Weidmuller Attains UL Certification for Crimped Wire Contacts

weidmuller

RICHMOND, VA (October 27, 2014) - The classic definition of a wire-end ferrule is a tinned copper sleeve, which is placed onto the end of the wire where it is crimped. In other words, wire-end ferrules are used to insert the conductor into the connection or terminal compartment, protecting the fine strands of a multi-stranded wire and providing a gas-tight connection that prevents air or gasses (that lead to corrosion) to permeate. Laboratory tests have proven that the use of ferrules can extend contact lifetime by preventing an increase in resistance and temperature, which can lead to short-circuits and/or failures. Evidence in support of the prolonged contact lifetime, in addition to a more complete list of benefits, can be found in Weidmuller’s white paper entitled, “Ferrules: Your Best Insurance against Costly Connection Failure”.

Complying with UL recommendations for ferrule crimping, the ferrules were tested and certified only after being crimped to a wire using Weidmuller hand tools and automatic wire processing machines. Therefore, the UL certification is valid only if the wire-end ferrules are processed with Weidmuller tools. The hand held tools utilized during the testing process were the PZ 4, PZ 6/5, PZ 3, PZ 6 Roto, and the PZ 16 for wire-end ferrules with plastic collars. Weidmuller’s automated wire-processing machines included the “Crimpfix” series of strippers and crimpers, the PowerStripper machines, and the CA 100 stripper and crimper.

Weidmuller offers a comprehensive assortment of wire-end ferrules (to DIN 46228, Paragraphs 1 and 4), with and without plastic collars for nominal cross-sections ranging from 0.14mm² to 50.0mm² (AWG26-0). In addition, Weidmuller offers a line of precision wire preparation tools, such as: cable and wire cutting tools, insulation strippers, ferrule and lug crimpers, pliers, screwdrivers, and more.
