DESCRIPTION OF CONNECTOR Gecko connectors are 1.25mm pitch high-reliability rectangular connectors, with part numbers starting G125. There are three variants of the range; the variants are not intermateable:  Gecko-SL Screw-Lok: one connector has floating screws for secure, robust interconnection to the counterpart. Screw-Loks can also have board or panel mount studs for secure PCB or enclosure retention.  Gecko-MT Mixed Technology: connectors are equipped with both signal and power contacts and are available in cable or throughboard configurations. The same Screw-Lok fixing variations as Gecko-SL are available.  Gecko Latch (original design) Male connectors can be equipped with easy to release locking latches for secure interconnection to the female. Latches can be specified with through board locking features or surface mount pads for additional security. The ranges generally comprise of cable barrel crimp contacts and housings available in Male and Female genders; Vertical and Horizontal Throughboard PC Tail Connectors and Vertical Surface Mount Connectors. Connectors are fully shrouded, unsealed connectors for interconnecting cable-to-cable, cable-to-board, and board-to-board applications. The Gecko cable connectors are supplied as connector housings and separately ordered replaceable contacts. They are designed for interconnecting cable-to-cable and cable-to-board. The housings have a low profile potting wall to allow backpotting for additional strain relief and improved sealing. All ready-made cable assemblies are supplied backpotted for customer convenience, and individually pre-cabled contacts are also available. All contacts are gold plated for high performance and long service life; the contact plating is hard acid gold of 98% purity. The Gecko-SL and Latch ranges cover various sizes from 6 to 50 total number of contacts in a dual row configuration. Connector housings are polarised to prevent mis-mating and have contact number one indicated on the outside of the housings. Metal backshells are available that are compatible with both Gecko-SL and Gecko-MT ranges, to provide mechanical, RF and EMC protection. Gecko-MT connectors are available in a variety of signal (double row) and power (single row) contact configurations – check the website for the latest contact variations available. 2. RATINGS 2.1.
