Diversified technology company 3M now offers a 2mm by 2mm latch/eject header for wire-to-board connections. The compact header offers a durable, flexible solution for applications where circuit board space is a concern. The 3M 2mm latch/eject header provides a robust system solution when mated with 3M IDC 1522 series sockets and 3M 2mm moulded assemblies series.
The header is suitable for a variety of electronic applications, including blade servers, medical electronics, motor control boards, data collection devices and high performance audio components.
The latch/ejectors maintain a secure connection to the cable assembly during operation, yet allow for easy removal of the harness when needed. 3M uses roll pins to attach the latches instead of a snap-in system, designed to enable connectivity in high-vibration applications and during shipping. The latch incorporates a unique design that resists breakage when ejecting the mating assembly, increasing system reliability.
The 3M family of 2mm latch/eject headers features 13-pin count options from six to 50 positions, offering design flexibility across applications. The connector bodies feature a cut-out to accommodate mating connectors with centre bump polarisation and are made from PCT resins, allowing for high-temperature processing in lead-free environments up to 260 Centigrade (in compliance with the JEDEC J-STD-020C standard). The family offers RoHS compliant straight and right-angle plated pins, and through-hole tails for boards up to 31.75mm thickness. A vertical surface-mount version is also available.
