CONNECTOR
APPLICATION.
1.0 DESCRIPTION OF CONNECTOR AND INTENDED APPLICATION.
The G125 series of connectors is comprised of barrel crimp contacts and crimp housings; available in Male and Female
applications as well as Vertical PC-Tail and Surface Mount Connectors on a 1.25mm pitch.
The G125 Crimp variants are fully shrouded, unsealed connectors with replaceable contacts. They are designed for
interconnecting cable-to-cable and cable-to-board. The housings have a low profile potting wall to allow back potting for
additional strain relief and improved sealing where required. All pre-made cables are supplied back-potted for customer
convenience. Male variants can be equipped with locking latches for secure interconnection with easy to release features.
The G125 Vertical variants are fully shrouded, unsealed connectors for interconnecting cable-to-board and board-to-board. The
Male connectors can be equipped with locking latches for secure interconnection with easy to release features. Latches can
be specified with through board locking features or surface mount pads for additional security.
All contacts are gold plated all over for high performance and long service life, the contact plating is hard acid gold of 98%
purity.
The G125 series range covers 06, 10, 12, 16, 20, 26, 34 & 50 total number of contacts currently in a dual row configuration,
suitable for various cable-to-cable, cable-to-board and board-to-board applications. Connector housings are polarised to
prevent mis-matching and have contact position one indicated on the outside of the housings.
