Frequently Asked Questions
When applying a background or foreground suppression sensor be sure to pay attention to the orientation
of the target object to the sensor face. See the picture below.
These are the 2 orientations Detecting an object moving in the above
recommneded for BGS direction may cause instability in certain
applications situations. Test before installing if you have
to mount in this orientation
IP69K is a rating of German standard DIN 40050-9 extending the IEC 60529 rating system for high-pressure, high-temperature wash down applications.
Response time of a sensor is the maximum amount of time it takes for the sensor to detect a target object and change the state of the output signal.
In order to calculate response time of a rotating target we have to convert rotational speed to linear speed.
One good question is to ask whether or not the common of the PLC is connected to + voltage or 0 voltage.
If the DC voltage PLC has a positive voltage common, an NPN output sensor is required. If the DC voltage PLC has a 0v common, a PNP output sensor is required.
If the DC voltage PLC has a positive voltage common, an NPN output sensor is required. If the DC voltage PLC has a 0v common, a PNP output sensor is required.
Four of the most common sensor outputs are NPN current sinking, PNP current sourcing, Two-wire DC/AC and Relay.
