The fiber amplifier D4RF-TD can be used to detect the presence of containers filled with powdered glass.
When powders are being mixed in next processes, airborne powder can adhere to the optical surface of the sensor, decreasing the received light amount and resulting in malfunctions.
Ultra-high-speed digital fiber amplifiers D4RF-TD, however, equipped with two outputs, meaning output 2 can be used to detect decreases in the received light amount. This also allows for advance determination of when maintenance will be required, helping to reduce downtime.

Limited reflective type fiber cable NF-DC06 can detect each glass plate in the rack.
It detects stably even if the glass plate warps because of its special structure.
Controlling each fiber amplifier can be done through CC-Link utilizing communication unit UC1-CL1 connected to Mitsubishi MELSEC-Q/L series efficiently as well.
