【Overview】
MX23A connector is a compact, low-profile, waterproof connector that can be used
in a wide range of waterproof equipment including automobiles, motorcycles and other
outdoor equipment .
This connector has high environmental capability with a waterproof structure consisting
of a seal ring in its mating area and a grommet in its wire insertion area for full protection
against water. Reverse type pin connector (with pins facing up) is also available in
consideration of mounting flexibility.
【Applicable Markets】
Waterproof equipment for automobiles, motorcycles, and general waterproof equipment
【Features】
■Low profile with board mounting height of 18.3mm and socket connector height of
22.2mm max. ( 2-row type :12 to 34 pos.)
■Two leaf springs with high reliability is adopted for socket contact and large chamfer is
prepared in the front-edge to prevent damaging the grommet .
■Incomplete insertion of socket contact into its housing can be detected with the front
cap mounting process.
■Fully waterproof grommet is used for crimped socket contact insertion area to reduce
size.
■Water ingress protection is achieved in connector’s mating area with a seal ring . It is
fully protected from handling by the insulator .
■Reverse type pin connector (with pins facing up) is also available. (18, 26, 34 pos.)
