These connectors are suitable for various applications, including medical devices, telecommunications, and military use, due to their electromagnetic compatibility and robust design.
Connector Selection Process
The document outlines a three-step process for selecting the appropriate connector:
  • Step 1: Choose the connector series based on environmental parameters such as indoor or outdoor use, temperature range, and ingress protection.
  • Step 2: Select the connector size using the cable wire's section or AWG to determine the optimal contact diameter.
  • Step 3: Complete the part number using the series and insulator configuration.
Series Descriptions
  • B Series: Indoor, keyed connectors with various models including metal and plastic housing, elbow sockets, and watertight options.
  • K Series: Outdoor, keyed connectors with similar configurations to the B Series, designed for harsher environments.
  • S Series: Indoor connectors with a stepped insert, offering metal and plastic housing models.
  • E Series: Outdoor connectors with a stepped insert, providing watertight and vacuumtight models.
  • L Series: Outdoor, keyed connectors with stepped inserts, offering vacuumtight models.
  • G, C, D Series: Indoor connectors with unique features such as hermaphroditic insulators and concentric contacts.
Technical Features
LEMO connectors are known for their push-pull self-latching system, which ensures secure connections resistant to vibration and shock. They are UL recognized and conform to the RoHS directive, ensuring safety and environmental compliance.
Additional Information
The document includes details on spare parts, accessories, tooling, panel cut-outs, and technical characteristics, providing a complete guide for selecting and using LEMO connectors.
Ingress Protection (IP) Code Overview
The document outlines the IP code system as per IEC 60529, which classifies the sealing effectiveness of electrical enclosures against foreign bodies and moisture. The IP code consists of two digits: the first digit indicates protection against solid objects, while the second digit indicates protection against moisture.
Device Protection Recommendations
  • For outdoor devices requiring IP66 or above, use watertight sockets from specified series (B, S, E, K, or L).
  • Devices under pressure differences should be tested for helium leakage as per MIL 1344A standards.
Connector Selection and Specifications
  • Connector size selection depends on contact diameter and the number of contacts required.
  • Ensure the selected contact diameter fits the cable wire diameter (AWG number or max section).
Contact and Cable Specifications
Tables provide detailed specifications for contact diameters, cable diameters, and fitting requirements for various series and models. Ensure compatibility with your cable diameter and application needs.
B Series Connectors Features
  • Push-Pull self-latching system for security.
  • Available in multipole types with 2 to 64 contacts.
  • Options for solder, crimp, or print contacts.
  • High packing density and multiple key options for alignment and EMC shielding.
Part Numbering System
Examples of part numbers are provided, detailing the configuration, series, and specifications of connectors, including fixed sockets, free sockets, and straight plugs.
Specifications
The document provides detailed specifications for various series of connectors, including dimensions, materials, and technical characteristics for different series and types of connectors.
Procedures
PCB drilling patterns and panel cut-outs are referenced for proper installation, with specific pages indicated for detailed diagrams. Assembly instructions include notes on ordering additional components like bend reliefs and cable assemblies.
Standards and Recommendations
Surface treatment standards follow SAE AMS QQ N 290 for nickel and ISO 27874 for gold. Electrical characteristics such as test voltage and rated current are specified for each model, with cautionary notes on calculation methods.
Key Features
Connectors are designed for high electrical insulation and EMC screening efficiency. Mechanical and climatical characteristics include endurance, humidity resistance, and temperature range specifications. Special features like earthing tags, cable collets, and non-latching mechanisms are highlighted for specific models.
Notes
Length "L" varies depending on the number of contacts, with specific references to tables for detailed information. Some models require additional components to be ordered separately, such as bend reliefs.
Mechanical Endurance
The document specifies a mechanical endurance of 5000 cycles for the latching system, measured according to IEC 60512-7 test 13a. This endurance indicates the number of cycles after which the system remains effective.
Force Measurements
Forces were measured on outer shells not fitted with contacts. The document provides detailed force values (Fv, Fd, Fa) for various series, including Standard, Watertight, and Keyed series.
Electromagnetic Compatibility (EMC)
The document emphasizes the importance of EMC in device design, highlighting the need to reduce electromagnetic disturbance emissions and ensure immunity. LEMO connectors with metal shells and earthing crowns are designed for optimal shielding efficiency, measured according to IEC 60169-1-3.
Insulator Materials
LEMO uses various thermoplastics like PA 6.6, PEEK, PTFE, FEP, and PI for insulators, selected based on electrical and thermal properties. The document details characteristics such as dielectric strength, volume resistivity, and radiation resistance.
Contact Materials and Treatment
LEMO contacts are made from materials like bronze beryllium and brass, chosen for their elasticity, conductivity, and mechanical strength. The document outlines surface treatments, including nickel and gold plating, to enhance performance.
Crimp and Solder Contacts
The document describes the advantages of crimping, such as high tensile strength and no risk of heating the insulator. It also covers solder contacts, detailing the conductor bucket design for optimal solder flow.
Voltage and Current Ratings
Test and operating voltages are specified according to IEC standards, with considerations for altitude and safety requirements. Rated current values are provided, with adjustments for temperature and conductor dimensions.
Cable Fixing Systems
LEMO connectors use cable collet systems for secure cable retention, with options for hexagonal crimping in the 00 multipole series.
Specifications
The document provides detailed specifications for various series of connectors, including the K, S, and E series. It outlines the components of plugs and sockets, such as collet nuts, collets, flexible gaskets, earthing cones, split insert carriers, insulators with contacts, and housing subassemblies. The document also specifies the maximum tightening torque for metal and plastic collet nuts across different series, including standard, watertight, keyed, and watertight keyed series.
Procedures
Assembly instructions for different series are available on the LEMO website. The document emphasizes the importance of using proper tools and trained personnel for connector assembly and installation to ensure safe and reliable performance.
Standards and Norms
The document references various standards, including the IEC-60228 standard for wire gauges and VDE regulations for maximum current ratings. It also provides conversion formulas for units and highlights the importance of adhering to national and international safety regulations.
Recommendations
Recommendations include using epoxy resin to fix collet nuts in applications subject to strong vibrations and ensuring connectors with exposed contacts are not live. The document advises on the proper handling and inspection of connectors to prevent hazards such as shock and fire.
Product Safety Notice
The document warns against improper handling and use of connectors, which can lead to hazardous situations. It stresses the importance of not disconnecting mated components while live and ensuring that connectors with exposed contacts are not on the current supply side of a circuit.
