Pico-Lock Connectors

Molex Pico-Lock SMT Wire-to-Board Connectors offer a unique side positive-lock design and high current handling capacity for consumer applications. Available in 1mm, 1.5mm, 2mm, and 3mm pitch versions, the Pico-Lock wire-to-board system offers an ideal combination of low profile, high current, and durable locking for any application requiring space savings and secure mating retention. The side positive locks provide a high signal-line current capability of 10A. This design allows the Molex Pico-Lock connectors to achieve ultra-low profile, robust connections in applications such as LCD TVs, smart meters, and servers. A guide rib on the housing provides polarization and mating guidance for secure connections. Other features include friction locks for additional mating assurance and visual mating confirmation, as well as a wide solder tab that wraps up into the header and around the housing for additional PCB retention and mechanical system assurance.
