
A: Yes. Light-ON and Dark-ON are selectable by DIP switch, with Light-ON as the default setting.
Q8: Does the FD-A300P Series store previous received light levels?
A: Yes. It can store the maximum received light intensity from the eight most recent hot-material detections for later review.
Q9: Can the FD-A300P Series operate in high-temperature environments?
A: The optical head and fiber can operate from -25 to +200°C, while the amplifier operates from -25 to +50°C. The protective structure is IP66.
Q10: What applications is the FD-A300P Series suitable for?
A: It is suitable for non-contact presence, passage, and position detection of heated steel and other hot materials using their emitted infrared energy.
