    When the switch is activated, little or no light is coupled back to the receiver. The MICRONOR Fiber Optic switches are immune to EMI/RFI and can be deployed at great distances from the electrical controller. Applications include: •...

    This universal PCB may be used in conjunction with many of the MICRONOR signaling devices. Figure 1. MR380 Fiber Optic Signaling Devices The MR380-0-UNI is intended for OEM applications where the PCB can be mounted into a suitable enclosure and where it is sufficiently protected from the environment such as water and dust or similar influences.

  • Page 6: Figure 2. Block Diagram For A Mr380-0 Controller System

    MR380-0-UNI Instruction Manual example, transmitting from OM1 fiber (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 MR380-0 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 7 MR380-0-UNI Instruction Manual which provides a known failure state. The controller then interprets events such as broken fiber, poor connection, high loss or a depressed switch as a failure or ‘EMERGENCY ON’. The photodetector outputs a logic signal to the remaining logic circuitry which then interprets high or low levels for the +5V digital and Open-Collector outputs.

  • Page 8: Initial Preparation

    The PCB is an electronic Assembly and susceptible to ESD. Please use appropriate grounding and caution when handling the PCB. In the event of a damaged product, write or call your nearest MICRONOR AG sales office. Please retain the shipping container in case re-shipment is required for any reason.

  • Page 9: Installation And Operation

    Be sure to use proper fiber optic cleaming tools and procedures such as the MICRONOR MR321C Cleaning Kit. Improper tools and/or processes may damage or contaminate the optical interface. Mounting the MR380-0 Controller PCB The controller PCB should be mounted on 4 standoffs.

    MR380-0-UNI Instruction Manual Optical Connections to the MR380-0 Controller A duplex fiber optic cable is used to interconnect the sensor and controller. The sensor incorporates a 1.5m optical pigtail (or as specified by customer). If a longer connection to the controller is required, then a fiber optic extension cable may be used.
