K Series

LEMO K Series – Sealed Connectors for Harsh & Outdoor Environments

The LEMO K Series delivers high-reliability circular interconnect solutions engineered for outdoor, industrial and harsh-environment applications where protection against the elements is critical.

Designed for long-term performance in challenging conditions, the K Series ensures dependable connectivity across field-deployed equipment, mobile systems and exposed installations, where dust, moisture and environmental stress are constant factors.

Engineered for Extreme Outdoor Conditions

The K Series is purpose-built to withstand harsh environments, providing a robust barrier against external elements:

  • Advanced multi-layer sealing system for protection against dust, dirt and moisture
  • IP68 sealing when mated (submersible conditions) and IP66 when unmated
  • Reliable performance in exposed outdoor and field environments
  • Durable construction for long-term environmental resistance

This makes it ideal for applications where environmental protection and system uptime are essential.

Reliable Performance in Harsh & Field Environments

Designed to maintain connectivity in demanding conditions, the K Series supports consistent operation
across industrial and defence platforms:

  • Resistance to shock, vibration and mechanical stress
  • Stable performance in outdoor and mobile systems
  • Reduced maintenance requirements in exposed installations
  • Proven use in field-deployed and ruggedised applications

Widely used across both industrial systems and defence platforms, the K Series ensures reliability
where failure is not an option.

 

Optimised for Outdoor, Industrial & Defence Applications

The K Series is ideally suited to:

  • Outdoor and exposed equipment installations
  • Field-deployed industrial systems
  • Mobile and transportable platforms
  • Defence and tactical systems operating in harsh environments
