Hi, What are you trying to sense? and is this purely a distance measurment? Does the object have different colours, levels of reflectiveness and what is the environment. And why are you wanting a sensor with communications output and not Analogue? I know a lot of questions but I believe need to understand the application better to be able to help.

° Hi Adrian, thanks for your reply, i trying to sense how many lux of light, sensor can adjust to 10 meters and max. 25 meters from object. object have different colour with many level of light, machine place indoor, 20 - 36 °C i think serial data is a ready to use no need to convert more, and i never use analog input with PLC before, but if analogue input is better for 25 meters long distance i will trying, cause i have omron CP1W-AD041 Thans and Regards iyad
