DIN Cables
There are many different versions of DIN Connectors. The name of each type comes from the number of pins the connector has (3-pin DIN, 4-pin DIN, etc.) Some of these pin numbers come in different configurations, with the pins arranged differently from one configuration to the next.
DIN cable connector 3-pin, 4-pin, 5-pin, 6-pin, 7-pin, 8-pin degree 180, 216, 240, 262, 270
