Purchase now: Wenglor LW86 Fiber Optic Barrier
Purchase now: Atlantech Drives provides you the Wenglor LW86, a heavy-duty Glass Fiber Optic Cable designed for Through-Beam (One-Way) operation. This product is engineered for extreme environments where standard electronic sensors cannot survive. By separating the electronics (the amplifier) from the sensing point using glass fiber bundles, the LW86 allows detection in areas with ambient temperatures up to 250°C (or higher depending on the specific sub-version) and high mechanical stress.
Technical Specifications and Stainless Steel Sheath
The LW86 features a flexible Stainless Steel / Metal Spiral sheathing that protects the glass fibers from crushing, hot chips, and sparks. As a through-beam system, it consists of two branches (Emitter and Receiver) that must be aligned. When an object breaks the light beam between the two heads, the amplifier switches. Glass fibers transmit light in the infrared or red spectrum efficiently and do not degrade under heat like plastic fibers (POF) do.

Expert Installation Advice: Bending Radius
Glass breaks. Expert Tip: While the stainless steel jacket looks rugged, the glass strands inside are brittle. Never force the cable into a sharp 90-degree bend tighter than the specified radius (usually R ≥ 60mm). If you hear a «crunching» sound during installation, you have broken the fibers. Also, ensure the fiber ends (ferrules) are fully seated in the amplifier and locked down to prevent light loss.
Frequently Asked Questions (FAQs)
Q: Do I need two of these?
A: A through-beam fiber usually comes as a pair or a bifurcated assembly. The LW86 typically refers to the cable assembly. You need one compatible Wenglor Fiber Optic Amplifier (e.g., UF series) to power it.
Q: Can it detect clear glass?
A: Through-beam glass fibers are extremely powerful (high excess gain). They will punch through clear glass. To detect clear glass, you generally need to turn the potentiometer on the amplifier down significantly or use a Reflex fiber instead.
