| Product | IO-Link communication unit for safety light curtain SF4D series |
| Material | Main unit case: PA66 (with glass)Base plate: SPCC + PlatingProduct model nameplate: PolyesterExternal connection connector: Brass + Plating |
| Functions | • IO-Link communication function• Safety light curtain setting data copy function (Note)Note :• The internal memory (nonvolatile) of this product has a service life. Settings cannot be configured more than 100,000 times.• This product cannot be used to directly enter settings from the IO-Link master unit to a safety light curtain using IO-Link communication.• The safety light curtain setting data copy function is designed only for use in maintenance / replace of safety light curtains.Use the copy function only for loading the setting data of the previous safety light curtain to a new unit. Loading the data to a device other than a newly installed safety light curtain may result in improper device operation.• This function cannot be used unless the product is connected with the IO-Link master unit and IO-Link communication is used. |
