Spotlighted at the Harwin Stand 313 in Hall C will be new connectors that address industrial, avionics, UAV, auto-sport, marine, and robotics applications, as well as a reverse-fix option and cable assemblies for their popular Gecko series of 1.25mm pitch connectors.
Premiering at the show will be the recently introduced circular sensor Vivern connectors designed for use with 24AWG and 26AWG network cabling. Each have an IP67 compliant sealed housing to combat liquid ingress. With a current rating of 2A per contact, the members of the Vivern family come in a 10-contact 1.45mm pitch format and have an insulation resistance of over 1GΩ. They can be supplied in both cable-to-cable and cable-to-board configurations.
The lightweight but rugged construction of these compact (10.6mm external diameter), polarized components means that they are well suited to implementation in high-performance automotive applications (such as motor racing), as well as various other potentially high impact applications where there are also weight and space constraints to consider (including robotics and avionics). The breakaway collar incorporated into the bayonet locking mechanism can be sacrificed in order to protect against wired connector damage caused by adverse loads and external impacts. The contacts are made from a copper alloy with gold plate finish to augment their durability.
Capable of withstanding a 10G vibrational force for a period of 6 hours, the components in Harwin’s new M225 connector series are intended for industrial deployment.
These compact, high-performance cable-to-board units feature a robust construction for prolonged operational lifespan, thanks to their glass-reinforced polyphenylene sulfide (PPS) enclosures, with a 100MΩ minimum insulation resistance ensuring continued signal integrity. They have a double row contact arrangement with a 2 mm pitch – enabling mating of their through-board PCB male connectors to the corresponding female crimp connectors – with an array of different wire sizes (from 22 to 28 AWG) being accommodated. Each tin-plated copper alloy male contact has a current rating of 3.3 A (3.0 A when all contacts are electrically loaded simultaneously) and a maximum contact resistance of 25 mΩ. When mated, the single-piece female contacts each have three surfaces touching the corresponding male pin. This means that reliable interconnection is maintained, even when placed in the most uncompromising of application settings and under extremely challenging working conditions.
Gecko Screw-Lox connectors now with reverse fix option
Harwin has extended the scope of its award-winning Gecko Screw-Lok (Gecko-SL) 1.25-mm pitch connector solutions — which are mainly targeted at avionics, space, military and autosport deployment.
Typically on standard jackscrew and screw-lok systems, the female connector has the floating jackscrew that you use to fix the two mating halves together, and the male has the board mounting stud. This makes it easiest to design the male to the PCB, and female to a cable. However, for customers who need the female on the PCB or panel, a reverse fix screw-lok design is required.
To present engineers with greater design flexibility, and ensure that mating procedures are made as straightforward as possible, a reverse fix orientation has now been made available for the robust and reliable stainless steel screw-loks incorporated into each Gecko-SL. The male connectors serve as the floating fixings and screw into the female connectors — as opposed to conventional Gecko-SL systems, where it is the female connectors that have the floating fixings. In addition, designers can now use both a female and a male on the PCB, and opposite on two different cables, to avoid mating the wrong cable to the wrong PCB connector.
