W SERIES

Product catalog summary
Overview: This document details LEMO's W Series high-pressure connectors, designed for high liquid pressure environments. LEMO offers a modular design with over 75,000 configurations, suitable for industries such as medical, telecommunications, and military.
Specifications: The W Series connectors range from 2 to 64 contacts, with options for fiber optic or hybrid types. They include solder or crimp contacts, a keying system for alignment, multiple key options to prevent cross-mating, and 360° EMC shielding. The connectors are built with rugged housing for extreme conditions.
Design and Features: These connectors use a screw coupling system with an O-ring for watertightness, replacing the traditional Push-Pull latching system. An adhesive heatshrink boot is required post-assembly for cable-side watertightness.
Compliance and Safety: LEMO connectors are UL recognized, RoHS compliant, and CE marked, indicating adherence to European safety directives. Users should follow safety instructions to avoid hazards.
Technical Characteristics: The connectors withstand over 1000 mating cycles, operate from -20°C to +200°C, and provide IP68 protection when mated. They resist hydrostatic pressure up to 30 bars and offer high shielding efficiency.
Models and Variants: Models such as FVG, EVG, PVG, HRG, and HVG are listed, each with specific dimensions and configurations. Vacuumtight models are available for high protection needs, identified by an additional 'V' in the part number.
Applications: Suitable for nuclear physics, petroleum industry, portable radios, military, laboratory equipment, and aviation.
Assembly and Ordering: Detailed part numbers and configurations are provided, including options for bend relief and vacuumtight versions. Users should consult the catalog for specific assembly instructions and additional options.
Hazardous Voltages: Voltages above 30 VAC and 42 VDC are hazardous. Measures should prevent these voltages from reaching exposed metal parts of connectors.
Test and Operating Voltages: Maximum operating voltage is determined by standards. Air and creepage distances affect operating voltage, influenced by PCB design or wiring harnesses. Test voltage is 75% of the mean breakdown voltage, applied at 500 V/s for 1 minute.
CE Marking: CE marking indicates compliance with European safety directives and applies to complete products, not individual components.
Product Improvements: LEMO reserves the right to modify products or specifications without notice.
Proposition 65 Warning: LEMO products are exempt from Proposition 65 warnings as they are for commercial and industrial use.
Contact Information: Contact details for LEMO subsidiaries and distributors in various countries are provided.

W SERIES-3

W Series W Series connectors have been developed for utilisation where protection must be guaranteed under high pressures of liquids. The basic elements, insulators, contacts and clamping system are from the B series. The push-pull latching system has been replaced by a screw coupling system with watertightness maintained by compression of an O-ring in FPM (Viton®) according to the triangular shaped cavity principle. There are multiple application possibilities ranging from nuclear physics to the petroleum industry. After cable assembly, the rear part must be covered by an adhesive heatshrink...

Vacuumtight models HRG and HVG socket models allow the device on which they are fitted to reach a protection index of IP68 as per IEC 60529. They are fully compatible with plugs of the same series and are widely used for portable radios, military, laboratory equipment, aviation, etc. These models are made in a vacuumtight version. They are identified by an additional letter «V» at the end of the part number (certificate on request). Epoxy resin is used to seal these models and we are offering 2 different resins: a) Epoxy Araldite®, for general purpose use, identify with letter «P» b) Epoxy Stycast®,...
