Ideal for use with higher vibrations and impacts

A bayonet lock is a fast producible and detachable mechanical connection of two cylindrical parts in their longitudinal axis. The parts are connected by nesting and counter rotating and so also separated again. Thus, the coupling of a bayonet Steckvertbinder pair is very easy from equip. In addition to easy handling, this type of coupling impresses with its high vibration resistance.

Bayonet couplings are used wherever robust and safe electrical connections with metal housings are required. Optimum solutions are offered by the large number of contact images and housing shapes.

The most important key data of the MS connectors are:

  • HOUSING: Aluminum alloy for high mechanical strength with low weight.
  • SURFACE PLATING: Standard is olive green chromated over cadmium for corrosion resistance and use in extreme operating conditions. Also available are RoHS compliant surfaces nickel, zinc cobalt (black), zinc cobalt (green).
  • CONTACT SUPPORT: The standard material for insulators is neoprene (polychloroprene), which offers high insulation resistance, high dielectric strength and shock and vibration resistance. Other materials such as Viton or a flame-retardant halogen-free compound, with low smoke emission are also available.
  • CONTACTS: Copper silver plated or gold plated, available for currents from 10 amps to 150 amps. These offer excellent conductivity under harsh operating conditions with minimal contact resistance. Both solder and crimp terminals are available.

The large number of over 110 insert assemblies in 13 package sizes for power, signal or combinations of power and signal configurations cover a wide range of applications. On request, connectors with leading contacts, earth contact connection to the housing, EMI RFI shielding, PG adapters and cable glands (PG and metric) are available.

To the right you will find a selection of technical data (further information can be found in the catalog).
