T he ends of glass fiber optic assemblies are optically ground and polished. Care taken in this
manufacturing process accounts for the light coupling efficiency of the fiber optic assembly. As a
result, glass fiber assemblies cannot be shortened, spliced or otherwise modified.
U se caution when applying fiber optics in hazardous locations. Although fiber optic assemblies are
by themselves, intrinsically safe, the sensor and associated electronics must be LOCATED IN A
SAFE ENVIRONMENT. Alternatively, fiber optics may be used with sensor model SMI912FQD
(page 34). This sensor is approved for use inside hazardous areas when used with an appropriate
intrinsic barrier. Also, see NAMUR sensor models Q45AD9F (page 156) and MIAD9F (page 90).
Fiber optics do not necessarily provide a hermetic seal between a hazardous environment and the
safe environment.

Combination of optical glass fiber, stainless steel or PVC, brass, molded thermoplastics, and optical-grade
epoxy. Optical fiber is F2 core, EN1 clad, approx. 50 µm diameter per strand. Flexible steel interlock
sheathing is 302 stainless.
Refer to the specific fiber optic to be used.
Inside bend radius must be 12 mm or greater for PVC covered fiber optic assemblies, and 25 mm or
greater for stainless steel armored cable covered fibers.
Standard length for assemblies is 915 mm; see dimension diagrams.
Most models are available from the factory with shorter or longer cable lengths, up to 18 m max.
Overall assembly length: ±12 mm per 300 mm of length
Shrink junction dimensions: ±12 mm
All dimensions are in millimeters: x = ±2.5 mm, x.x = ±0.25 mm and x.xx = ±0.12 mm, unless specified.
