What are the key features of B5743-206-M-L-3?
- 6-contact (3+3) DIL dual-in-line male horizontal plug with 3 mm throughboard tail for secure PCB anchoring
- Integrated latch mechanism provides positive connector retention, preventing accidental disconnection in vibration-prone environments
- Gold-plated termination contacts ensure low contact resistance and extended mating cycle reliability
- Datamate L-Tek Series design compatible with standard Harwin Datamate mating sockets for modular system interconnects
What is B5743-206-M-L-3 used for?
The B5743-206-M-L-3 is used in compact modular electronics where secure, reliable board-to-cable or board-to-board connections are required in 6-position dual-in-line configurations. Its latch mechanism makes it suitable for field-replaceable modules in industrial test equipment, aerospace electronics, and military-grade embedded systems where accidental unmating must be prevented during operation. The 3 mm throughboard horizontal design is ideal for right-angle PCB edge connections in tight enclosures and stackable module systems.

Frequently Asked Questions
How does the latch mechanism on the B5743-206-M-L-3 improve connector reliability in vibration environments?
The integrated latch on the B5743-206-M-L-3 secures the mating connector with a positive click-lock that resists accidental disconnection under vibration and shock loads. This is critical in aerospace, military, and industrial applications where vibration levels may exceed 10 g and standard friction-fit connectors could work loose, interrupting signals across the 6 gold-plated contacts.
What contact count and layout does the B5743-206-M-L-3 use, and how does this determine the mating socket selection?
The B5743-206-M-L-3 has 6 contacts arranged in a 3+3 dual-in-line (DIL) configuration. Engineers must select a compatible Harwin Datamate L-Tek female socket that matches the 3+3 DIL layout and 3 mm throughboard pitch. This standardized Datamate Series footprint ensures interoperability with other Harwin Datamate connectors in the same product family.
What does the 3 mm throughboard specification mean for PCB design with the B5743-206-M-L-3?
The 3 mm throughboard dimension refers to the length of the connector tail that passes through the PCB. Designers must ensure the PCB has the correct hole diameter and spacing for the 6 contacts, and that 3 mm of clearance exists on the solder side for the tails. The horizontal orientation means the mating direction is parallel to the PCB surface, requiring adequate clearance in front of the connector for cable or board connection.
When should a designer choose the latched B5743-206-M-L-3 over a standard unlatched 6-pin connector?
The latched B5743-206-M-L-3 is the better choice when the application involves mechanical shock above 5 g, continuous vibration, or frequent cable handling that could inadvertently disconnect an unlatched plug. It is particularly valuable in portable instruments, robotics end-effectors, and avionics boxes where 6 signal lines must remain continuously connected throughout the equipment's operational life without relying on friction retention alone.
