SPECIFICATIONS
Reliability and ease of use make the PRX102
Series inductive proximity sensors the
number one choice for numerous automation
and robotics applications. These switches
can detect any metal, and they are highly
insensitive to contaminants such as dirt,
dust, humidity, and oil. An LED indicator
alerts the user to whether the sensor is
working. The open collector can be either
NPN or PNP.
