K - Outdoor keyed

The K series embodies our heritage of Swiss engineering excellence. Its ruggedised housing and high-quality materials are designed for exceptional longevity. Every component, from the outer shell to the internal contact pins, is manufactured to withstand severe shock, vibration, and extreme temperatures . This ensures stable conductivity and mechanical integrity in the most challenging environments.

The signature LEMO Push-Pull self-latching system provides an immediate and secure locking mechanism. Mating is effortless, yet the connection firmly resists accidental disconnection from cable pull or vibration. Key benefits include:

• Absolute Security: The locking mechanism guarantees connection retention until the user deliberately disengages the connector.
• Ease of Use: A simple axial pull on the outer shell releases the latch, ideal for high-density applications or frequent mating cycles.
• Interface Integrity: The system ensures precise alignment of every contact and pin, protecting against damage and ensuring a reliable electrical interface.

Modern systems demand complex wiring. The K series offers extensive flexibility with numerous multipole and mixed contact configurations. You can integrate multiple contact types—including low/high-voltage electrical, fibre optic , and coax—within a single connector housing. This versatility in termination options simplifies the connectorization process for a more compact and efficient cable assembly.

Engineered to be watertight, mated K series connectors achieve an IP68 protection rating as per the IEC 60529 standard. This signifies complete protection against dust ingress and resistance to continuous immersion in water. This level of sealing is critical for outdoor equipment, underwater devices, and any application exposed to liquids or fine particulates. The robust strain relief and connector body design maintain this protection throughout the product's life cycle.

To meet specific requirements for space, weight, and function, the K series is available in 6 different sizes and multiple shell styles. Whether you need a fixed socket for panel mounting, a free plug for a cable assembly, or a specific adapter, our extensive range ensures you can find an optimised housing and interface for your equipment without compromise.

Global products require adherence to strict international standards. LEMO K series connectors comply with RoHS and other major regulations, including UL (Underwriters Laboratories) recognition where applicable. This certified quality simplifies your product development cycle and ensures your final assembly meets the safety and performance standards required in key markets worldwide.

In the medical and defence sectors , the K series' robust construction and secure locking are ideal for portable medical devices and field-deployed military equipment. Its high-performance shielding guarantees signal integrity by protecting sensitive data from electromagnetic interference (EMI).

For field-based and test and measurement and outdoor broadcast, the K series provides a secure, weatherproof connection for cameras and sensitive apparatus. Its high-performance contacts ensure excellent conductivity for accurate measurements and high-bandwidth transmissions. These robust connectors have become the SMPTE standard and are therefore a familiar sight on professional stadium cameras and other live-event broadcast equipment.

In automation and robotics, systems face constant vibration and fluid exposure. The K series excels by providing a dependable electrical link for sensors and control units. The secure push-pull system prevents disconnection on moving equipment, while the sealed connector body protects internal wiring from industrial contaminants.
