How to connect the end plug of a fiber optic sensor amplifier

To connect the end plug of a fiber optic sensor amplifier, insert the fiber cables into the correct inlets, secure them with the fiber lock lever, and install optional end plates if the amplifier is part of a cascade.

Step-by-Step Instructions

1. Power Off the Amplifier Ensure the amplifier is turned off before connecting or disconnecting any fibers or plugs to prevent damage or unstable output .
2. Prepare the Amplifier and Fibers
   • Mount the amplifier on a DIN rail if required.
   • Fit any attachments to the fiber cables before inserting them into the amplifier .
3. Insert Fiber Cables
   • Identify the beam-emitting inlet (usually labeled “P”) for the single-core fiber and the beam-receiving inlet for the multi-core fiber.
   • Insert the fibers slowly until they stop. Avoid bending flexible fibers inside the amplifier, as this can reduce sensing accuracy .
   • Snap the fiber lock lever down to secure the fibers, then return it to its original position until it stops .
4. Connect the End Plug (Quick-Connection Cable)
   • Use the optional quick-connection cable supplied for the amplifier type.
   • Insert the connector into the amplifier until a click is felt. Do not use cables with broken projections, and avoid pulling the cable by the wire to prevent damage .
   • For cascading multiple amplifiers, use the main cable for the first amplifier and sub cables for subsequent amplifiers .
5. Install End Plates (Optional for Cascade)
   • If the amplifier is part of a cascade, mount MS-DIN-E end plates at both ends to hold the amplifiers together.
   • Tighten the screws to secure the end plates. This helps reduce noise and stabilizes the connection .
   • To remove, loosen the screws and slide the amplifiers away one by one.
6. Final Checks
   • Verify that fibers are fully inserted and the lock lever is properly engaged.
   • Ensure the power supply voltage is within the rated range and that the amplifier is grounded properly .
   • Turn on the amplifier and perform any full-auto teaching or threshold adjustments as needed for your sensing application . By following these steps, the end plug and fiber connections will be secure, ensuring accurate sensing and reliable operation of the fiber optic amplifier.
