Bayonet Connectors

Bayonet is a standardized locking type which is versatile in terms of being used in different product series and industries. The product portfolio of binder includes bayonet connectors in the subminiature category (Bayonet IP40 Series 710, NCC Series 670), miniature category (Bayonet IP40 Series 678, NCC Series 770), power connector category (Bayonet HEC Power, Bayonet IP40 Power), and medical grade (NCC Series 770).
The key feature of this locking technology is the ease of safely locking the connector by turning the locking ring a quarter turn until it latches into the mechanism.

Benefits of bayonet connectors

  • Resistant towards vibrations and shock
    Bayonet locking systems are highly resistant to vibration which prevents connectors from disconnecting and intermittent signal interference.
  • Secured and reliable lock
    Operator recognizes when connector is safely locked due to latching mechanism.
  • Safety
    The design significantly reduces accidental disconnection which can reduce maintenance cost and application failure.
  • Easy to mate and disconnect
    The locking systems is ideal for applications that require fast and easy connectivity without losing time on screwing.
  • High durability
    In order to withstand rough environments in industrial applications, bayonet connectors are designed to be used in harsh conditions where other connectors could fail.

Most innovative bayonet design from binder: NCC technology at a glance

Our most innovative bayonet connector is the NCC (Not Connected Closed) connector. The NCC series 770 is a reliable circular connector in cable and flange versions with bayonet locking corresponded to protection class IP67 when mated. The panel mount version offers IP67 protection even when unmated. 770 series connectors have 8 gold-plated contacts with a rated current of 2 A each. Cable glands are suitable for cables with a diameter of 2.5 to 4 mm, 4 to 6 mm and 6 to 8 mm. Users can expect more than 5000 mating cycles.

The smaller version of the 770 series is the NCC series 670 which can withstand demanding protection requirements. Thanks to a special design feature, the extremely flexible, space-saving subminiature connectors can achieve IP54 protection when unmated and IP67 when mated. This property is beneficial, for example, in test and measurement as well as medical applications that are subject to limited installation space. Other applications include temperature-analyzing instruments, lighting, signage and further equipment in wash-down environments.

All 670-series products are housed in a 16-mm-diameter plastic enclosure. The 5-pin NCC connectors, equipped with gold-plated contacts, are specified for a rated current of 2 A at a rated voltage of 50 V. Their bayonet lock ensures a stable connection. Resistant to vibrations and shock, they operate reliably at -25 °C to +85 °C. The cable outlet measures 3 mm to 5 mm in diameter, and the wire gauge is 24 AWG (0.25 mm2).
