Description
XM-LHGG is a fixed female receptacle designed for nut mounting on equipment panels. Its straight configuration provides a compact and secure panel-mounted connection for industrial electronic equipment.
The connector is designed as a watertight or vacuum-sealed type, making it suitable for applications where reliable sealing is required. The front mounting structure allows the receptacle to be securely installed through a panel using a threaded nut.
XM-LHGG features a Push-Pull self-locking mechanism and a standard G alignment key for reliable and correctly oriented mating. It is available in 0K, 1K, 2K and 3K sizes.
As part of the K Series, the connector combines a rugged metal housing with IP66/IP68 protection, 360° EMC shielding, high packing density and 2–64 contact configurations for demanding industrial applications.

These receptacles and bulkhead types enable the equipment in which they are used to achieve IP68 protection level. They are fully compatible with plugs of the same series, and are therefore widely used in portable wireless devices, military, laboratory equipment, and aerospace applications. The sealing material for these types is epoxy resin.
