Week #9 (3/20-24): Sensor Wiring & Testing
Posted: Tue Mar 21, 2023 12:12 pm
This week your lab exercise will be to test a good number and variety of proximity sensors we have in the department. The goal is to remove from circulation any sensors which do not work, and categorize those that due by their type.
Here's a short YouTube video on How to Check a Three-Wire Proximity Sensor (1:49).
And here's a longer video which does the same with additional information about NPN and PNP type outputs. How to Test a Proximity Sensor (6:27).
These links were included in the Week #5 lecture of EET-265 and repeated here for convenience. Some supplemental information from Wisc-Online about:
Two Wire Sensors
Three Wire Sensors
Four Wire Sensors
An explanation of the Difference between NPN and PNP Devices. Also info on sinking and sourcing.
