Banner Engineering BT230SMSS Fiber Optic Sensor

Banner Engineering BT230SMSS Fiber Optic Sensor is a glass-fiber optic sensor in Banner’s BT23 family, engineered for diffuse-reflective sensing with a bifurcated glass fiber bundle and a right-angled sensing geometry. This high-temperature fiber-optic platform uses glass fibers to route the sensing path, allowing the sensing element to sit away from the target to handle harsh environments or confined spaces. In diffuse-mode operation, light emitted into the fiber reflects off the target and returns to the receiver for detection, enabling presence/absence sensing without exposing the electronics to the target area. The bifurcated bundle design concentrates illumination at the sensing tip while enabling efficient light collection, improving stability and repeatability in tight installations. The BT230SMSS designation identifies this specific glass-fiber optic sensor variant within Banner’s diffuse-mode, fiber-cused line, a solution commonly used where small form factor and fiber isolation are advantageous in industrial automation.
