Banner Engineering DBT23S Fiber Optic Sensor

Banner Engineering's DBT23S is a high-temperature, double bifurcated fiber optic assembly designed to route light to two sensing locations from a single Banner fiber-optic sensor head. This glass-fiber bundle measures 36 inches in length with a 0.125 inch (3.2 mm) diameter, and uses stainless steel hardware for durability in demanding industrial environments. Part of Banner’s High Temperature Fiber Optics family, the DBT23S is engineered for applications where reach and split-fiber configuration are needed in tight spaces or near heat sources, enabling dual sensing paths without running separate cables. The assembly integrates with Banner’s fiber optic sensor ecosystem, pairing with compatible sensor heads and amplifiers to detect changes in light transmission at the fiber tips. Designed for manufacturing and processing environments, it supports remote sensing in areas that would be inaccessible to conventional photoelectric sensors, while maintaining performance in elevated temperatures. In practice, users leverage the DBT23S to extend sensing reach, monitor two separate points along a single installation, or create flexible layouts where direct access to a sensor head is constrained.
