Introduction
LEMO Group, founded in Switzerland in 1946, is a leading global provider of circular Push-Pull connectors. The company offers over 50,000 modular connectors, ranging from 3 mm to 50 mm in diameter, suitable for applications in medical, telecommunications, and military sectors. LEMO connectors are renowned for their self-latching system, ensuring secure connections resistant to vibration and shock.
Specifications
The catalogue describes LEMO connectors with coaxial, triaxial, and mixed contacts, organized into 40 series across 7 product families, including the B, K, S, E, and 00 Series. These connectors are designed for electromagnetic compatibility (EMC) and are available in watertight and vacuum-tight models.
Material and Treatment
Connectors are constructed from materials such as brass, stainless steel, and aluminum alloy, with surface treatments like chrome, nickel, and gold plating. Some models feature anodized finishes or special brass components.
Compliance and Standards
LEMO connectors are UL recognized and comply with RoHS directives, ensuring they are free from hazardous substances. CE marking applies to complete products, not individual components like connectors.
B Series
The B Series features the Push-Pull self-latching system, multiple contact configurations, and high packing density. They provide full EMC shielding and are available in both plastic and metal housing models.
K Series
Designed for outdoor use, the K Series connectors are watertight (IP68) and feature rugged housing for extreme conditions. They share insulators with the B Series and offer similar features like multiple key options and high packing density.
Part Numbering SystemThe catalogue includes a detailed part numbering system for identifying
connector configurations, including series, model, alignment key, housing material, insulator type, and contact type.
Conclusion
LEMO's extensive range of connectors is designed to meet diverse application needs, offering robust, secure, and compliant solutions for various industries.
Overview
This document provides technical specifications and configurations for LEMO connectors, focusing on the PCA 1E 250 C T L C 50 Z free socket. It includes detailed information on part numbers, impedance, voltage ratings, and contact configurations.
Part Number Explanation
The part number PCA.1E.250.CTLC50Z refers to a free socket with a cable collet, part of the 1E series, designed for coaxial cables with 50 Ω impedance. The outer shell is made of chrome-plated brass, and it includes a PTFE insulator. The collet is suitable for cables up to 5.0 mm in diameter and includes a collet nut for fitting a bend relief.
Specifications
