21、 MT connector family 1 Scope This part of IEC 61754 defines the standard interface dimensions for the type MT family of connectors. 2 Description The parent connector for type MT connector family is a multiway plug connector characterized by a rectangular ferrule, typically 2,5 mm by 6,4 mm. The con

22、nector is aligned using two alignment pins and is normally secured by the use of a latching spring. Each connector interface may be configured in a number of ways as shown in Figure 1. In the parent version, the two alignment pins are free to move within the plug bodies, and hence when unplugged may

23、 be located in either plug. The connector may also be configured with one pin fixed in each half (a hermaphroditic variant), or with both pins fixed in one plug (a plug and socket variant). Figure 1 shows which variants are intermateable as follows: a) parent plug to parent plug using two free pins;

24、 b) single pin plug to parent plug using one extra free pin; c) two pin plug to parent plug; d) single pin plug to single pin plug. NOTE The two pin plug will not intermate with the single pin plug. Different connector interfaces will intermate and will correctly align the lower defined number of op

25、tical datum targets. 3 Interfaces This standard contains the following standard interface: Interface 5-1 MT interface dimensions Licensed Copy: Wang Bin, na, Fri May 12 02:24:27 BST 2006, Uncontrolled Copy, (c) BSI 5 EN 61754-5:2005 connecteur deux broches Parent plug Pin Parent plug Plug with two p
