Features

Heat-resistant sensing up to 200°C: The optical head and fiber contain no electronic components and can operate from -25 to +200°C while the amplifier units are installed away from the high-temperature area.
Detection range up to 40 m: With an FG2 2 m fiber, the through-beam system provides up to 40 m detection, with available ranges from 10 to 40 m depending on fiber length.
Five-level received light indication: The receiver displays received light intensity in five levels, making optical alignment and detection-margin checking easier.
Integrated self-check functions: The transmitter provides an alarm if light emission fails, while the receiver outputs a safety alarm when optical misalignment or lens contamination reduces received-light margin.
Three control output options: FTR10A, FTR10AH, and FTR10AC provide mini power relay, signal relay, and solid-state outputs with different response times.

Specification notes

Detecting distance decreases as fiber length increases, from 40 m with an FG2 2 m fiber to 10 m with an FG30 30 m fiber.
FTR10A, FTR10AH, and FTR10AC mainly differ in control output type and response time. Their power supply, optical performance, safety alarm, and environmental specifications are common.
The optical head and fiber can operate at ambient temperatures up to +200°C, while the transmitter and receiver amplifier units are rated for −25 to +55°C.

FAQ

Q1: What is the FT10A Series?
A: The FT10A Series is a through-beam heat-resistant fiber-type cold metal detector for presence, passage, and position confirmation of steel and other materials in heavy-industry equipment.

Q2: Which models are available in the FT10A Series?
A: The FTL10A transmitter can be paired with FTR10A, FTR10AH, or FTR10AC receivers, which mainly differ in control output type and response time.

Q3: What is the maximum detecting distance?
A: The maximum detecting distance is 40 m when using an FG2 2 m fiber.

Q4: Does fiber length affect detecting distance?
A: Yes. Detecting distance decreases with longer fibers, from 40 m with FG2 to 10 m with FG30.

Q5: Can the sensing section operate in high-temperature environments?
A: Yes. The optical head and fiber can operate from -25 to +200°C, while the amplifier units operate from -25 to +55°C.

Q6: What are the differences among FTR10A, FTR10AH, and FTR10AC?
A: FTR10A uses a mini power relay, FTR10AH a signal relay, and FTR10AC a solid-state output. Their response times are 15 ms, 5 ms, and 3 ms maximum respectively.

Q7: How is optical alignment checked?
A: The receiver provides five-level received-light indication for checking optical alignment and received-light margin.

Q8: What do the self-check functions monitor?
A: The transmitter provides an alarm if light emission fails, while the receiver generates a safety alarm when misalignment or lens contamination reduces received-light margin.

Q9: What is the protection rating of the FT10A Series?
A: The amplifier units are rated IP66, while the optical head and fiber can be installed in high-temperature sensing areas within their specified conditions.

Q10: What applications is the FT10A Series suitable for?
A: It is suited for long-range presence and passage detection of steel in steel mills and heavy-industry equipment, especially where the sensing section must be installed near high-temperature machinery.
