External Input Unit for Digital Sensor FX-CH2

CE Approved

Features

Support for stable sensing and smooth setup changes!

Teaching and data bank switching for up to a maximum of 16 digital fiber sensors (FX-301 and FX-305) can be carried out all at once using an external device such as a PLC, touch screen or switch.

Stable sensing applications using external teaching

Sensing glass substrate (stable sensing of minute differences)

When sensing transparent objects and extremely small objects, variations in the incident light intensity caused by external factors such as slippage of the beam axis due to vibration can result in incorrect operation.
In such cases, periodically setting limit teaching '-' can be used to ensure more stable sensing.

Sensing object in poor environments (remedying incident light intensity damping due to dust)

If dust or other particles cover the fibers, it can reduce the incident light intensity. In such cases, periodically setting limit teaching '-' can be used to ensure more stable sensing.

Applications involving smooth setup operations

Digital fiber settings can be changed using input from a touch screen or switch, so that production line setup changes can be carried out more easily.

・External teaching
Full-auto teaching is recommended for teaching when the sensing object is changed without stopping the line.

・Data bank switching
Settings such as output operations (L-ON / D-ON) and timer operations can be recorded in the digital fiber sensor's data bank and switching can be carried out externally.
* Up to 3 files can be stored.

<Teaching input>
