Miniature spring probe contact connectors
18 July 2008
High-reliability connector maker, Harwin has just added miniature P20 spring probe contact connectors to its product portfolio. P20 spring probe contact connectors maintain a positive force against a mating surface. With very low mating forces connection is rapid, effortless and user-friendly, and significant mating misalignments can be tolerated.
Available in two, three, four and five way configurations, P20 connectors can handle up to 1A at a voltage of 12Vdc. Contact resistance is 50mΩ max; insulation resistance is 100 MΩ min. Operating temperature range is -40ºC to +85ºC and the connectors are guaranteed for 10,000 operations. Two way devices measure 3.9mm in height, while three and four-way styles are 3.4mm high and five way units stand 4.5mm tall.
Paul Gillam, Harwin’s commercial product manager, commented: “We are well-established as suppliers of the Hot Shoe range of spring-loaded, positive contact connectors, but these devices are much smaller. The new P20 spring contact connectors especially suit price-sensitive, high volume consumer applications, such as portable equipment where separate battery modules are used, and also data transfer docking stations.”
