DESCRIPTION OF CONNECTOR The G125 series of connectors (branded “Gecko”) comprises of: barrel crimp contacts and crimp housings available in Male and Female genders; Vertical and Horizontal PC-Tail Connectors and Vertical Surface Mount Connectors; all on a 1.25mm pitch. Connectors are fully shrouded, unsealed connectors for interconnecting cable-to-cable, cable-to-board and board-to-board applications. The Gecko 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 cable assemblies are supplied back-potted for customer convenience, and individually crimped contacts are also available. There are three variants of the range, the ranges are not intermateable: • Gecko-SL – Screw-Lok version. Female connectors have floating screws for secure, robust interconnection to the male counterpart. Male Screw-Loks can also have board-mount studs for secure PCB connection. • Gecko with Latches (original design). Male variants 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. • Gecko-MT. Connectors are equipped with both signal and power contacts and are available in crimped or through-board configurations. Screw-Lok technology is used to secure the connectors, and board-mount studs for PCB fastening are available. 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 Gecko-SL and latched ranges cover 06, 10, 12, 16, 20, 26, 34 and 50 total number of contacts in a dual row configuration. Connector housings are polarised to prevent mis-matching and have contact position one indicated on the outside of the housings. Metal backshells are available for sizes 06, 10, 12 and 16 cable variants in the Gecko-SL range, to provide mechanical, RF and EMC protection. Gecko-MT connectors are available in ’01-08-01’ and ’02-08-02’ configurations, with 2 power contacts and 8 signal contacts or 4 power contacts and 8 signal contacts respectively. 2. RATINGS 2.1.
