Product Introduction
Our Built-in Lens Tough Fiber Optic Sensor FT FD Series includes through-beam FT and coaxial reflective FD probes with integrated micro lenses. The SUS303 stainless steel probe comes in M3 thread and Φ1.5mm compact cylinder styles. The built-in lens & inner guide rod delivers clear narrow-angle spots to reduce light scattering. Paired with FX-500 amplifiers, it offers 10x longer detection range and avoids lens falling off during automation.

FAQ
Q: What amplifiers are compatible with FT and FD fiber probes?
A: This fiber series perfectly matches the FX-500 series fiber amplifiers, including FX-501STD and other FX-500 model variants.
Q: What is the advantage of built-in lens compared to ordinary fiber without lens?
A: Built-in lens reduces light diffusion with smaller opening angles, extends maximum detection distance to 10 times of regular fiber, and prevents lens falling into workpieces to avoid product contamination.
Q: Can the tough fiber wire withstand frequent bending on robotic arms?
A: Yes, the tough fiber supports 180° repeated bending with R10mm minimum bending radius, no cracking or signal attenuation under frequent movement.
