The first slip ring which we developed for use in a winch application was what is known today as our TX4702. Ordered in August 1982 by our customer Expro North Sea, the unit comprised of 8 rings and was given a Baseefa Certificate of Conformity No Ex 821417 to comply with BS5501: Part 1: 1977 EN50 014 and BS 5501: Part 5: 1977 EN50 018, in January 1983.
Initially called product 475, the product became the TX4700 Series in February 1988, and maintains that today. The product has a cast aluminum housing for use in rugged environments and is certified for both ATEX and IECEx applications.
Since this initial development, thousands of the units have been sold worldwide and continue to do so. For further information about the TX4700 Series, please click here.
