Heavy Duty Circular Connectors


  • Perfect transmission of data and reliable signal integrity using Hypertac Hyperboloid and Tortac contact
  • Special plating to resist under harsh environment conditions along railway tracks
  • Bayonet locking system for easy maintenance and download/upload of new information into the balise
  • Metal shell with conductive plating for shielding available purpose
  • Vibration tests compliant to MIL-STD-1344 method 2004 cond. III- IP67 protection, salt water mist tested
  • Compliant to VG95234, MIL-C-26482.

Heavy duty circular connectors, specifically designed for the compact size and the advanced technical features of the rail Eurobalise system.

The BOA connector ensures reliable signal integrity and perfect transmission of data between the rail track and the train borne equipment, which is key for the performance of the Eurobalise system. The vibration tests are compliant to IS-402 and the connector complies to VG95234, MIL-C-5015, and MIL-C-26482 normative.

Colored plug versions (red, black, green, orange, yellow or depending on the function) and anti-tempering screw system are available.

The connector is IP67 according to IEC 529 when mated with the counterpart.
