Single mode and multimode optical pin and socket termini

▲ TE Connectivity’s EB16 optical pin and socket termini

16 cavities and are compliant with MIL-DTL-38999 Series I and Series III connectors, as well as the MIL-STD-1760 connector. The termini include features that compensate for inherent connector mating misalignments. For a D38999 size 25-37 connector fully loaded with termini, the springless termini can reduce the total axial connector mating force by approximately 150 lbf. The return loss (RL) of the multimode products is now comparable to that of the single mode design. In addition, crimp eyelets and the need for a crimp tool have been eliminated, reducing overall termination time and labour. “For customers who need the performance of a non-contacting optical interface, TE now o ers them the new single mode and multimode EB16 options,” said Gregory Ristau, product line manager for TE’s aerospace, defence and marine division. EB16 termini are designed for a variety of military, commercial aerospace, harsh environment industrial and space applications, including radar and sensor systems; rugged communications networks; xed wing and rotary aircraft; unmanned aerial vehicles; commercial avionics and sensing; military avionics, sensing and ordnance; and military ground vehicles.

TE Connectivity is to release its EB16 expanded beam optical pin and socket termini in new single mode and multimode variations. Both are based on an updated design that includes springless mating and crimpless cable retention. EB16 termini are built on TE’s Pro Beam expanded beam connector technology, which expands and collimates the optical signal into a beam size beyond its original size. This helps to provide easier optical alignment, low sensitivity to contamination and consistent performance over thermal changes. Separating the optical components by an air gap and removing physical contact helps improve performance and reduce damage in rugged conditions such as high vibration and shock. The mated termini engagement length is more than two times deeper than the standard MIL-PRF-29504/4 and /5, which helps improve stability and performance during vibration. As with previous versions, the new EB16 optical single mode and multimode pin and socket termini are drop-in replacements for the MIL-PRF-29504/4 and /5 physical contact termini used in many ruggedised circular connector systems.

Copper-bottomed cleat contract Cable cleat manufacturer Ellis has secured a contract to supply products for a major project in South America. The company will supply its Vulcan+ cable cleats for installation in an $800mn desalination plant, under construction as part of the $2.5bn expansion of BHP’s Spence copper mine in Chile’s Atacama Desert. Kelly Brown, export sales manager at Ellis, said, “Latin America is noted for being one of the hardest export markets to break into. …We took the decision early on to appoint a locally-based business development manager, Gabriela Castro-Fontoura, who has built up a strong network of distributors from her base in Uruguay, and is now enjoying a string of signi cant speci cations.” Ellis Patents Ltd www.ellispatents.co.uk Manufactured in 316L stainless steel, the cleats are designed to provide corrosion protection in harsh environments.
