Miniature Safety Limit Switch D4N 5
Note: It is recommended that M20 be used for Switches to be exported to Europe and 1/2-14NPT be used for Switches to be exported to North
American countries.
General-purpose Switches with Two Contacts
Note: 1. It is recommended that M20 be used for Switches to be exported to Europe and 1/2-14NPT be used for Switches to be exported to North
American countries.
2. Mechanically speaking, these models are basic limit switches.
