SMI Connector for Industrial Control / Medical Sensor Cable
SMI fiber optic connector for industrial control equipment and medical sensor signal connection cables. Compact POF connector for sensor data links.
The SMI connector is a compact plastic optical fiber connector used on industrial control equipment and medical sensor signal cables. It provides a small, light-weight optical link for sensor data and control signals where EMI immunity matters.
Product Overview
SMI is a small-form POF connector typically used in sensor and device internal optical links. Its compact body suits space-limited medical and industrial instrumentation.
Because it is plastic and light-weight, the SMI is a cost-effective choice for short sensor signal runs rather than long backbone links.
Key Features

FAQ
What is the difference between SMI and ST/SMA905? SMI is a smaller, light-weight plastic connector for short sensor/control links, while ST and SMA905 are larger rugged metal connectors for machine and industrial jumpers. Choose SMI for compact device ports and ST/SMA905 for rugged external cables.
Why Choose Us
We match the SMI termination to your actual port and fiber, and keep assembly records per order so replacement cables match.
