Specification notes
Q1: What is TAKEX FT91YBC?
A: FT91YBC is an R4 flexible through-beam fiber optic unit with a φ1.5 mm straight cylindrical tip for non-contact object detection in automated equipment.
Q2: What detection method does FT91YBC use?
A: FT91YBC uses through-beam detection by sensing changes in light between the transmitter and receiver.
Q3: What is the tip size of FT91YBC?
A: FT91YBC features a φ1.5 mm straight cylindrical tip suitable for installations requiring a compact sensing head.
Q4: What is the allowable bending radius of FT91YBC?
A: The allowable bending radius is R4 (4 mm), supporting curved fiber cable routing inside equipment.
Q5: What is the detecting distance of FT91YBC?
A: Detecting distance varies by fiber amplifier. With F85RN in long-distance mode, the detecting distance is 610 mm. With F80R in long-distance mode, it is 180 mm.
Q6: What is the detecting distance of FT91YBC with F85RN?
A: With the F85RN fiber amplifier, the detecting distance is 610 mm in long-distance mode and 170 mm in high-speed mode.
Q7: How long is the FT91YBC fiber, and can it be cut?
A: FT91YBC features a 2 m free-cutting fiber with a φ1.0 mm cable diameter, allowing the length to be adjusted to equipment requirements.
Q8: Which fiber amplifiers are compatible with FT91YBC?
A: The specified amplifiers are F2R, F70, F80R, and F85RN. Detecting distances depend on the selected amplifier and operating mode.
Q9: What is the operating temperature range of FT91YBC?
A: FT91YBC operates within an ambient temperature range of −30 to +70°C and is classified as an ordinary-temperature fiber optic unit.
Q10: What is the smallest object FT91YBC can detect?
A: The standard detectable object diameter is φ0.5 mm, and the minimum detectable object diameter is φ0.015 mm, excluding F71R and F2R amplifiers.
