Specification notes

Detecting distance and amplifier selection: The maximum detecting distances are 890 mm for FT19YBC and 2,700 mm for FT5YBC. Actual detecting distances depend on the selected fiber amplifier and operating mode.
Tip dimensions and cable routing: FT19YBC uses an M3 short-head tip with a Φ1.0 mm fiber cable, while FT5YBC features an M4 threaded tip with a Φ2.2 mm cable. Both have an allowable bending radius of R1 mm and a maximum thread tightening torque of 0.8 N·m.
Detectable object size: The standard detectable object diameter is Φ0.5 mm for FT19YBC and Φ1.0 mm for FT5YBC. Both specify a minimum detectable object diameter of Φ0.015 mm, excluding the F71R and F2R amplifiers.

FAQ

Q1: What are TAKEX FT19YBC and FT5YBC?
A: Both are R1 flexible threaded through-beam fiber optic units that detect objects by sensing changes in light between a transmitter and receiver.

Q2: What are the main differences between FT19YBC and FT5YBC?
A: FT19YBC features an M3 short-head tip and a φ1.0 mm fiber cable, while FT5YBC uses an M4 threaded tip and a φ2.2 mm cable. The models also differ in detecting distance.

Q3: What is the allowable bending radius of FT19YBC and FT5YBC?
A: Both models have an allowable bending radius of R1 mm, making them suitable for applications requiring curved cable routing.

Q4: Which model is more suitable for equipment with limited installation space?
A: FT19YBC features an M3 short-head tip and a thinner φ1.0 mm fiber cable, making it suitable when compact tip dimensions and cable routing space are priorities.

Q5: Which model is suitable for longer-distance object detection?
A: FT5YBC offers longer detecting distances. With the F85RN amplifier in long-distance mode, FT5YBC reaches 1,220 mm compared with 480 mm for FT19YBC.

Q6: Can the FT19YBC and FT5YBC fibers be cut to length?
A: Yes. Both models include 2 m free-cutting fibers that can be trimmed to meet equipment installation requirements.

Q7: Which fiber amplifiers are compatible with FT19YBC and FT5YBC?
A: Both models are compatible with F2R, F70, F80R, and F85RN fiber amplifiers. Detecting distances vary depending on the amplifier and operating mode.

Q8: What is the operating temperature range of FT19YBC and FT5YBC?
A: Both models operate within an ambient temperature range of −30 to +70°C and are classified as ordinary-temperature fiber optic units.

Q9: What is the smallest detectable object for FT19YBC and FT5YBC?
A: The standard detectable object diameter is φ0.5 mm for FT19YBC and φ1.0 mm for FT5YBC. Both specify a minimum detectable object diameter of φ0.015 mm, excluding F71R and F2R amplifiers.

Q10: What should be considered when installing FT19YBC and FT5YBC?
A: Select the correct mounting position for the M3 or M4 threaded tip, keep the tightening torque at or below 0.8 N·m, and observe the R1 mm allowable bending radius.
