Signal form selection and failure protection of proximity switch
The company issued a letter "about the configuration regulation of inductive proximity switch". In the regulation, the factory configuration of RL / CL is required to adopt normally open no mode, and the factory configuration of WL and HL is required to adopt normally closed NC mode. Some people are not clear about the reason why this configuration is adopted, and occasionally there are some cases that do not conform to the regulation The relationship between the selection of switch signal form and failure protection is explained.
