Modular Connectors, G and GM series

Product catalog summary
Overview: The document is a technical catalogue for the G and GM series modular circular connectors, designed for high-performance reliability in harsh environments. These connectors are used in various industries including railway engineering and industrial applications.
Features: The G and GM series connectors are modular, allowing for customizable configurations. They are available in different shell sizes and contact arrangements, with the G series featuring metal shells and the GM series featuring thermoplastic shells. Both series offer high resistance to environmental stresses and are sealed to IP54 and IP67 standards respectively.
Applications: G series connectors are suitable for demanding conditions in industries such as public transport, mining, and marine. GM series connectors are a cost-effective alternative for applications that can utilize plastic connectors.
Specifications: The document details specifications for various series including G18, G28, G42, G57, and GM42. Key specifications include contact arrangements, rated voltage, maximum rated current, contact resistance, insulation resistance, operating temperature range, and degree of protection.
Materials: The connectors are made from high-quality materials such as aluminium die-cast alloy for the G series and Polyamide-6 for the GM series. Contacts are made from brass and copper wrought alloy, with options for silver or gold plating.
Standards: The connectors comply with IEC 60512, IEC 61984, and IEC 60529 standards, with a material flammability rating of UL 94-V0.
Assembly and Tools: The document provides guidance on assembling the connectors and lists the necessary tools for assembly and mounting.
Crimp Contacts Overview: This section provides detailed specifications and guidelines for crimp contacts used in electrical connectors, including contact types, dimensions, wire gauges, and current ratings.
Crimp Contacts Specifications: Various contact types are detailed, including Type H (3 mm diameter) and Type G (1.6 mm diameter). Intermateability is noted, with the 14 pole insert for crimp contacts being compatible with the 10 pole insert for solder contacts. Protective conductor terminal details are provided.
Contact Inserts: Pin and socket inserts are available in configurations such as 6+2+PE, 10+PE, 12+PE, 14+PE, 20+PE, and 64+PE. Protection caps for series GM42 include GM42 VK and GM42 VD.
Contact Dimensions and Identification: Wire gauge and current ratings are specified, with AWG 20 supporting 7.5 A, AWG 18-16 supporting 10 A, AWG 14 supporting 16 A, and AWG 12 supporting 27.5 A. Ordering codes for pin and socket contacts include identification grooves for easy recognition.
Graphs and Charts: Graphs illustrate permissible operating currents at various ambient temperatures for different contact configurations.
Recommendations: It is recommended to ensure PE contacts are at least the same AWG size as the main contacts and to use filler plugs for unimplemented contact cavities to maintain integrity.
