MR386 Microswitch with MR380-1-3 Controller The MR386 Fiber Optic Microswitch paired with the MR380-1-3 Controller provides a new, innovative signaling detection that can be deployed in difficult, hazardous environments and over very long distances. The Microswitch employs a photo interrupt scheme operating over a duplex 62.5/125μm fiber optic link that allows for reliable signal detection.

  • Page 7: Fields Of Application

    MR380-1-3 Instruction Manual There are two switch materials. The completely non–metallic version is designed to operate within an MRI environment where high magnetic fields would interfere with any electronic switch. The switch may be safely used within the MRI bore because it is immune to the magnetic field as well as invisible to the imaging process.

    (62.5µm core) to OM2 fiber (50µm core) produces a loss of approximately 1.2dB, which is not a problem in most situations. In the MR380-1-3 controller, the transmit fiber is OS1 9/125µm single mode fiber. Since the core of the fiber is smaller than any other standard fiber, no losses are produced at this connection, no matter which standard fiber the rest of the system uses.

  • Page 20: Functional Block Diagram

    Controller Figure 10. Block Diagram for a MR380-1-3 Controller System The light source power is held constant under normal operating conditions allowing for a known system loss budget when designing a system. Additionally, the optics within the switch are designed to couple maximum light back into the receive fiber enabling the ability to create long distance systems and chain multiple switches.

  • Page 21: Application Notes

    8. Application Notes Determining System Loss Budget when Chaining Multiple Switches The MR380-1-3 controllers have the capacity to chain multiple switches in series, permitted that the additional losses fall within the optical system loss budget. Figure 11 illustrates a system using three MR387 switches in series.
