Preventing Multiple Sensor Outputs from Becoming Connected


Forcing NPN or PNP operation

The Challenge

Many of the EMX sensor products such as the UVX, CNTX and CMYX feature automatic detection and configuration of the discrete output mode for PNP or NPN operation. This feature prevents connecting the outputs from multiple sensors in parallel. The following diagrams illustrate how to connect the EMX sensors in parallel to any other sensor.
