Proximity switches to achieve limit control
Inductive NPN Proximity Switches are easy to use as limit switch for hobby CNC machines. In this video I explain how I use them and how to select a pull down resistor that fits a digital input switching between zero and ca. 5V.
If you have a limited number of inputs you may want to use two switches in parallel e.g. for front and back on the same axis. In this case you must use a resistor of approximately half.
In the video I try to find resistors resulting in an output of ca 5V. The following was found: Single Sw 12V 10k; 24V 3.3k; 36V 2.2k. Two Sw in parallel: 12V 4.7k; 24V 1.5k and 36V 1k
Most Makers need to be able to Solder Wires to Wires or Wires to Connectors when Building Machines like CNC or 3D Printers. In this Video I show how I'm doing this and the Tolls I use. Some practice is needed to get a good result.
In this "Compare the Parts" video from Radwell TV, learn about basic operational differences between limit switch and proximity sensor, as outlined by host, Mike LaGambina.
