1. K series connector brief introduction:
K series connectors offers a solution for outdoor applications.Watertight self-latching multipole connectors with alignment key, The integral sealing within both plug and socket offers a IP68 watertight connection when mated. The push pull latching mechanism provides a secure connection whilst the density of the contacts provide considerable panel space savings. Multi key options prevent cross mating of similar connectors within a panel. Contact types include LV (low voltage), The chrome plated version is resistant to more than 1000hours of salt spray corrosion test. The ruggedised design combined with precision manufacturing offers excellent durability, reliability and quality. Making it an ideal choice for Medical, Test & Measurement, Research, Communications, Broadcast Connector, Machines, Defense, Robotic, Aerospace, public sector, Information Systems, Motorsport, Miscellaneous applications. These high quality Spring Technology connectors cable assembly can be provided. it can cross Lemo variations and sizes.
