G57 – Modular Circular Connectors

4, 16, 24, 32, 48 pole connector with PE or 4+5 pole connector without PE

G57 series

Our G series connectors are of rugged design providing high-performance reliability and maximun safety in harsh environments. Their modular design lets you build the right connector for every application quickly and easily.

G18, G28, G42, G57 series: G series connectors come in 4 shell sizes and a variety of contact arrangements (2 to 48 contacts). The shells made of aluminium die-cast alloy and featuring bayonet or threaded coupling are highly resistant to shock, vibration and the harsh environmental conditions. The connector is sealed to IP54 and IP67. Our G and GM Series circular connectors are dustproof, pressure proof and water protected. They are also resistant to the effects of most acids and alkalis as well as the extremes of temperature.

Features

  • Shell size reflects the size of the contact insert which has a diameter of 57 mm
  • Contact arrangement: 4, 16, 24, 32, 48 pole connector with PE or 4+5 pole connector without PE
  • Modular design
  • Rugged shell made of aluminium die-cast
  • Electrical and mechanical characteristics to IEC 61984

Applikationen

G Series connectors are specifically designed for applications where reliability under difficult conditions is paramount. The hammer-toned enamelled aluminium die-cast shell makes the connector resistant to a wide range of stresses as they occur in public transport, mining and metallurgy, the marine, construction site, and power plant equipment industries, as well as the environmental and food and beverage sectors.
