Connectors did not work. They were very short and flimsy, and also didn't use enough length of wire inside to conduct DC current without causing heat problems. Had to replace with a higher quality butt connector to fix overheating issues.
Pros
Purpose and Use: These ferrules can be used to connect the machine to a PLC, HMI and power supply, speakers or other electronic devices. They are easy to use and excellent for electrical conduction and tin electroplating processes.
