Specification notes
Q1: What is TAKEX FTH7BC?
A: FTH7BC is a heat-resistant threaded through-beam fiber optic unit rated for temperatures up to +105°C, designed for non-contact object detection near high-temperature equipment.
Q2: What detection method does FTH7BC use?
A: FTH7BC uses through-beam detection by monitoring changes in light between the transmitter and receiver to detect object presence or passage.
Q3: What is the maximum operating temperature of FTH7BC?
A: The ambient operating temperature range is −30 to +105°C, allowing the fiber optic unit to operate at temperatures up to +105°C.
Q4: What are the thread sizes of FTH7BC?
A: FTH7BC features an M4 × P0.7 and M2.6 × P0.45 stepped threaded tip for equipment mounting.
Q5: What is the maximum detecting distance of FTH7BC?
A: With the F85RN fiber amplifier in long-distance mode, the detecting distance is 1,000 mm. Distances vary with other amplifiers.
Q6: What is the detecting distance of FTH7BC with F80R?
A: With the F80R amplifier, the detecting distance is 830 mm in long-distance mode and 460 mm in high-speed mode.
Q7: How long is the FTH7BC fiber, and can it be cut?
A: FTH7BC includes a 2 m free-cutting fiber that can be trimmed to suit equipment cable routing requirements.
Q8: What are the fiber materials and allowable bending radius of FTH7BC?
A: The fiber has a heat-resistant polyethylene covering and a plastic core. The cable diameter is φ2.2 mm, the core diameter is φ1.0 mm, and the allowable bending radius is R30.
Q9: Which fiber amplifiers are compatible with FTH7BC?
A: FTH7BC supports F2R, F70, F80R, and F85RN fiber amplifiers. Detecting distances vary depending on the amplifier and operating mode.
Q10: What should be considered when installing FTH7BC?
A: Verify the M4/M2.6 mounting dimensions, keep the thread tightening torque at or below 0.8 N·m, and maintain a fiber bending radius of at least R30.
