Liquid detection optical fibers from Panasonic are specialized sensing elements designed to identify the presence of conductive or non-conductive liquids in industrial environments. These fibers operate on the principle of light transmission interruption when the fiber optic core is exposed to liquid, triggering a signal change in the connected amplifier. Key technical parameters include fiber core diameter (typically 0.5 mm to 1.0 mm), operating temperature range (-40°C to +70°C), and minimum bending radius (R10 mm or R25 mm depending on model). The fibers are available in straight-tip or right-angle configurations, with fluororesin or PVC sheathing for chemical resistance. They are compatible with Panasonic FX-300 series or equivalent fiber optic amplifiers, requiring no electrical contact with the liquid, making them intrinsically safe for hazardous area monitoring.

These optical fibers are deployed in leak detection systems for data centers, chemical storage tanks, hydraulic oil reservoirs, and cooling water circuits in power generation plants. They are also used in semiconductor wet benches, food processing washdown areas, and pharmaceutical cleanrooms where early liquid detection prevents costly equipment damage or product contamination. The non-metallic construction allows installation in corrosive environments or near high-voltage equipment without risk of short circuits. Typical mounting involves adhesive clips or bracket fixtures along pipes, sump edges, or under raised floors.

Subcategories within this range include FD-L20 series (standard sensitivity, 2 m length), FD-L40 series (high sensitivity for oil detection, 4 m length), and FD-L60 series (extended range up to 6 m for large-area monitoring). The article code structure follows the pattern FD-L[length in decimeters][tip type], where 'S' denotes straight tip and 'R' denotes right-angle tip. For example, FD-L20S indicates a 2-meter straight-tip fiber, while FD-L40R is a 4-meter right-angle fiber. These are complete sensing fibers, not accessories like amplifiers or mounting brackets, which are listed separately.

Partnering with Electric Automation Network ensures access to genuine Panasonic liquid detection fibers with full technical documentation including installation manuals and sensitivity curves. Our engineering team provides application-specific recommendations for fiber length and tip selection based on your tank geometry or pipe layout. We offer express worldwide shipping from stock, with real-time pricing and volume discounts up to 65% off list price. Each order includes a certificate of conformity and traceability to original manufacturing batches.
