GR connectors have Quadrax contact for harsh environments

GT series connectors from Amphenol now feature a high speed Quadrax contact which provides high speed transmission in rail and mass transit, heavy equipment and industrial applications.

Quadrax contacts offer more reliable rail mass transit (RMT) application requirements on inter-vehicle connections and database applications than multi-pole connectors without individual shielding, Amphenol explains.

The GT Quadrax connectors combine a reverse bayonet connector and Quadrax contacts that offer one outer contact with four inner contacts spaced to form two 100 to 150 Ohm controlled impedance differential pairs. The GT Quadrax is an alternative to the more expensive DTL-38999 Series III and ARINC-type connectors for harsh environment applications, including Ethernet 100 Bas-T-100 Ohm, Gigabit Ethernet 1000 Base-T-100 Ohm, Fiber Channel-150 Ohm and IEEE1394B FireWire-110 Ohm.

They are also suitable for rolling stock manufacturers, factory automation solution providers and control device manufacturers.

 The contacts feature high EMI shielding performance, reverse bayonet locking for ease of use, high shock and vibration resistance for up to 500 mating cycles and quick positive coupling.

Quadrax contacts have a bandwidth up to 1.25GHz, a data rate exceeding 2.5Gbits per second, a maximum voltage rating of 500Vrms at sea level and 1000V AC rms between all inner contacts at sea level, as well as 500V AC rms between inner and outer contacts at sea level.

The contacts are available in size 8 crimp termination style or with PC tails and available as gold plated contacts, supplied with gold over nickel on mating parts. The outer contact has a rugged wall section for durability.

In accordance with EN60068-1, the Quadrax contacts are rated IP67-IP69K when in the mated condition. Plating from Amphenol Industrial ensures they are RoHS- and REACH-compliant.
