BGS-HDL can be utilized for controlling start/stop of feeding of parts into parts feeder bowl.
Because BGS-HDL has 2 outputs and those threshold can be set individually, it can detect not only shortage of the parts but also over feeding.
You can reduce number of sensors from 2 to 1.

The fiber cable NF-DF08 is developped dedicated for detecting liquid level.
It can be used for automatic liquid level control system using multiple NF-DF08, fiber sensor amplifier D3RF and CC-Link unit UC1-CL11 mounting fiber cable at 4 levels and connecting UC1-CL11to control system through CC-Link communication protocol.

Accurate C-MOS laser BGS sensor BGS-HL can detect existence of very small and thin object like O ring because of its one of the features, digital subpixel process.

DSD-100 has coaxial structure in the sensor head which makes it possible detecting objects in narrow space.

BGS-Z10 can detect object with various colors and materials.

Laser sensor head DSTA-200 can detect the presence of washer.
It detects object in the laser beam 30mm width area.

Screen fiber cable NF-TS40 with 40mm width light screen makes it possible counting screws go through the area of 40mm width.

Fiber sensor amplifier D3RF and fiber cable NF-TR03 can detect fine gold wire on winding machine.
The core diameter of NF-TR03 is very fine φ0.25mm.
Stable detection of gold wire reeled at high speed is available.

Built-in amplifier laser sensor ZR-L1000N can detect the edge of paper accurately because of its small spot size, φ2.5mm Minimum.

Color mark sensor DM-18TN can detect marks on the edge face of ingot.
Teaching function is equipped in DM-18TN which can be set easily by pushing button when the beam spot is at the mark.
Also, color setting can be adjusted by checking digital displays on the back.

Coaxial diffuse reflective type fiber cable NF-DM02-G4 with spot size adjustable lens NF-DA06 attached can detect if there is thread or not.
